Folding sheet metal boxes with special RollBend tooling

Monday, July 25th, 2016

Bending aluminium boxes

Here at V and F Sheet Metal we are folding up a wide range of sheet metal components on a daily basis. They can be small electronics screening cans in 0.3mm tin plated mild steel, 0.4mm special pre-anodised reflector aluminium alloys, 0.9mm zintec coated mild steel channels, 1.5mm pre-galvanised mild steel lighting gear trays, 2mm brushed stainless steel housings, 3mm copper bus bars, 4mm mild steel support angles, 19” rack aluminium components and so much more. The sheet metal work that we fold up may have just a single simple angle bend right through to multiple bent complex parts with easy bends, safe edges and multi bent curved sections. When folding sheet metal boxes we can employ a number of different machines and tooling techniques to make the right part for you.

Today we are going to look at a component that has electrical cut-outs cut in a 3mm thick aluminium part which will cause a problem is they are folded up with normal air bending V tooling. The problem with using standard V bend tooling with cut-outs that are too near the bend line is the unsupported material that will be in the die bend zone will not fully bend up. This problem is increased with the increase in the sheet metal component thickness. Once way around this would be to bend up the components first and then machine in the cut-outs after which is acceptable but slow and would lead to an expensive part. The tooling technique we use to solve this problem is to use a range of RollBend tooling from Trumpf. This tooling can be used in both our Trumpf 7036 and Safan e-Brake CNC press brakes enabling us to cover a wide range of tricky bending work.

The RollBend tooling rotates around 2 fixed points enabling the bottom tool to fully support the material as its being folded with no air gap. The machine can be set up with the standard top V tooling and can be run at the same speed as normal so importantly the part price is not affected by using this type of tooling. The set time is just as quick as using the normal bottom bend tooling and just drops straight into place in the bed of the machine.

Folded aluminium boxes

Here is the 3mm thick aluminium gear box folded up and ready to have a number of bushes and studs inserted before powder coating. You can see that the 2 circles and the 2 rectangular cut-outs have all the material between the cut-outs and the bend line bent up properly and require no other operations to straighten out the material.

CNC punching sheet metal work in Hampshire, UK

If you are looking for a sheet metal working company to CNC punch out your sheet metal components then V and F Sheet Metal based in Fareham, Hampshire, UK are just what you need. As well as a Trumpf 3030 3KW fibre laser machine we have Trumpf 200 and Trumpf 3000 CNC punch presses. These punch presses are very flexible machines being able to punch out components from 0.3mm to 5mm thick material in a wide range of metal materials. From 0.3mm tin plated steel and 0.4mm thick specialised aluminium lighting reflector materials, standard aluminium, mild steel, stainless steel alloys through to 5 bar tread plate, pre-painted steel and pre-anodised aluminium. All stainless steel and aluminium alloys can be supplied with plastic coatings on their top and bottom faces to prevent damage in production and during your assembly stages.

The machine shown here is our Trumpf 3000 CNC punch press punching out pre-painted mild steel sheet metal. The circular discs are gear trays for industrial light fittings and are very competitively priced compared to manufacturing from mild steel and powder coating white. The final punch on this part would be to sever the component from the parent material and collect it in a tray underneath the machine from a programmable chute in the machine bed.

The Trumpf machines having a single head which can rotate through 360 degrees make them very flexible when it comes to complex sheet metal designs and small batch work. This flexibility can be advantageous when it comes to your designs with the ability to punch slots at any angle, cut-outs in complex shapes with our standard FREE CNC punch tooling.

These CNC punch presses are fully supported in all manufacturing features by our Radan sheet metal CAD/CAM software as well as offering 3D modelling for accurate bank size calculations it allows us to swap jobs from our laser to our CNC punch presses when production work loads necessitate.

Looking for a sheet metal worker with the flexibility and expertise to handle your production projects in a range of sheet metal materials, please give V and F Sheet Metal a call on 01489 577786 or e-mail your drawings to sales@vandf.co.uk and our engineering team will be happy to review them for you.

Folding sheet metal housings

Friday, May 20th, 2016

Safan CNC press brake in action

Our Safan e-Brake CNC press brake is such a versatile sheet metal folding machine. We can fold up sheet metal components from just a few mm across to 3M long sections all with the same bend tooling. Programming is so easy that a new project can be programmed in a matter of minutes and saved away to our system server to be called back whenever the part is needed for repeat orders.

Mild steel housings folded

Simplicity is the key to a quick setup of a sheet metal component. When you are moving from one job to another throughout the day it’s not just about the speed of bending that saves time and money but the machine setup and programming time. The Safan e-Brake scores well on this account with a clear, simple touch screen control system and a full library of CNC tools shared with our 2 Trumpf 7036 CNC press brakes.

Mild steel housing CNC punched blank

The initial product blanks were produced on our Trumpf 3000R CNC punch press from 0.9mm mild steel. Products like this are typical of the sub-contract sheet metal work service we offer our customers, taking a design and programming it to be CNC punched or laser cut and folded up ready for welding, bush and stud insertion and powder coating.

If you need to purchase some sheet metal housings or brackets please give us a call on 01489 577786 or e-mails us your drawings or photos to sales@vandf.co.uk and we will be happy to help you.

Pressing in studs with fly-presses

Saturday, May 14th, 2016

Flush head studs inserted into sheet metal products

Fly presses in action

We use flush head studs to provide a permanent stud (male thread) into a range of sheet metal materials and thicknesses. They might be aluminium, stainless steel but by far the most popular are mild steel and zinc plated studs. They come in a range of lengths from 6mm up to 50mm and from M2.5 to M8, other sizes can be achieved by special order. They act as a permanent screw thread in place of a screw for assembling components and are often used for an earth point in electrical cabinets and electronics chassis and gear trays. The example show here is of a light fitting gear tray and the studs are used a fixing positions for a lighting ballast.

Lighting gear trays with flush head studs

The studs are often pressed in with our Haeger bush and stud inserter machine. It can cope with all studs, bushes, stand-offs and tank bushes. In this case we are showing one of our fly-presses being used to insert M3 x 18mm mild steel zinc plated flush head studs.

If you have a sheet metal component design and you are not quite sure what you need please just give us a call and we will be more than happy to help you with finding the right insert to suit you. Call us on 01489 577786 or send us your designs to sales@vandf.co.uk

Folding long sheet metal profiles

V and F Sheet Metal have been manufacturing sheet metal work and welded fabrications for over 30 years now. We supply a wide range of sheet metal products from our base here in Fareham, Hampshire to companies in Hampshire and right across the UK to the lighting, heating, electronics and professional audio industries as well as a wide range of specialist companies across the UK. We often deliver products to Winchester, Eastleigh, Southampton, Portsmouth and Basingstoke as well as using overnight services to Scotland, Wales and the rest of the England.

When you are making long channel sections like these you need a bending machine that can provide the bending power and accuracy on bend size and angle right up to 3M long. Our Safan e-Brake 100 ton CNC press brake is just such a machine. Installed new in 2015 this machine is perfectly suited to the range of sheet work we tend to bend and provides a bending force that matches the longest work we can laser cut.

Sheet metal bending

You can see here the guillotined blanks on the right hand of the bending machine and the finished folded U channels on the left hand side of the machine. You need a fair bit of space when it comes to producing parts like these and our 13,000 sq. ft. factory provides the flexibility to take on this type of work as well as higher volumes of smaller parts. You only have to look through some of our past blog posts and the gallery pages on the website to see the wide range of sheet metal work that we get involved with for our customers. From these 3M long sections to CNC punched and folded aluminium lighting gear trays, stainless steel support brackets, mild steel electrical cabinets, copper bus bars, brass display units, aluminium LED display PCB plates etc.

Bent galvanised steel sections

The final 3M long galvanised mild steel sections stacked on a pallet ready to be wrapped up and delivered to the customer. This batch was for 2 different channel cross sections and approximately 350 of each type.

Simple sheet metal work

A simple sheet metal plate made from mild steel sheet. The parts have been CNC punched out on our Trumpf 3000 CNC punch press and they will be barrel de-burred to remove any sharpness from the CNC punching process before shipping to the customer. A simple sheet metal part, easily made in seconds on a CNC punch press and there’s not much else to say about this part except its typical of many simple parts we manufacture every day of the week here at V and F Sheet Metal.

Have a simple sheet metal component that you need for your project, please give us a call on 01489 577786 or e-mail your drawings to sales@vandf.co.uk and we will be happy to help you.

Sheet metal manufacturing

Monday, May 9th, 2016

A range of sheet metal parts demonstrating CNC punching, CNC laser cutting and CNC bending in a sub-contract manufacturing environment. Virtually all the sheet metal projects that we manufacture for our customers use one or more of these production processes to produce the parts to our customer’s design. This is where most investment goes and the technology is supported by sophisticated software and control processes. Some of these parts can be laser cut or CNC punched out from standard sheets of metal in seconds and with quick setting CNC press brakes can be bent in minutes. These techniques lead to competitive prices for small batches of parts when our customers cannot commit to higher volumes.

To see the advantages of these production techniques in a modern manufacturing factory please contact us with your project. You can speak to our engineering team on 01489 577786 or send us your drawings in DXF, DWG, SAT, STEP or PDF format and we will be happy to help advise you on your designs and produce prices for you.

Laser cutting sheet metal light fittings

Thursday, May 5th, 2016

Laser cutting sheet metal light fitting gear trays

I always like it when a laser cutting or CNC punching nest completely fills a sheet of metal. This laser cutting nest of 0.7mm zintec lighting gear trays was just such a job. Being able to get the most from a sheet of metal helps to keep the costs down for our customers and speeds up production with less handling time. The middle image above shows this really well and the other two detail some of the features that were so easily laser cut. After several small batches of samples and development work this was the first production batch of 100 parts. If the volumes increase to many hundreds per batch then I may well look to move this job to one of our Trumpf CNC punch presses to increase the speed that the holes are processed but at the moment the Trumpf fibre laser is perfect for this job. Being able to move jobs between different production methods is a useful way of saving our customers money and time when a particular machine is busy.

If you have a sheet metal project that needs to be laser cut or CNC punched please give us a call on 01489 577786 or send us an e-mail with your drawings to sales@vandf.co.uk

Welding mild steel plates and bars

Wednesday, May 4th, 2016

Welded fabrications

Here’s an unusual project for us here at V and F Sheet Metal, a welded plate and bar fabricated assembly. The bars have been machined from mild steel and free issued to us. We laser cut the circular plates and then welded them in plate as you can see in the image here. Finally we had the welded assembly zinc plated and colour passivated. The final welded fabrication was used to support light fittings in the ground.

Although we predominately produce our work from sheet metal in ferrous and non-ferrous alloys we do also make up fabrication like this when needed for our customers. When you are a sub-contract engineering company you have to be able to turn your hand to any project that comes along from your customers.

Perhaps you are looking to have a welded fabrication project manufactured in the near future, please give us a call and we will be happy to help you.

Sheet metal components in April 2016

Sunday, May 1st, 2016

Sheet metal components

Here we are at the end of April and here’s another couple of sheet metal components that we have made this month. They are typical of the sheet metal components we make on a daily basis for our UK and European customers and they were each made in batches of several hundred. The components have been CNC punched and bent up from zintec coated mild steel sheet metal. If you click on the image you can see 3 holes in the middle of the component that have a plunged form and are used with self tapping screws. We have the tooling for M3, M4 and M5 as standard in our Trumpf CNC punch presses. Once we had finished them they were used to hold control gear for industrial light fittings and were just left self colour zintec as this was good enough for the warm dry environment into which they were going.

Sheet metal brackets

These brackets were laser cut and then CNC folded on one of our CNC press brakes. They were also made from zintec sheet metal and are used by a pump control company to hold a pumping system in place where beer is pumped from the kegs to the bar in public house cellars.

For more information on sheet metal components and how we go about making them take a look at our web page “What is sheet metal and how is it made”

Folded sheet metal work

Wednesday, April 27th, 2016

Folded stainless steel brackets

Stainless steel folded brackets

Here are two recent folded sheet metal work projects I have chosen at random to demonstrate the versatility of sheet metal. These stainless steel brackets have been laser cut with the fibre plastic protective film in place and then folded again on our Trumpf 7036 CNC press brakes. These brackets were made in a batch of 30 parts and are made perhaps twice a year. Both CNC bend programs along with the CNC punching and laser cutting programs are stored on our company server and are available to the machine setters as all the CNC machines are on our company network. This leads to quick retrieval of past programs and storage of updates for any person who needs to access them.

Folded aluminium brackets

Aluminium folded brackets

These 1.2mm thick aluminium brackets have been CNC punched and folded up on one of our Trumpf 7036 CNC press brakes. The batch size was 250 parts and they were a repeat order which we make several times a year. We can manufacture virtually any type of sheet metal brackets in mild steel, galvanised steel, zintec, aluminium, stainless steel, aluminium alloys, copper, brass or pre-painted materials. For more examples of sheet metal brackets please take a look at our gallery.

Please give us a try and we will be happy to quote for your folded sheet metal work needs.

Laser cutting copper sheet metal work

Monday, April 25th, 2016

Laser cutting copper sheet metal

Having a fibre laser cutter has been a great advantage to us when it’s come to cutting out blank shapes from copper sheet. These simple triangle shapes could have been CNC punched but we would have wasted more material, we would have had to edge de-burr all the shaped to remove the CNC punch marks and the process would have been a lot slower. The Trumpf 3030 fibre laser cutter cut the parts straight out without any edge de-burring and used all the sheet here possible to get the best fit of components.

Laser cut copper sheet metal parts

The pattern of copper triangles was arranged by using our Radan CAD/CAM software with it’s schedule module. It enabled us to mix several different shapes and sizes of copper parts together all laser cut from the same thickness sheet to save material and money across the whole project. Whenever we are working with expensive materials like copper sheet we try all possible solutions to get the best material yield when quoting for the work and then actually laser cutting it.

If you have a sheet metal project in copper or brass and you have been told it can’t be laser cut, look again, up to 6mm thick and we can laser cut it for you.

Bending large sheet metal trays

Friday, April 22nd, 2016

Large folded stainless steel trays

Our new Safan e-Brake 3M CNC press brake is more than capable of bending these large stainless steel roofing trays with it’s 100 Ton bend press force. These 1.5mm stainless steel trays were laser cut from 3M x 1.5M sheets with only one coming from each sheet. They were then bent up on the press brake before finally having each corner joint seam welded to produce a water tight roofing tray for living roof systems. As well as folding large stainless trays such as these show here you can find us on most days folding zintec profiles, aluminium boxes, stainless steel brackets, pre-painted gear trays or mild steel enclosures. The Safan e-Brake is such a versatile machine for bending sub-contract sheet metal work that it was definitely the right machine for us.

CNC press brake bend tooling

The tooling system with the Safan is very flexible, it’s show here with swan neck tooling ready to fold the deep stainless trays shown above. It allows us to share tooling with our 2 Trumpf 7036 CNC press brakes across it’s 3M long bed. By using extension adaptors we can fold very deep sections, trays, boxes etc. as well as safe edge, standard V bends and tight sections using swan neck tooling.

If you have a sheet metal project that needs bending, the chances are we will have standard tooling at no cost to yourself that we can use to produce your parts. Why not send us your drawings and we will be happy to take a look and produce some prices for manufacturing.

Small sheet metal brackets

Wednesday, April 20th, 2016

Small sheet metal brackets

Small sheet metal brackets are a typical component for V and F Sheet Metal to manufacture. We regularly make just a few small brackets for a special project or repeating batches of many hundreds. Some of our sheet metal projects can be for many thousands of small bracket either CNC punched, laser cut of with dedicated tooling. These particular small brackets were CNC punched and CNC bent using our Trumpf sheet metal manufacturing equipment.

If you are looking to have small sheet metal brackets manufactured to your own designs then please give us a call on 01489 577786 or send us an e-mail with your drawings and we will be happy to help you with price options, design ideas and production. If you are looking for a KanBan call off that can be organised as well to suit your volume needs.

CNC punched earth bars

Monday, April 11th, 2016

Sheet metal earthing bars

When you want images, numbers, letters or symbols stamped into sheet metal that are permanent there’s no better way than using a CNC punch press. We have 2 CNC punch presses and both can take the same tooling enabling us to be flexible when it comes to production. These earth symbols have been CNC punched using a customer made punch tool and are clear even after zinc plating.

If numbers or letters are needed there are several tooling options which can be used such as alphanumeric holders for part numbers and stock codes. Larger images can be stamped in one hit but the clarity depends on the material and needs careful design and advise from the tool makers.

I would always say it’s worth asking us if you have an idea that needs stamping into a sheet metal product and you are not sure because we are always happy to check the feasibility with the tool makers for you before you need to commit to any tooling costs.

Rolled mild steel sheet metal rings

Thursday, April 7th, 2016

Rolling mild steel rings

A simple rolled mild steel ring for a light fitting manufactured from 0.9mm thick material. This simple component has been CNC punched from sheet metal, rolled into a ring and then stitch welded at the joints to produce a circular band. Once the bands were all welded together they were then welded to a perforated disc to produce a vented top panel for a high bay light fitting. If you look carefully at the picture you can see small tabs on the edges of the rings which have been designed to engage in slots on the perforated rings to speed up welding alignment. You will see this technique again and again in our blog posts as it’s such a powerful way of ensuring accuracy in welding and speeding up production rates without costing a lot of money.

Perhaps you have a sheet metal projects that is welded together from several parts and this technique could save time and money. We are always keen to help you and would be happy to take a look at your design and see if we can save you money. Please call us on 01489 577786 or send your designs to sales@vandf.co.uk

Laser cut stainless steel grids

Tuesday, March 29th, 2016

Laser cut stainless steel grid

We had a project to produce stainless steel drainage trays for a customer of ours who makes living roofs. The type of roofs that have grass and plants growing across them on schools, bus shelters, nature hides etc. The roofing systems have a series of stainless steel trays laid over the roof with the plants growing and a drainage system to take the water away. The trays have welded corners and a simple gutter / down pipe system to take the rain water away. Inside each roof tray there is a filter system consisting of this stainless steel grid which is welded in place around a drainage hole allowing a filter media to be positioned to hold back the growing media.

The stainless steel grid was laser cut from the same parent sheet as the drainage trays and designed to fit perfectly with small tabs that located into slots in the tray to aid positioning when being welded. We even left more material when we had to bend the grids so there was enough stainless to bend cleanly, this is the advantage of using a laser cutting machine even on small volume projects.

Bespoke sheet metal work from V and F Sheet Metal in Fareham Hampshire

Monday, March 21st, 2016

Here we have 3 quite varied examples of sheet metal work manufactured in our modern factory. They show perfectly the flexibility of production equipment we have when producing batch sheet metal work for our customers.

Laser cut brass clamping strips

One of the more unusual materials that we work with from time to time is CZ108 brass sheet. We could have CNC punched these parts but with the complex arrangement of curves, several special shaped punch tools would have been needed which the 250 off batch didn’t really support. Luckily having a Trumpf fibre laser machine cutting brass up to 6mm thick isn’t a problem for us. These parts were laser cut straight from the sheet with the holes and external profiles programmed with our Radan sheet metal software. A quick barrel de-burr and the parts were ready for our customer.

Aluminium CNC punched disks

Here we have a batch of circular discs that have been CNC punched out from 3mm thick 5251 aluminium alloy. All the holes and internal cut-outs were produced with standard CNC punch tooling on our Trumpf 3000R CNC punch press. The outer circular profile was produced on the same machine as the last punching operation with a curved “banana” punch and die allowing the finished part to fall from the parent sheet of metal and into a collecting bin under the machine. A quick edge de-burring operation and they were ready for powder coating.

Galvanised steel sheet metal brackets

A more standard production job for us here at V&F is producing sheet metal work whether laser cut or CNC punched from galvanised steel sheet metal. These light fitting parts have been CNC punched, edge de-burred, CNC bent up and have a hank bush inserted.

For more free advice and prices on your specific sheet metal projects please don’t hesitate to contact us on 01489 577786 or send us your drawings or 3D CAD data to sales@vandf.co.uk and we will be happy to help you more you sheet metal projects forward.

CNC punched sheet metal work

Wednesday, March 16th, 2016

CNC punched aluminium front panels

Nice range of simple aluminium electronic front panels for professional audio equipment. With the large range of CNC punch tooling we have here most shapes and sizes of cut-out can be catered for without the need to purchase special CNC tooling. We have a list of all the CNC punch press tooling that you can specify when creating a new sheet metal design to make it easy for you to save money. If you are not sure you only have to call us and we will be happy to advise you on the best set of tooling to do the job. These front panels were CNC punched and had all external punched edges de-burred before they were wet spray painted and shipped. Sets of similar parts were all CNC punched on the same sheets to save material costs and keep the parts together in production.

CNC punched clamping bars

Small aluminium clamping bars used in electronics equipment. These sheet metal bars were CNC punched on our Trumpf 200 CNC punch press using standard tooling. The parts were punched down through a die and collected from the machine with no corner holding tags. The parts were then barrel de-burred to remove all the sharp edges and finally, using our Haeger inserter, had their flush head studs pressed in place. The Haeger inserter can also be used to insert hank bushes, self clinch nuts, tank bushes, stand-offs and special purpose fasteners.

CNC punched zintec plates

A simple 0.7mm thick zintec coated mild steel bracket blank produced on one of our CNC punch presses. The radiused corners being produce with our R2, R3, R4 and R5 combination punch tool. These parts are typical of the small sheet metal work that we CNC punch out all the time here at V and F Sheet Metal. If we don’t have quite the right tooling on the rack we can always look to laser cut the parts, so between both manufacturing processes we can cover all your sheet metal blank needs in ferrous and non-ferrous materials.

If you are looking for a supplier of sheet metal work then please give us a call on 01489 577786 or send your drawings to sales@vandf.co.uk and we will be happy to review them and produce some prices for manufacturing.

CNC punching sheet metal brackets

Here we have our Trumpf 200 CNC punch press punching out a thin gauge zinc coated mild steel (zintec) sheet metal bracket with many others from the same 2M x 1M sheet. You can see that the brackets has been spaced 5mm apart so that a standard slitting tool could CNC punch along the left hand and right hand of 2 parts at the same time, a technique known as common line cutting. This simple but effective technique helps us supply sheet metal blanks from the CNC punch press quicker and saves money when quoting for the parts.

This project was interesting in that we started producing the brackets on our Trumpf 3030 fibre laser and when we had other urgent jobs we simply swapped it to our Trumpf 200 CNC punch press which was more than capable of producing the parts.

Radan sheet metal software case study

Thursday, March 3rd, 2016

We are really pleased to have been chosen by Radan to be featured in a case study on the use of their software. We have been using Radan CAD/CAM software for over 16 years to help us produce sheet metal work from a range of machines. We use Radan software to produce 3D models from scratch and to read 3D models sent to us by our customers. We also use it to develop our 2D flat blanks which can be either CNC punched or laser cut with our Trumpf manufacturing equipment ready to be bent using a range of CNC press brakes.

We have always valued the support we get from the Radan team and the continual development in the software to support a range of new features in sheet metal manufacturing machines.

Folded sheet metal work

Folded sheet metal work produced here at V and F Sheet Metal

Folded mild steel brackets

Great example of simple mild steel channel brackets that have been CNC punched and then CNC bent using one of our Trumpf 7036 CNC press brakes. These sheet metal projects are typical of the folded work that we are involved with everyday of the week for our UK customer base. Many parts that we fold up have to meet tight tolerances, such as +/- 0.2mm and we can achieve that in thin gauges due to the accuracy of the blanks we can produce via CNC punching and laser cutting as well as the high quality CNC folding facilities we have within our company.

Folded aluminium sheet metal trays

CNC punched and CNC bent aluminium chassis trays are no problem for us. We have a range of standard CNC punch tooling that enables us to produce your electronics holes, cut-outs and profiles without the need for new tooling in the vast majority of cases. These chassis trays were produced with a protective plastic film on the outside and then treated with an Iridite NCP finish before sending to our customer. We are often asked to finish a sheet metal project be it powder coating, wet spray painting, anodising and Iriditing aluminium or zinc plating mild steel. We have a network of suppliers who can provide these finishes and offer design help for more complex parts to ensure there aren’t any problems when being treated.

Laser cut and folded mild steel brackets

These mild steel brackets were laser cut, folded on our Trumpf 7036 CNC press brake and formed with simple tooling we made up to go on our fly-presses. They show nicely the range of manufacturing techniques that can go into the simplest of sheet metal parts.

For more information on the range of bending / folding options we can offer you from the smallest stainless steel spring clip to 3M long folded sheet metal sections. Have a sheet metal work project that needs folding, please give us a call or send your drawings to sales@vandf.co.uk and we can offer you free advice if needed and quote options to see what will work best for you.

Laser cutting brass sheet metal

Thursday, February 25th, 2016

Removing brass scrap pieces

It’s not often that we get a laser cutting job that can really show off the ability of our Trumpf 3030 fibre laser cutting machine here at V and F Sheet Metal but here is one such sheet metal project. We were asked to cut 2 decorative brass fretwork panels and our laser cutting machine was perfect for the task. The brass panels were to be manufactured from 2.5mm thick brass sheet and laser cutting was no problem for us having a fibre rather than CO2 laser cutting machine. The Trumpf fibre laser cutter is able to cut up to 6mm thick brass sheet so this order was no problem.

Complete brass laser cut panels

I took the DXF files supplied by the customer and cleaned them up. They had various errors in them including lines upon lines, corners not joining in places and more importantly points where if we had followed the drawing the brass panel would have fallen into several parts. All the drawing was cleaned up using our Radan CAD/CAM sheet metal software and small changes were made to suit laser cutting. The “clean” file was then programmed for laser cutting and the 2 panels needed laid out on a single 2500mm x 1250mm sheet.

Laser cut brass sheet fine detail

With both parts laser cut and the sheet automatically cleared from the machine it was only left for us to remove the internal waste parts to reveal the finished brass fretwork panels.

Perhaps you have a brass sheet metal part that you didn’t realise could be laser cut with modern fibre laser technology, please give us a call on 01489 577786 or send us your drawings to sales@vandf.co.uk and we will be happy to help you and advise where you designs can be improved to save you money.

Folding sheet metal housings

Folding sheet metal housings from 0.9mm mild steel sheet metal

Our Safan e-Brake CNC press brake is more than capable of folding sheet metal work up to 3M long and with 100 tons of electric motive force you can see that these sheet metal housings were no problem. With each sheet metal housing having 8 full 90 degree bends to complete the enclosure to hold the electrical components for an emergency exit light. The order was for 500 housings and the blanks were produced on our Trumpf 200 CNC punch press to ensure they were precise and would produce an accurate component throughout the batch. The Safan e-Brake is fast, very quiet to operate and easy to program, making it the perfect machine for light sheet metal work batch production such as this.

Sheet metal housings such as these are our bread and butter and we are often found manufacturing sheet metal housings from special projects to repeating batches of 25 and 50 up to 500 like this and beyond when needed. Have a sheet metal housing and need a price, please don’t hesitate our engineering team and we will be happy to help you.
