CNC punched sheet metal profiles
CNC punched profiles in plastic coated aluminium
Typical simple CNC punched component profile produced from aluminium alloy with a white plastic peelable film. The plastic helps to keep the component scratch free and clean from oil and finger marks in production. We only CNC program one component internal and external profile and then use our Radan programming software to multiply the components across the sheet. The edge tooling is used to common line cut (producing the right side of one component and the left side of another at the same time). The part are held in with an edge profile that has a 0.1mm tag in each corner which is easily broken off after CNC punching has taken place.
Sheet metal CNC punched profiles
This part also produced on the same sheet uses a 4 corner radius profile tool to produce a small corner rad in several places. With a Trumpf it’s easy for us to turn the radius tool to whichever angle we want and create the correct profile. This particular CNC tool has a R2, R3, R4 and R5 built into it making it very flexible for components with a variety of corner rad profiles. There is also a single D profile punched into the component, we have a range of single and double D tooling which can be specified in your sheet metal component designs for free, follow the link to our tooling pages Single D and Double D.
CNC punched 2 part nest
A recent project needed a small box and cover to be manufactured both from the same material and thickness. The ideal solution was to CNC punch them from the same sheet of metal as seen here. This has the advantage of using material with the same tensile strength enabling easier setting for us when CNC bending and punching the whole project to production at the same time. These were simple parts but sometimes when there are complex profiles one part can be nested within another, say inside an internal window or between two parts with a hollow profile. We are always looking for ways to reduce CNC punching time and materials used to help keep your part prices down.
