Stainless Steel Guide Plate
Recently at V and F Sheet Metal we were asked to make a guide plate with tapped holes and I thought this would make an interesting topic for discussion. As with any project the initial phase of manufacturing starts with a clear and concise drawing. This should provide exact dimensions and if required precise position of holes and slots. With this particular design I was able to program the part within 10 minutes using Radan software. This batch of 50 guide plates were then manufactured from 2.5mm thick 304 stainless on the Trumpf 3000 machine.
A couple of the photos here show the sheet on the punching machine and illustrate a number of useful points which may not always be obvious to the customer. Firstly if you look carefully at the image of the CNC punching the guide plate, it is possible to see that at the back of the machine I turned the last two rows of plates to achieve the maximum number of components from the sheet. The nest diagram reveals this clearly and shows the small amount of waste material that will be left at the end of production. Secondly, although not obvious from the photos, this job actually made use of an off cut of material from a previous job, again allowing me to reduce the cost to the customer. In addition there was no need for special tooling as we have an extensive tool library at V and F Sheet Metal. Another money saving feature.
Finally I thought it was worth drawing your attention to the tapped holes on these guide plates. The Trumpf 3000 is equipped with a number of tapping tools and an M4 tap was used on these guide plates to produce a strong, clean thread within the material. It is an efficient process and cheaper than the traditional tapped cutting of threads which produces swarf, which must then be removed from the underneath the machine.
Hopefully you have found this useful and if you think V and F Sheet Metal can help you then please give us a call on 01489 577786 or email today at firstname.lastname@example.org. We look forward to hearing from you!
