I’ve had some 2mm sheet stainless steel laser cut, and need to clean up the edges and countersink a number of screw holes.
Cleaning up the rough edges I think is basically a case of filing and grinding/sanding.. Was thinking get the worst off with a file and then flap disc on a grinder? Though I’m open to other suggestions… (I assume there are flap discs with the grinders?)
Countersinking the screw holes - do we have suitable countersink bits in the metal shop? The piece basically looks like a large picture frame (circa 450x900mm) and the holes are around the perimeter.
As David pointed out I think a couple of passess with the deburring tool should do the trick.
And yes we have hole deburrers too!
A laser cut part is usually almost burr-free right out of the machine, so the use of a grinder and flappy disk shouldn’t be needed, but if you do want to go down that route, then we have that too.
In 2 mm thickness I would say be careful or you risk enlarging the holes too much.
What diameter are the holes?
A good trick is to do it on the pillar drill, you can do the first hole kind of free hand, then once you get the desired result, you can set up the depth stop and do them all the same.
Remember that because your material is that thin, you will need clearance on the other side, so be mindful with the set-up
