Hi everyone,
I've built myself a 5x10 cnc machine and I've been cutting some small detail projects in some formica. It's a very thin aluminum face with a cork backing like a laminate, typically used for cabinets. Anyways, the cuts are very small so I use a 1/16" end mill for the work. I managed to find a couple for sale from sherlinedirect who sell 1/6" bits with a 1/4" shank, but they're all upcut bits. I'm looking for anywhere I can find a downcut bit. Using the upcut bit, I'm getting a lot of pull on the material. I can't seem to get a clean edge on the cuts using the upcut, even when putting the good side facing down.
Any help is greatly appreciated. Thanks.
