Hi, I wonder if you kind souls will help out a New retired Chinese CNC user. I've bought an Aluminium Vacuum table which works fine for suction
but needs a light planing to get accuracy on the Z plane. What if any bit should I use to achieve this and what speeds etc.. I'm happy engraving acrylic and wood but have never attempted alloys. The CNC is a 3040 and works well on small projects for home use. It has a 200 Watt spindle with approx 12000 revs.
Thanks Fraxinus
