Here’s my second go around with aluminum engraving. Happy with it except the cheap vee bits I bought wore down and I had to reset the Z a couple times during the run. I’m going to order a couple good bits that “I hope” will last. Also, does anybody know where to get good quality short drill bits? I need to drill out or at least center a starter hole for drilling the pots and foot switches on the enclosure. Any suggestions much appreciated.
What was the angle of cut on the v-bits? depending on the angle, you may want to go to a more “shallow” angle so the engraver is more blunt. It’ll make it easier to do the characters in a single pass instead of multiple passes. a 60 degree, 90 degree, or even wider angle might be in order here, and then you set it up for v-bit engraving in Carbide Create instead of a regular path-trace.
Hello all, I am new to all this CNC stuff, what bits is everybody using on aliminium, i want to cut some and engrave on 1/4 and less aliminium, would prefer cheap ones tell I get the hang on it and ang suggestion on depth and speeds.
Thanks in advance for your help
You only need a few thousandths (.002" works for me) of depth per pass or you will certainly break the tip. It’ll still sort of engrave, but it’ll be pretty rough. If you want to do letters that are formed from more than lines, use a ball end endmill, but this limits how small you can make the letters.
