I had one aggravation using my Wen benchtop drill press. The depth stop was a knurled nut you spun up or down on a fine threaded post to set the depth you want your drill to stop at. Aggravating and slow to set.
I've made press button releases for a few other projects in the past (before I had a cnc), but thought I'd see if I could make the parts for a press button depth stop from aluminum on my Probotix CNC. Quick answer: Yes. Reality meant it took more than one try to learn the limits of what my CNC could handle. I made one out of HDPE (dense plastic) first.
No real challenge as HDPE cuts easily.
An aluminum version came next.
This one required learning the limits of my CNC and how to deal with them. An earlier version came out undersized thanks to deflection of my bit making full width cuts through the aluminum. Ramping down between cuts took the sharp tips off the bits I was using. This last one eliminated full width passes and ramping for a fairly accurate outcome. Clamping the parts securely down to be cut proved critical. Lowering feed speed, bit RPB, pass depth, stepover all proved necessary.
