Oh that's pretty neat! I can add it to the long list of projects lol...

Enough of this manual lathe nonsense, today I fired up the CNC at last and made the top plate for the new Z-axis.

First fixture:




Roughing pass (6mm 3 flute roughing bit, 8mm depth of cut with 1mm axial engagement, 12,000rpm and 1,500mm/min




Finished top side (3 flute, full depth pass 16mm skimming 0.1mm off each pass with a repeat finish pass, 12,000rpm 1000mm/min and a chamfer pass):




Then I drilled two holes for 6mm dowels to align with machine axis, and probed for zero:




Backside ops done:




Finished part with seals and bearing:
