A fellow Finnish cnc'er "JHQ" started this project a few years ago, but as he now has a 5000 kg professional cnc-lathe and his own company, he hasn't had time/money to complete this project.

Rigid Tapping

We've mounted a 500 cpr encoder on the spindle-motor which means it's possible to do rigid tapping. Above some spot-drilling, then a 2.5 mm drill, and then an M3 tap at 500 RPM and 0.5 mm Z-feed per revolution. Below the same thing but with a 5 mm drill and an M6 tap (1 mm [...]
