Hi Ian
What taper is in the quill ? ie what capacity .
Nobby

Hi
When i used to set the cnc machines I Know its old hat now But i used a 5mm setting peice not my best slips . using electronic hand Wheel wind the quill down carefully take a light touch . go to controller Datum set z + 5 . As martin says
Always s think in terms which direction the cutter is moving z- x+ y- etc . drifting away a bit wire eroders you can program the bottom different to the top say for backing of dies
  I would have thought the knee up on a milling machine would enable the slot drill / cutter  to take another 
peck/cut  therefor Z minus .  I have my flack jacket on ready for replies

Hi Guys
It puzzles me how you can grind a rake angle on linisher belt say on an 1/2" square tool bit . ?

Nobby

I would have thought that the edge of the belt would wear very quickly .

But I notice in No. 2 photo . there is a large gap between the head and the stop on the pillar . elf and safety . slide it back under and lock in place . if you swung the head round at the moment the head would drop and my do some damage or injury .
