Hi Rishi,

1. Are you sure your dialing numbers are correct? They look absolutely absurd to me (Tolerances are much tighter on all CNC machines- it should be 0.004 or 0.005, not 0.11 or 0.2)
2. Check your turret. If the turret is damaged or misaligned you might see results like this. Try moving the 40 boring bar to the 32/25 boring bar location and see if this changes your results.
3. Check which area of your Z travel you are working on. Sometimes one part of the guideway is damaged/worn out and if this is the case the results will vary. How old is your machine?
4. Jyothi tech guys normally know their work- we have a VMC850 and they have been very supportive. Do try calling in a different service engineer if the current one is unable to help.

I would suggest posting your requests with a better subject in order to get better responses from the forum

Best of luck
