Hi all,
I have chattering problem in HL-4 CNC lathe and vibration sound is horrible. While grooving it seems like whole machine is vibrating. We tried to fix this problem by doing number of maitainence works or part replacement but problem still occur.
We change the new spindle, new chuck and look for any possible cause in turret but have no idea what makes it chattering. I believe its in turrets but no idea where and how to solve it. Do any body have any idea ? thanks
