Hey guys i need some ideas here. I got my tormach in September Ive been having allot of chatter issues with the machine but only in the x-axis. The machine has a brand new spindle as of last week (crack developed in the original spindle and Tormach quickly replaced it). I ive noticed the issue mostly when milling square profiles with the waterline roughing opp in sprut cam. I am using a 1/2 3 flute carbide cutter .625 flute lengh (1/2 depth of cut and .125 stopover about 25 ipm).
The cutter does not make a peep in the Y axis and it rounds the corner to the x axis side and it starts squealing then turns back to the y axis and the chatter stops again.
I talked to Tormach and they suggested I adjust the X axis gib so my indicator matched up with read out (ended up loosening the gib 2 turns temporarily fixed the problem has about .0005 back lash when changing directions) I also checked the Y axis that seemed fine.
My hunch is that one of the trust bearings on my stepper motor is loose or there is something loose on the head. Does anyone have any suggestions as to how to diagnose this issue.?
