I collided (a soft collision) my threading tool with my tailstock live center.
I checked the turret alignment(it's ok), checked for taper machining(it's ok) and finally I checked the ''main spindle - tailstock alignment (that is not ok)
I read the ''installation and maintenance instruction manual'' and the procedure to align the tailstock is not very clear. I guess the Korean to English translation isn't good. Though I'm bilingual, I don't understand the instructions... even the French ones !
Can anyone help me ?
