I have an older Hitachi Seiki lathe thatís not cutting right. Over the weekend running some parts a wrong tool offset value was entered on a an X move. Instead of offsetting as a negitive number in a rush I entered a positive number and a 5/8 boring bar bumped the edge of the part, blew the carbide insert off, broke the insert seat and knocked the part out of the chuck jaws. Ever since then the machine will not cut well at all, excessive chatter and sounds like the cutting tool is beating the part to death rather than cutting.
The bump wasnít a rapid move, a spindle speed of 800RPM and a feed of 0.004. With all that said would the ďbumpĒ be enough to knock the turret out of alignment? How would one re-align the turret?
