I have an early 90 model Okuma Cadet LNC-8 lathe. In the middle of running parts I noticed it cut a huge chamfer on the ID of a part. Then one minute it didn’t cut it at all. Then another o-ring groove was cut incorrect in Z.
I checked backlash in Z and moving one direction with the machine in tenths two clicks on the hand wheel it moved .0002 before my interaprid .0001 indicator would move. Then in the other direction it took 7 clicks with the hand wheel to move .0002. So I wouldn’t think the Z axis bearings were bad. What could I check for regarding the encoder? Or any other suggestions anyone may have.
Thank you for any help in advance.
