Mori Seiki NL3000 with Radial and Axial Shaft Movement



CHALLENGE

Our customer was having difficulty holding tolerances and experienced chatter marks on their parts. After receiving the spindle our incoming evaluation did show excessive axial movement and end play. The bearings were contaminated which can cause looseness in the spindle assembly due to wear on the rolling elements.

SOLUTION

Clean, inspect overall dimensions. Replace bearings, o-rings and screws. Adjust preload, balance, assemble and break in. Final quality control inspection.
