Study on Super-Precision Grinding Processing to the Spindle with CBN Slipstone

Abstract:

The spindle is an important part of twistering and winding in spinning frame. The spindle blade is the key element of spindle. As the development of hi-speed spindles, grinding accuracy and surface quality are greatly requested for the bearing class surface of the spindle. In the paper, an idea is presented to adopt super-precision grinding to machine the spindle blade. Throughing analyzing and discussing the super-precision grinding principle, A super-precision grinder was designed. A comparative test is made to investigate the differences between advanced CBN slipstone and ordinary abrasive corundum in performance. As a result, the surface roughness of the spindle blade which has been manufactured on the new grinder has reduced to Ra 0.01μm. The productivity of the new machine increases by 15 times.
