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