Non-Cogging Motor Improves Grinding

Mating a non-cogging motor with an ultra-precision air-bearing spindle enabled a micro-grinder spindle/indexing system for outside diameter (OD) grinding and profiling of parts with diameters as small as 25 microns. The non-cogging motor eliminated flat spots caused by conventional brushless motor cogging, while improving accuracy, repeatability, and surface finish. Read All
