AIR POWER SPINDLE OVERVIEW
AIR POWER SPINDLE
High-speed micro-machining can be done on a normal machining center, eliminating the need of an expensive high-speed machine.

Dynamic Runout Accuracy Most problems associated with micro-machining are caused by poor dynamic runout of a machine spindle. We have established a runout measuring system that can detect spindle movement during rotation at high speed and achieved the best dynamic runout accuracy.
