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.

Recommended Clamping Range

Minimized Spindle Expansion Air turbine drive prevents thermal expansion of the spindle, which is essential for high accuracy micro-machining.
