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.

material, cutting conditions and cutting tools
Automatic Tool Change
ATC type is available by supplying air via
a stop block to enhance productivity with
unmanned operation.
Air Pressure: 90 PSI
Air Consumption: 7 CFM
Minimized Spindle Expansion
Air turbine drive prevents thermal expansion of the spindle,
which is essential for high accuracy micro-machining.
