High-speed micro machining can be done on a normal machining center, eliminating the need of expensive high-speed machine.
Extended tool life with minimal thermal displacement
High speed rotation of the machine spindle generates heat, causing spindle expansion and Z-axial displacement. This displacement results in dimension defects of precision molds or tool breakage in micro machining.
The Air Turbine Spindle utilizes air for both driving and cooling the spindle simultaneously, thus the Z-axis displacement is eliminated.
Outstanding 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.
