Quality Assurance


Precision of headstocks for both lathe and machining center, spindle, and key components must pass strict tolerance specified on blueprints and also be inspected and checked by ZEISS CMM.

Laser interferometry is applied to measure accuracy and calibrate positioning errors for each machine under production. In addition, a state-of-the-art Renishaw ball bar system is applied to check three-dimensional squareness as well as to optimize motion servo control tuning. Only machine with circularity variation value within quality control standards is allowed to be delivered to customers.
