direct-driven high-precision hydrostatic turntable
Category: Product Center
Keywords: Yuhuan
Main Feature
1. High rotary accuracy: the roundness and flatness of the workpiece are better.
2. High positioning accuracy: direct drive torque motor + high precision grating.
3. The patent technology of hydrostatic bearing: never wear, the precision of machine tool is kept for a long time.
