GM Servo Compound Grinding Machine

Submicron Servo Turning & Grinding Compound

Turning / Grinding Compound: B-axis rotary table equipped with external / internal cylindrical grinding head and a tool holder. By rotating B-axis, these components can be switched at will, to fulfill turning & milling compound machining.
Grinding Fuction: by combining the X/Z linear axes and the B/C rotary axes, various grinding functions can be realized, including external / internal cylindrical grinding, conical grinding, thread grinding, groove grinding, and servo contour grinding.
Rotary Dressing: a rotary dresser is employed, paired with a high-rigidity diamond roll, to enable multiple types of grinding wheel dressing.
