Main Feature

● The machine adopts IN-FEED grinding theory, the servo motor drives the grinding wheel to move in the vertical direction, the lower disc is driven by the servo and synchronous belt, it can rotate with the grinding wheel in the same direction or in the opposite direction according to the process requirement.

● The machine adopts precision cross roller bearing + deep groove ball bearing to support the spindle of workpiece, which is rigid and high precision, and adopts vacuum adsorption to clamp the tooling or workpiece.

● The grinding head adopts the electric spindle to drive the grinding wheel to rotate, adopts the classical way of screw rod + line rail + servo motor to drive the vertical feed, and uses the high-precision grating closed-loop feedback to control the Z-axis feed precision.

● Using double-probe measuring instrument mabis D-Model + 2Unimar, the error of grinding thickness can be controlled accurately.

● The use of interactive man-machine interface (touch screen) , accurate control, easy to use.
