Equipment Highlights

Equipment Highlights

1. This machine adopts IN-FEED feed grinding theory. The servo motor drives the grinding wheel to move in the vertical direction. The lower disc is driven by servo and synchronous belt. It can rotate in the same direction or opposite direction with the grinding wheel according to the requirements of the process.

2. The machine adopts precision cross roller bearing deep groove ball bearing to support the workpiece spindle, with high rigidity and precision. Vacuum adsorption is used to clamp the tooling or workpiece.

3. The grinding head uses an electric spindle to drive the grinding wheel to rotate, and uses a classic screw wire servo motor to drive the vertical feed; the Z axis uses high-precision grating closed-loop feedback to control the Z axis feed accuracy.

4, the use of dual-head measuring instrument Marpos D-Model 2Unimar, can achieve precision control of workpiece grinding thickness size error.

5. Adopt interactive man-machine interface (touch screen), precise control and simple use.
