CONFIGURATION

1. The longitudinal movement of the table driven by the blade pump, smooth operation, low noise, low temperature of the oil pool, the accuracy of the horizontal axis of the surface grinding machine grinding country standard (GB / T4022-1983).

2. Can be groove and flange side of the grinding.

3. Improved grinding head horizontal feed mechanism, both hydraulic automatic feed and manual feed, easy to operate.

4. Grinding head vertical movement has a fast lifting motor feed , but also with manual feed.

5. Grinding head motor and pump motors are used high-grade motor, electrical implementation of national safety standards.

6. The machine has the location where the digital display is installed.
