 Surface Grinding Machine

The surface grinding machine features a durable structure, excellent rigidity, a streamlined appearance and easy operation. Horizontal table movement is used to achieve mechanical transmission as well as manual transmission. A variety of flat grinding wheels are available, as are modifications to other grinding wheels for complex surface grinding applications. Depending on customer needs, a permanent magnet sucker or electromagnetic sucker is available for application.
