Main Features

1) The side tiltable feed plate is applied in this machine. It

 can adjust the in/out degree of ball according to the dia-

meter of workpiece. Its useful to improve the movement of ball.

2) The close frame structure is used in the main machine. The box and the bed are made by special structure design and material treatment. Therefore, the machine has good rigidity, high efficiency, low noise and good anti-seismic.

3) The hydraulic loading system is controlled by a remote pressure regulating valve. The pressure of system can be adjusted by the remote valve.

4) The machine has spring bumper and eccentric load system.

5) The feed plate control system adopted AC frequency conversion technique.
