Cylindrical Grinding Machine

Model NO.:	M1320E / MB1320E / MS1320E / MBS1320E / M1332E / M

Product Description

Features:

1. Stable running without noise can be achieved because of adopting screw pump in hydraulic system.

2. High rotating precision and strong rigidity can be obtained by sleeve-type whole-tile moving hydraulic bare shaft system on the spindle of wheel head.

3. Slideway is covered by the plastic so it can gain slow speed running and high immunity to vibration.

4. The machine has high precision, reasonable integral layout, beautiful shape. Centeralized and imaginary operating lever are easy and safe for operating.

5. MB(semi-automatic)grinding machine can perform semi-automatic preci-sion cutting, longitudinal grinding to make high precision parts by using limited stroke or controlled by process gauge in small batch or mass production.

6. MB(semi-automatic) all grinding function and sequences of action during processing cycle are controlled by programmable logical controller(PLC)
