◆ Stable running without noise can be achieved because of adopting screw pump in hydraulic system.
◆ 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.
◆ Slideway is covered by the plastic so it can gain slow speed running and high immunity to vibration.
◆ The machine has high precision, reasonable integral layout,beautiful shape. centeralized and imaginary operating lever are easy and safe for operating.
◆ 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.
◆ MB(semi-automatic) all grinding function and sequences of action during processing cycle are controlled by programmable logical controller(PLC)
