1. High precision universal cylindrical grinding machine;
2. High precise alignment of spindle head and solid support ensure ideal machining results with various grinding processes;
3. Versatility due to table, headstock, and grinding headstock swivel;
4. Wide speed range of workpiece spindle;
5. Stable running without noise can be achieved because of adopting screw pump in hydraulic system;
6. High rotating precision and strong rigidity can be obtained by sleeve-type whole-tile moving hydraulic bare shaft system on the spinlde of wheel head;
7. Slideway is covered by the plastic so it can gain slow speed running and high immunity to vibration;
8. The models with MGB can be perform high precision semi automatic cutting, longitudinal grinding to make high precision parts by using limited stroke or controlled by process gauge in small batch or mass production;
9. For models with MGB, all grinding function and sequences of action during processing cycle are controlled by programmable logical controller (PLC);
10. Quality by CE certificate.
