Product Name: Universal Cylindrical Grinding Machine GE/GBE/GSE/GBSE Series
Performance:
· Universal cylindrical grinding machine;
· Precise alignment of spindle head and solid support ensure ideal machining results with various grinding processes;
· Versatility due to table, headstock, and grinding headstock swivel;
· Wide speed range of workpiece spindle of the Grinding Machine
· 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 models with GB can be perform semi automatic precision cutting, longitudinal grinding to make high precision parts by using limited stroke or controlled by process gauge in small batch or mass production;
· For models with GB, all grinding function and sequences of action during processing cycle are controlled by programmable logical controller (PLC);
Standard Accessories:
· Balancing arbor
· Balancing steady for grinding wheel
· 3-jaw chuck
· Internal grinding attachment
· Grinding wheel tray
· Coolant tank
· Stand grinding wheel dresser
Optional Accessories:
· Close centre rest
· Open centre rest
· 4-jaw chuck
· Automatic measure indicator (only for models with GB)
