MK8320CNC-550C (full protection) CNC high-speed (follow-up) camshaft grinder

Main functional features:

1. It adopts the special control system of grinding machine, three-axis AC servo motor control, two-axis imported high-precision ball screw, and imported bearing support; The C-type head frame adopts the precision electric spindle manufactured by 1.2KW Tebel, the D-type head frame adopts the torque servo motor manufactured by 1.2KW Tebel, and the electrical control is Schneider Electric. The machine tool has the function of automatic correction and compensation of grinding wheel, and measures such as safety emergency retreat protection in special cases.

2. This machine tool has the advantages of high repeated positioning accuracy, strong processing flexibility, good follow-up grinding quality, high efficiency, simple operation, easy learning, easy to realize automatic production, and multiple machining by one person. It is widely applicable to batch non-circular grinding of camshaft parts, non-circular surface, eccentric circle and other parts.
