Main configuration of machine tools
● The grinding wheel spindle and workpiece spindle are both mechanical spindles. The grinding wheel spindle is driven by a three-phase asynchronous motor, the workpiece spindle is driven by a servo motor, and the grinding wheel has a constant linear speed of 60m/s;
● The valve stem is clamped with a single cone spring clamp, the grinding wheel is fed and grinded quickly, and the grinding wheel is automatically trimmed and compensated automatically;
● The machine tool operates using the Japanese Mitsubishi human-machine interface, PLC and supporting servo motor, which can adjust parameters, feed speed, read shift output, cycle processing time and alarm information through the screen.
Functions and uses
Mainly used for grinding the inlet and exhaust valve cone surface of generator sets and marine engines.
