Main configuration of machine
▶An electric spindle is adopted for the grinding wheel spindle, with Italian Balance built in for online dynamic balance. A mechanical spindle is adopted for the collet spindle, which is driven by a servo motor, and the dressing spindle is equipped with an AE sensor;
▶Single cone collet used to clamp the valve stem, ceramic CBN grinding wheel quick feed and to grinding, and ordinary silicon carbide grinding wheels can be also used;
▶Siemens CNC system is adopted for the operation of the machine, which can adjust the parameters, feed speed, read the shift output, cycle processing time and alarm information readed through the screen.
