Main configuration of machine tool
▶An electric spindle is adopted for the grinding wheel spindle, so online dynamic balancing function with can be built in. A mechanical spindle driven by a servo motor is adopted for the collet spindle;
▶The valve head is clamped by cored fixture, stem auxiliary support. Quickly feed the grinding wheel to completely grinding the valve groove and TIP end face at same in once;
▶Due to the adoption of Siemens CNC system and domestic GSK dedicated grinding CNC system, parameters and feed speed can be adjusted through the screen, with the output per shift, processing time in a cycle and alarm information read.
