Main features of machine tools
1. The main shaft bearing adopts the combination of double row short cylindrical roller bearing and angular contact bearing, which is preloaded with constant force, and the rigidity of the main shaft is good
2. The feed and compensation are realized by AC servo motor and ball screw driven by one-stage low backlash deceleration. The feed and compensation are accurate
3. The workpiece is brought in by the rotation of the feeding disc, so that the workpiece can pass between the two grinding wheels, that is, one grinding is completed.
4. The forward and backward motion guide rail pairs of the two grinding wheels are "cross" rolling guide rail pairs, with good support rigidity and high response accuracy
5. The wheel dressing adopts the form of swing arm two-point one-time dressing, which is reasonable in structure and easy to obtain the ideal shape of the wheel
6. The 90 ° rotary operation box is equipped with a 10 inch color touch screen, which is easy to operate
7. Differential grinding can be realized, and the protective cover of the grinding wheel can be opened electrically.
