Purpose and characteristics of the machine tool

1. Adopt the 2-axis CNC system with built-in PLC and LCD, which is produced by Siemens of Germany

2. Adopt the ball screw shaft of servo motor to drive the longitudinal movement of the work-table and the traverse movement of the grinding carriage.

3. This machine tool is applied to the grinding the components of solar energy industry and silicon single crystal rods, and it can be used to grind the external cylinders of 3inch~8inch rods.

4. Adopt the external grinder layout, and take the new peripheral grinding to the external cylinders of silicon single crystal rods with diamond parallel grinding wheels as a substitute for the traditional technology of rolling and grinding with facr parallel grinding wheels.

5. The direction of the grinding lines on the single crystal silicon external surface of the is normal to the axis and is consistent with the processing direction, so that in the slicing, no crack will occur with the peripheral circular arcs.

6. As the production rate of Φ300 ecternal diamond wheel peripheral grinding is greatly higher than that of samll grinding wheel rolling and grinding, the speed is increased by 3~5 times.

7. The headstock and tailstock are fixed with a purpose made four-jaw self-centering fixture which can retain 3in~8in squares. The maximum stroke of the tailstock sleeve can reach to 120mm. The length of workpiece varies within 100mm. The tailstock can be maintained fixed, and the fixture has high self-centering accuracy and is easy to operate.

8. The rotation speed variable frequency motor of the headstock adopts stepless speed regulation. The fixtures are equipped with special brackets for easy loading and unloding of workpieces. The grinding carriage has large feed grinding amount and high efficiency.
