Processing Methods

Equipment Highlights

1. The bed is made of one-piece welding parts and the column is made of high-grade cast iron. The precision and stability are high. The Welds and castings are treated by second annealing and shot blasting to make the basic parts more stable and reliable.

2. The worktable is supported by high precision special turntable bearing, which is driven by servo motor and reducer to ensure the rotating accuracy and stability.

3. The angle between the grinding head and the worktable can be adjusted, and the angle can be detected conveniently. It can adapt to different continuous feed grinding modes.

4, equipped with strong magnetic table, and by the program control magnetic.

5, the z Axis uses the precision ball screw, collocates the stable reliable servo system, causes the up and down enters the knife to maintain the high accuracy and the high stability.
