1. Magnetic force produced by high energy materials, no time limit, no energy consumption, no heat, environmental safety, simple assembling.

2. Strong attraction, magnetic force can be superimposed according to contact area increased,it can be used for strong milling & drilling.

3. The surface with big rigidity, good stability does not produce distortion, which can realize precision machining.

4. Simple mechanical switch, do not need power supply, avoid disappeared as suddenly loses power and make the magnetic workpiece falls off.

5. Simple quick replacement of the clamping workpiece,shorten clamp time,to realize five surface processing,improve work efficiency by 80%.

6. It could meet the milling requirements on the direction of horizontal XY.
