1. The center adopts the combination of the precise deep groove ball bearings, thrust ball bearings and needle roller bearings. 2. It is applicable to the medium speed precise processing of medium-load for CNC lathes.

3. The prolonged mandrel can improve the cutting performance and reduce vibration.

4. The center is made of alloy tool steel and its hardness after being heat treated could reach HRC 55-60. It is thus has high steel performance and high wear resistance.

5. The anti-dust seal on the front can prevent the cutting fluid and dust from entering into the bearings so as to prolong its service life.
