1. The high-speed electric main bearings adopt C-class high-speed angular contact ball bearings, and the axial direction is preloaded to improve the support stiffness and grinding precision of the main shaft under high-speed rotation.
2. The electric spindle can be used in high speed grease and oil mist lubrication for different speed applications.
3. The temperature rise caused by the high-speed rotation of the electric spindle is eliminated by the coolant circulation system.
