Main application: Wood, Aluminum, Stone, metal, glass, PVC industry Structural features : High-speed electric main bearings used in all C class high-speed angular contact ball bearings, axial pre-load feature, improved support stiffness and live spindle grinding accuracy under high-speed rotation. Spindle speed according to different uses can be high-speed grease and oil mist lubrication two ways. Spindle speed rotation temperature rise caused by the use of coolant circulation system d. Care and maintenance : Spindle frequency power supply connected rated voltage, frequency should be consistent with the technical parameters of the electro-spindle, spindle speed can be adjusted to change the frequency, and voltage is proportional to the change. Spindle being not used, the application of compressed air to blow the pipes static coolant. To prevent rust, clogging water holes. Spindle appearance should be oiled. Plus the shaft protection device, put in a dry place. To replace the spindle bearings, certain p
