1. Structural features

1) High speed electric main bearing all adopt the Ceramic bearing, axis sets of loading, Improve spindle in the high-speed rotation supporting stiffness and precision grinding.

2) Before driving, rotation of the shaft by hand.Spindle high speed rotation caused by temperature rise, use of cooling liquid circulating system to eliminate.

 

2. Maintenance and Service

1) Motorized spindle by medium frequency power supply rated voltage, frequency should be consistent with electric spindle technology parameters, motorized spindle rotational speed can change the frequency to adjust, also directly proportional voltage change.

2) When the spindle is temporarily not in use, should use compressed air to blow the coolant water,to avoid rusting, plug the hole. Spindle surface should be coated with anti rust oil. The shaft end protecting device, placed in dry place.

3) If replacement the spindle of bearings, best professional and technical personnel from the replacement. Use special tools, stator coil does not to be removed
