Characteristics of Precision High Speed Motor for Electric Spindle

時(shí)間:2019/5/27 9:20:06
The motorized spindle is a precision high-speed motor, which has the following main characteristics:



1. All bearings adopt C-class high-speed angular contact ball bearings with preload on the axis to improve the support stiffness and grinding accuracy of the spindle under high-speed rotation.



2. Precision steel ball holder is used to ensure the rotation accuracy of motorized spindle in high speed grinding.



3. Electric spindle is usually lubricated by 5 # spindle oil mist.



4. Coolant circulating cooling is used for cooling the motor spindle housing to reduce the heating caused by high-speed rotation and reduce the temperature rise.



Instructions



1. When using, the oil pipe must be connected first, so that the motorized spindle can connect the oil pipe first and then start the safety.

Pipe and tubing should not be misconnected during installation. The left and right sides of the spindle are water pipes, and the middle is oil pipes. Oil lubrication of spindle of NC drilling machine does not adopt the following methods. 2. Oil mist pipeline should be connected before use, and oil mist pipeline joint should be cleaned. Prevent the bearing from burning out due to the entry of dirt. Then supply lubricating oil mist to the motorized spindle, so that the motorized spindle can start only after a slight oil mist leaks out from the front end of the motorized spindle. Oil mist lubrication is recommended to use No. 5 spindle oil to adjust the oil intake of 20-30 drops/min, and often check to meet the requirements, so as not to cut off oil and cause damage to the spindle.



3. Before driving, rotate the spindle by hand. If there is a sense of impediment and inflexibility, then troubleshooting should be done and the spindle rotation square a should be checked. If the spindle rotation is counter-clockwise, the power wiring should be changed to make it consistent.



4. The motorized spindle must stop turning completely before it can close the oil mist. Under normal operation conditions, it can generally run continuously for a long time, but the start-up should not be too frequent. Before use, it is necessary to check whether the grinding wheel connecting rod is coaxial. If the different axes exceed 0.03 mm, the grinding wheel connecting rod should be replaced, otherwise the electric spindle will be damaged and the workpiece will not be worn well. When grinding, attention should be paid not to impact, and grinding should be carried out after correction.
