CNC engraving and milling machine high-speed spindle bearing installation method, steps and precautions

CNC engraving and milling machine high-speed spindle bearing installation method, steps and precautions

1. First of all, we must ensure that the motor cooling cycle system of the engraving and milling machine works normally before starting the machine. Then turn on the spindle motor and use the spindle motor without cooling. The working environment temperature should not be higher than 30 °C. When the ambient temperature is higher than 30 °C, the air conditioner should be used, or the refrigerator should be used for forced cooling of the spindle motor.

2. It is necessary to review the parameters of the input starting point. It is strictly forbidden to strike or hit the rotor end of the spindle motor during the operation. The operator is required to pay attention to the Z-axis starting point when facing the knife to prevent misoperation. It is necessary to avoid damage to the bearings of the spindle motor caused by impacts and knives during operation. Once there is a knives phenomenon, stop immediately to prevent more damage to the bearings caused by high speed operation. Then, the running-in is started from a low speed, and the time is slightly longer than the normal running-in time until the motor runs smoothly and normal before starting work.

3. The spindle motor should be gradually warmed up according to the principle of running from low speed to high speed. When the motor reaches the required speed and the no-load operation is stable and the temperature is cooled, it can be processed to ensure better machining accuracy.

4. When planning the cutting path, it is necessary to ensure that the spindle motor is under reasonable force. The carving process should be carried out according to the principle of using the knife provided by the technical service personnel. Be sure to prevent the vertical knife from falling, and prohibit the spindle motor from overloading to ensure the normal service life of the spindle motor.

5, to use a dedicated engraving and milling machine spindle cold oil.

6. Generally, the spindle motor should be disassembled and reassembled for one year or so, which can ensure the bearing precision and prolong the service life. In order to ensure that the spindle motor can work normally, its assembly and assembly must be carried out by experienced professional operators, in a clean environment, and with appropriate tools. For the electric spindle that is not used temporarily, the residual water in the water chamber should be blown out with compressed air. The sleeve and the shaft hole of the shaft should be oiled and rustproof and placed in a cool and dry place.

The above is the high-speed spindle bearing installation method, steps and precautions of the CNC engraving and milling machine. The installation operation should be carried out strictly according to this operation!
