The importance of CNC motorized spindle 1. High speed CNC must first verify the parameters of the input tool starting point. It is strictly forbidden to knock or impact the rotor end of the spindle motor during operation. The operator is required to pay attention to the starting point of z-axis during tool setting to prevent misoperation. It is necessary to avoid the damage to the bearing of spindle motor caused by collision and knife binding during operation. Once there is knife binding phenomenon, stop the machine immediately, so as to prevent the bearing from being damaged by high-speed operation. Then, start running in from low speed, the time is slightly longer than normal running in time, until the motor runs smoothly and normally.
- The high-speed CNC should ensure that the cooling circulation system of the engraving and milling machine motor works normally before starting up and using. Then turn on the spindle motor. It is forbidden to use the spindle motor without cooling. The working environment temperature should not be higher than 30 ℃. When the ambient temperature is higher than 30 ℃, air conditioner or refrigerator should be used for forced cooling of spindle motor.
- According to the principle of running from low speed to high speed, the spindle motor should be preheated step by step. When the motor reaches the required speed, the no-load operation is stable, and the temperature is cooled, then the processing can be carried out. Only in this way can the better machining accuracy be ensured.
- When planning the tool path, it is necessary to ensure that the force of the spindle motor is reasonable, and the engraving process should be carried out according to the knife principle provided by the technical service personnel. It is necessary to prevent the vertical cutting tool and prohibit the spindle motor from overload operation, so as to ensure the normal service life of the spindle motor.
- Generally, the spindle motor should be disassembled, cleaned and reassembled for use after running for about one year, so as to ensure the bearing accuracy and prolong the service life. In order to ensure the normal and good work of the spindle motor, its assembly must be carried out by experienced professional operators in a clean and clean environment, as well as using appropriate tools. Do not knock at random. For the temporarily unused motorized spindle, the residual water in the water chamber shall be blown out with compressed air, and the sleeve and shaft head shaft hole shall be oiled for rust prevention and placed in a cool and dry place.
