The spindle motor is an important part of the woodworking engraving machine, and it is also one of the more easily damaged parts. Generally, maintenance measures should be taken to ensure its normal operation and prolong its service life. Based on the actual situation, Jinan Pioneers Technology Co., Ltd summarized the maintenance methods of the spindle motor for your reference and study:
1. It is most important to read the relevant manual of the spindle motor carefully, master its operating requirements, and use the spindle motor according to the specifications.
2. It is necessary to establish a sense of care. For the spindle motor, the realization of the sense of care is to develop the habit of "clean up the spindle motor as soon as the work is completed"! If you develop this habit, the most important maintenance of the spindle motor is done. Up.
3. Keep the air entering the electric shaft dry and clean.
4. Remove the electric spindle from the machine tool, use the air pipe to blow out the residual water in the cooling cavity of the electric spindle, keep the interior clean, and do not have residues to avoid rust and block the water hole; short-term use, the appearance of the electric spindle should be coated Rust oil. Protect the shaft end and store it in a dry place.
5. The main shaft of the engraving machine that has not been used for a long time should be oil sealed. When starting, in addition to washing off the surface anti-rust oil with gasoline, the following work should be done:
1. Spray oil for 3-5 minutes, turn the shaft by hand, no blockage
2. Use a megohmmeter to test the insulation to the ground, generally ≥10 megohms
3. After turning on the power, first run at 1/3 rated speed for 1 hour, when there is no abnormal phenomenon, run at 1/2 rated speed for 1 hour, and then run at rated speed for 1 hour
4. During high-speed grinding, precision steel balls are used to maintain the rotation accuracy of the electric shaft.
5. The electric spindle can use high-speed grease and oil mist lubrication according to different speeds.
6. Use the coolant circulation method to eliminate the temperature rise caused by the high-speed rotation of the electric shaft
