CNC Machining Center V850 equipment operators must strictly abide by the operating procedures and daily protection guidelines. The level of skill and professional quality of the operators is the key to determining whether the equipment can maintain a normal operating state. When the machine tool breaks down, the operator should pay attention to keep the site, and explain the situation before and after the fault to the repairer in order to facilitate the analysis and diagnosis of the cause of the fault, and remove it in time.
The heating of the CNC machining center is common, and the common problem is the heating of the spindle. The analysis and processing of this are as follows:
1. Excessive pre-tightening force of the spindle bearing causes excessive friction when the spindle rotates, causing the spindle temperature to rise sharply. It can be eliminated by re-adjusting the preload of the spindle bearing.
2. Grinding or damage to the spindle bearing will also cause excessive friction when the spindle rotates, causing the spindle temperature to rise sharply. It can be ruled out by replacing the new bearing. CNC machine tool.png
3. Dirty or impurities in the spindle lubricating oil will also cause excessive resistance when the spindle rotates and cause the spindle temperature to rise. Eliminate it by cleaning the spindle box and re-changing the oil.
4. Exhaustion of the lubricating grease or too much lubricating grease on the spindle bearing will also cause excessive resistance and friction when the spindle rotates, and cause the temperature of the spindle to rise. Eliminate by reapplying grease.
