1. The motorized spindle and the inverter should be used together, and the specifications and parameter settings of the inverter should match the rated parameters of the motorized spindle. If the setting is incorrect, the electro-spindle will be burnt.
2. Before using the water-cooled electric spindle, the cooling circulation system must be guaranteed to work normally. It is strictly forbidden to use it without cooling. The cooling water volume is calculated at 1 liter/kW minute, and the minimum cooling water flow rate is not less than 5 liters/minute. Cooling water pipes and nozzles The connection must be reliable and not leaking.
3. The coolant must be clean, non-greasy, and the temperature should be controlled at 5-30°C. If the ambient temperature is higher than 30°C, the cooling medium must be forced to refrigerate. Precision processing machine tools require a constant temperature of 20±2°C for the coolant.
4. During the storage and transportation of the electric spindle, the state of the high-speed grease inside the bearing will change, and the customer should run-in at a low speed before using it. The running-in starts from the lowest speed of the electric spindle. After 30 minutes, the number is incremented by 3000 revolutions. Each gear runs for 20 minutes. If it is not run-in directly, it will start at high speed, which will cause abnormal noise, noise, heat and other phenomena, which will affect the service life of the bearing. The electro-spindle should be turned on (low speed) for 15-30 minutes at least within a week during long-term use and storage.
5. When clamping the tool on the electric spindle, the collet, nut, and inner taper hole must be cleaned to avoid affecting the accuracy. The tool holder must be greater than 15 mm when inserted into the collet.
6. The electric spindle must be preheated during daily processing. After the electric spindle reaches the processing speed, it will finish machining after 15-20 minutes of operation. It is advisable to stop the electric spindle for 2 hours every day to restore mechanical fatigue and prolong its service life.
7. It is strictly forbidden to knock the end cover of the electric spindle, and it is strictly forbidden to knock the collet and cutter head when unloading the tool. It is strictly forbidden to knock during transportation, storage and use, especially the shaft end.
The electro-spindle must run in the specified direction.
8. Please install the electric spindle according to the instructions of the spindle installation diagram.
9. The temperature of users who use water chillers for cooling must be controlled at 22-25°C.
10. Air-sealed electric spindle. The air source must pass through an oil-water separator and a filter drier. The air pressure is 0.2-0.25MPa, and the filtration accuracy is 5μm, otherwise the bearing will be damaged.
