1. The working environment temperature is usually 10 ℃ and 40 ℃
2. Motorized spindle and frequency converter, it is strictly prohibited to use directly connected to the electricity grid, so as not to burn out motorized spindle
3. Motorized spindle shall be marked according to the motor direction of rotation, it is forbidden to change to use before starting motor, should point frequency converter, observe its direction of rotation, such as the direction of rotation error, should immediately stop, can change the frequency converter set the direction of rotation or switch inverter U, V, W wiring terminal on any two of the wiring
4. Motorized spindle must not exceed the highest speed run, but allow speed in running.To extend the service life of motorized spindle and precision shaft, electric spindle after the replacement of bearing should be split 4 files within the speed range, respectively run 1 hours later, a total of 4 hours, then promoted to the highest speed, avoid direct high-speed operation and shorten the service life of the bearing
5. Water-cooled electric spindle should be carried out by circulating cooling liquid cooling, cooling water press 1 liter/kw. Minutes, cooling water flow rate lowest not less than 5 litres/minute, cooling water requires the use of single tank and add preservatives (coolant emulsion may be adopted or oil).If Shared with cutting fluid, it must be filtered cutting fluid, or motorized spindle cooling pipe Louis blocked, leading to damage of motorized spindle
6. Motorized spindle in the collet chuck, should remove hole in rotor shaft, screw taper hole and collet chuck away surface impurities, lest affect accuracy, collet chuck when installation should be equipped with tools, in order to avoid damage to chuck, no overexert when clamping, so as to avoid damage to the spindle
7. Abnormal sound or vibration in the operation of the motor particularly big, should stop check
8. Motorized spindle use after a period of time, such as special big vibration and noise, should find a professional repair spindle bearing replacement
9. Do not allow the force on the shaft end brake in any mechanical way
10. Motorized spindle downtime, should first turn off the power supply, to halt completely before closing the pump or fan
11. Motorized spindle deposit or stopped after three months, must be available to replace oil, otherwise will influence the spindle longevity
12. Motorized spindle are precision products, transportation, storage and use of it is strictly prohibited to knock against, special attention should be paid to the shaft extension end
13. Motorized spindle is abnormal, should by professional maintenance staff maintenance
