The electric spindle is a precision high speed motor with the following main features :
 1. The bearings all adopt C -class high-speed angular contact ball bearings, and the axial direction is preloaded to improve the bearing rigidity and grinding precision of the spindle under high-speed rotation.
2 , the use of precision steel ball retainer to ensure the rotation accuracy of the electric spindle during high-speed grinding.
3 , the electric spindle is generally lubricated with 5# spindle oil mist.
4. The cooling of the electric spindle housing is cooled by the cooling liquid circulation to reduce the heat generated by the high-speed rotation and reduce the temperature rise.
   Instructions for use       Â
  1. When using, firstly, the oil pipe must be connected first, so that the electric spindle can be started after the oil pipe is connected first.
The water pipe and the oil pipe cannot be connected incorrectly when installed. The left and right sides of the main shaft are water pipes, and the middle is a oil pipe. The following methods are not used for grease lubrication of CNC drilling machine spindles. ( see Figure 1 for details )
                        Â
2. When using, the oil mist pipe should be connected first, and the oil mist pipe joint should be cleaned. Prevents the ingress of dirt and causes the bearing to burn out. Then, the lubricating oil mist is supplied to the electric spindle, so that the electric spindle can be started after the oil mist is discharged from the front end of the electric spindle. The oil mist lubrication is recommended to use the No. 5 spindle oil to adjust the oil intake amount to 20-30 drops / min, and often check. Should meet the requirements to avoid oil breakage and damage to the spindle.
3, before driving, by hand rotation of the shaft, if blocking is not flexible feeling, and troubleshooting should check a direction of rotation of the spindle, the spindle end should see if the counter-clockwise direction does not match the power wiring should be changed, so that Match.
4. The electric spindle must be turned off after the spindle has completely stopped rotating. Under normal operation, it can generally run continuously for a long time, but the start should not be too frequent.
5 must be checked before using the wheel lever is connected coaxially, such as more than 0.03 mm different axes of the grinding wheel should be replaced connecting rod, or both spindle damage, but not grinding the workpiece. Be careful not to bump when grinding, and then grind it after correction.
     Maintenance and maintenance
  1. The rated voltage of the intermediate frequency power supply connected to the electric spindle should be consistent with the technical parameters of the electric spindle. The speed of the electric spindle can be adjusted by changing the frequency, and the voltage is also proportional to the change.
2. During the use, avoid accidental impact on the end of the shaft of the electric spindle and the workpiece.
3 , the used electric spindle is temporarily not used, use compressed air to blow the coolant inside the water pipe, so as not to avoid
Rusty, blocking the water hole. The outer surface of the electric spindle should be coated with anti-rust oil, and the shaft end should be protected by a protective device and stored in a dry place.
4 should try to reduce the air run and improve the service life.
5. If the electric spindle needs to be replaced, it should be replaced by a certain professional technician. Supporting special tools, should be thoroughly cleaned when replacing bearings, stator coils do not have to be removed
