·The working environment temperature of the spindle is usually -10~40.
·Before installing the first electric spindle to rotate the spindle head by hand, you should feel flexibility and no blockage.
P4 fully sealed angular joint bearings can extend the life of the spindle.
The longer the length, the greater the torque and the greater the power.
Careful assembly makes the spindle more precise.
The accuracy is 0.01mm, and the coaxial cable is less than 0.0025mm
1. Our main shaft uses 4 bearings.
2. Bearings are resistant to high temperature and low heat
3. The ball bearing has low friction, low noise and long service life.
·When the spindle is stored and transported, the bearing condition inside the high-speed grease will change, and the customer should run it at low speed for 30 minutes. Then increase slowly at a speed of 3000 rpm, running for 20 minutes each time. The spindle and inverter should work together. The specifications and parameter settings of the inverter match the spindle parameters.
·To connect the inverter main shaft, the three-phase inverter power cord should be welded to the plug 1 (U), 2 (V), 3 (W) pin, and the grounded pin 4. After turning on the power, observe whether the spindle rotation axis always shows the direction. If it is inconsistent, turn it off immediately, and replace the two wires of the three-phase power supply connected to the inverter and the spindle.
·Before using the spindle every day, it must run at low speed for 15-20 minutes. Clamp the cutter on the spindle, the chuck nut, chuck, and cutter must be clean enough. The shank inserted into the chuck must be larger than 15mm.
·During normal operation, the air-cooled spindle often has heating phenomenon. Please check frequently whether the air-cooled spindle box and air duct are blocked with dust. If it is blocked with dust, it should be cleaned in time.If it is not cleaned, it is easy to burn the spindle.
1. Different cooling methods: The water-cooled spindle motor uses water circulation to cool the heat generated after the spindle rotates at a high speed, and the spindle motor uses fan cooling for cooling.

2. Noise: The water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very large.

3. Life: water-cooled spindle motor should pay attention to maintenance, often change water or use industrial water cooler, air-cooled spindle fan mainly blows heat to the heat sink by wind to achieve cooling effect.

4. If you need to use metal, hardwood, granite, stone, you can choose metal mandrel. Metal mandrels are much better than wooden mandrels.
·The spindle frequency power supply is connected to the rated voltage, and the frequency should be consistent with the technical parameters of the electric spindle. The spindle speed can be adjusted to change the frequency, and the voltage changes in proportion.
·To replace the spindle bearing, some professional and technical personnel should be replaced. With special tools, the bearings should be cleaned thoroughly without removing the stator coil.
