Size: 100x300mm (diameter of middle body: 100mm x length: 300mm)
Speed regulation mode: The spindle speed can be changed by three-phase output inverter and adjusting the frequency of the inverter.
Cooling method: water cooling
Power interface: Optional H20-4 pin waterproof air plug. The air plugs labeled "1", "2", "3", "4", "1", "2", "3" are connected to the inverter (U, V, W), 4 are connected to the inverter The device is grounded.
Power: 4.5kw
Voltage: 220V 380V
Current: 12A/16A
Frequency: 0-400Hz
Speed: 0-24000rpm
Runout: less than 0.01mm
Diameter (mm): 100
4 fully sealed angular contact bearings
Chuck: ER20
Grease lubrication
Main purpose: used for wood, bamboo, ordinary PCB, PVC, PMMA, plastic, bamboo, two-color board (ABS) and other non-metallic carvings.

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.

●The water-cooled spindle must be used together with the water pump. Otherwise, the spindle will quickly break.
●The AC spindle motor must be used together with the inverter. The power of the inverter needs to be equal to or greater than the power of the spindle. Before use, please set the inverter parameters suitable for the spindle. Otherwise, the spindle and inverter will break immediately.
●When using the spindle, the noise is different from before, so please stop the spindle immediately. You need to replace the spindle bearing.
