5.5KW --380V-- HQD Water Cooling Spindle
HQD CNC Spindle Motor 5.5kw 380V ER25 Chuck lathe spindle High Torque CNC Milling Machine Metal Milling Mold Water-Cooled
Model: GDK125-18-24Z / 5.5kw
Size: 125x415mm (body diameter: 125mm x length: 415mm)
Speed regulation mode: The three-phase output inverter can change the spindle speed by changing the frequency of the inverter.
Cooling method: water cooling
Power interface: optional 4-pin waterproof air plug. The air plugs marked "1", "2", "3", "4", "1", "2", "3" have been connected to the inverter (U, V, W), and 4 has been connected to The inverter equipment is grounded.
Power: 5.5kw
Voltage: 380V
Current: 11A
Frequency: 300-400Hz
Speed: 18000-24000rpm
Cone hole: 2UM
Diameter (mm): 125
4 fully sealed angular contact ceramic bearings
Chuck: ER25
Grease lubrication
Main use: Carving wood, bamboo, ordinary PCB, PVC, PMMA, plastic, two-color board (ABS) and other non-metals, and can also be carved on soft metal surfaces such as gold, silver, copper, aluminum, Pb, etc.
●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 contact ceramic bearings can extend the service 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. Ceramic ball bearings have low friction, low noise and long service life.
●When the HQD CNC spindle motor 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 lathe 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 HQD CNC spindle motor 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 lathe spindle.
●Before using the spindle every day, it must run at low speed for 15-20 minutes. Clamp the cutter on the HQD CNC spindle motor, the chuck nut, chuck, and cutter must be clean enough. The shank inserted into the chuck must be larger than 15mm.
●The water-cooled lathe 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 HQD CNC spindle motor. Otherwise, the spindle and inverter will break immediately.
●When using the HQD CNC spindle motor, the noise is different from before, so please stop the spindle immediately. You need to replace the spindle bearing.
