Grease lubrication
Main uses: engraving wood, bamboo, ordinary PCB, PVC, PMMA, plastic, two-color board (ABS) and other non-metals. It can also engrave gold, silver, copper, aluminum, lead and other soft metal surfaces, ETC.

The working environment temperature of the spindle is usually -10℃~40℃.
Before installing the first electric spindle, turn the spindle head by hand. It should feel flexible and free of sticking.

P4 fully sealed angular contact ceramic bearings 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.
Accuracy 0.01mm, coaxial cable less than 0.0025mm
1. Our spindle 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 in the high-speed grease will change. Customers should run it at low speed for 30 minutes. Then slowly increase the speed to 3000 rpm, running for 20 minutes each time. The lathe spindle and frequency converter should work together. The specifications and parameter settings of the frequency converter match the spindle parameters.
When connecting the inverter spindle, the three-phase inverter power cord should be welded to plug 1 (U), 2 (V), 3 (W) pins and ground pin 4. After turning on the power, observe whether there are any abnormalities. The rotation axis of the HQD CNC spindle motor always displays the direction. If they are inconsistent, shut down the machine immediately and replace the two three-phase power supply wires connecting the inverter and the lathe spindle.
Before using the spindle every day, it must be run at low speed for 15-20 minutes. Clamp the tool on the HQD CNC spindle motor. The chuck nut, chuck, and tool must be clean enough. The shank inserted into the chuck must be larger than 15mm.

The water-cooled lathe spindle must be used with a water pump. Otherwise, the spindle will break quickly.
AC spindle motor must be used in conjunction with a frequency converter. The power of the frequency converter 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 frequency converter will be damaged immediately.
When using the HQD CNC spindle motor, the noise is different from before, please stop the spindle immediately. You need to replace the spindle bearings.

1. Different cooling methods: the water-cooled spindle motor uses water circulation to cool the heat generated by the high-speed rotation of the spindle, while the HQD CNC spindle motor uses fan cooling for cooling.

2. Noise: The lathe spindle motor has basically no noise, but the air-cooled spindle motor is very noisy.

3. Lifespan: Water-cooled spindle motors should be maintained and maintained frequently, and the water should be changed frequently or an industrial water cooler should be used. The air-cooled spindle fan mainly blows heat to the radiator through wind to achieve a cooling effect.

4. If you need to use metal, hardwood, granite, or stone, you can choose a metal mandrel. Metal mandrels are much better than wooden mandrels.

The frequency conversion power supply of the HQD CNC spindle motor is connected to the rated voltage, and the frequency should be consistent with the technical parameters of the electric spindle. Adjusting the lathe spindle speed can change the frequency, and the voltage also changes proportionally.
Do not use the spindle and use compressed air to blow out the stagnant coolant in the pipeline. To prevent rust, plug water holes. The spindle should be oiled. Add wave protection and place in a dry place.
Spindle bearings should be replaced by professional technicians. Special tools should be used to thoroughly clean the bearings without removing the stator coils.
