PDF Manual

Low cost 800 kW water-cooled CNC spindle motor, 24000 rpm speed, 0.32 Nm torque, 400Hz frequency, 3 phase 220V AC operating voltage, ER11 (φ3.175 mm - φ7 mm) collet, stable performance and high precision bearing, good for CNC machines.

Feature

Spindle motor with superior durability ER11 collet ensures smooth running.
Fast response, strong overload capacity, low noise, and high mechanical precision.
High-quality 3 pcs bearings (7005Cx2 + 7002Cx1), runout off less than 0.01mm, tapered bore less than 0.005mm.
P4 grade ceramic ball bearings are used as spindle bearings, which improves the service life under high-speed revolution.
Lubricated with grease, which is resistant to 200 degrees high temperature.
Tight sealing and two-layer dustproof design.

Applications

This series of air-cooled electric spindle motors is designed primarily for use with variable frequency drives or engraving machines, as well as CNC routers. It is ideal for high-speed profiling, drilling, cutting, engraving, and groove milling across a variety of materials, including wood, metal, plastics, foam, and rubber.

Note: Ensure that the spindle motor and VFD are compatible. The VFD’s specifications and parameter settings must align with the spindle motor’s nominal parameters. Incorrect settings can lead to spindle motor damage or burnout.

800W Water Cooled CNC Spindle Motor Details

Tips: What should you do if the water-cooled CNC spindle motor is blocked?

Turn off the water pump, connect the air pipe of the air compressor to the water outlet of the main shaft, clean up the residue inside the main shaft with high-pressure air, blow for a while, connect the water pump for water circulation, and then repeat the previous steps, several times in a row, usually it can be solved
Use an air gun to blow through, increase the power of the water pump, and thicken the water pipe
The water quality of the water cycle is best to use barreled purified water, which can ensure that there are no impurities or scales. If you use tap water, you must pay attention to frequent replacement
Always pay attention to the water temperature of the water cycle. Too high water temperature will not have the effect of circulating cooling, which will affect the performance of the spindle motor

Safety Tips for Using ATO CNC Spindle Motors

1. The electric spindle motor and VFD shall be suitable with each other. The specifications and parameter settings of the VFD shall match the nominal parameters of the spindle motor, and it will burn the spindle motor if the settings are not correct.

2. Before using water-cooled spindle motor, it shall ensure that cooling cycle system works normally and the running under no cooling conditions is prohibited. The volume of cooling water is calculated as per 1 liter/minute, the minimum flow of cooling water is not less than 5 liter/minute, cooling water pipe and the nozzle shall be connected reliably and there is no leakage.

3. The cooling liquid shall be clean and free of grease and the temperature shall be within 5-30℃. The cooling medium shall carry out force cooling when the ambient temperature is higher than 30℃. The precision lathe requires the cooling liquid with a constant temperature of 20 +/-2℃.

4. During storage and transport of the spindle motor, the status of high-speed grease inside the bearing will change. The user shall run it at a low speed first by starting from the lowest speed of the spindle motor for 30 minutes and then 20 minutes for every 3000 rounds. Otherwise there will have abnormal sound, noise, heat and other phenomena, which will affect the bearing life if the spindle motor is started directly at a high speed. During long term storage, the spindle motor shall run (at low speed) for 15-30 minutes once a week at least.

5. Collet, nut and inner taper hole shall be washed clean when installing blades on the spindle motor in order to avoid any impact on the precision. The blade handle shall be inserted into the collet more than 15mm.

6. For daily machining, the spindle motor shall be warmed up, run for 15-20 minutes when the machining speed is reached and then performs precise machining. It is better to stop the spindle motor for two hours every day in order to recover its mechanical fatigue and prolong its life time.

7. No knocking the end cover of the spindle motor. No hammering the collet and blade head when removing blades. No shocking or colliding during transport, storage and using, especially the end of the spindle motor.

8. The spindle motor shall run in designated direction.

9. The spindle motor shall be installed and fixed according to the relevant drawings and instructions.

10. The temperature shall be within 22-25℃ if water cooling machine is used.

11. The spindle motor adopts vapor lock and the gas source shall not be used until it has passed oil-water separator and dry filter. The air pressure is 0.2-0.25Mpa and the filtering precision is 5μm, otherwise there will cause damages to the bearing.

ATO Responded

The type of motor here is a water-cooled spindle motor. Some water-cooled spindle motors can be equipped with air seals, but a dry, filtered, and clean air source must be used to extend the lifespan of the motor.

Good CNC spindle

My spindle arrived on time with very good protective packaging. It works well. This water-cooled spindle motor works in our CNC machine perfectly and quietly.
