  • Main Application: Engrave for wood,bamboo,normal PCB,PVC,PMMA,plastic,bamboo,duotone board(ABS)and etc nonmetal,also can engrave on gold,silver,copper,aluminium,Pb etc soft metal surface working.


Preparations before use:

  • Spindle working environment temperature is usually -10  ~ 40 .

  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.

Use correctly:
  • Spindle in the preservation and transportation, high-speed grease inside the bearing state will change, customers should be running at low speed for 30 minutes. 3000 rpm and then follow the poor increase, run 20 minutes each. Spindle and the inverter should be working together. The inverter's specifications and parameter settings need match spindles parameter.

  • Connect the inverter spindle, three-phase inverter power cord should be soldered in the plug 1 (U), 2 (V), 3 (W) feet, 4 feet for the ground. After the power is turned on, to observe whether the spindle rotation axis indicates the direction consistent. If inconsistency should be immediately shut down, replace the inverter and spindle connected two wires of three-phase power supply.

  • It should ensure that before use of water-cooled spindle, the cooling system is working properly. Every day before using the spindle must be running at low speed for 15-20 minutes. Clamping the cutters to spindle, collet nuts ,collets,cutters must be clean enough. Shank inserted into the collet must be greater than 15mm.

Care and maintenance:

  • Water cooled spindle MUST be used with water pump. Otherwise the spindle will soon broken.

  • AC spindle motor MUST use with inverter. The power of inverter need equal or bigger than the spindle power. Before using,please set up the inverter parameters suitable for spindle. Otherwise the spindle and inverter will broken at once.

  • When you use the spindle,the noise is not same as always,please STOP the spindle at once. You may need to replace the spindle bearings.

Water-colled spindle and air-cooled spindle differences:

  • 1. Cooling in different ways: water-cooled spindle motor is the use of the water cycle to cool the heat generated after the high-speed rotating spindle, spindle motor with fan-cooled approach to cooling.

  • 2. Noise: Water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very loud.

  • 3. Life aspects: Water-cooled spindle motor pay attention to maintenance, frequently changes the water or the use of industrial water coolers, air-cooled spindle fan mainly by the wind blowing the heat transferred to the heat sink, so as to achieve the cooling effect.

  • 4.If you need use for metal ,hard wood,granite,stone,you can choose metal spindle.Metal spindle much better than wood spindle.






Tech parameters:

  • Power: 2.2kw

  • 1) Input Voltage: 220V

  • 2) Output Voltage 220 VAC 

  • 3) Input Frequency: 50/60 Hz

  • 4) Output Frequency: 400 Hz

  • 5) Input Phase: 1  phase

  • 6) Output Phase: 3 phase  

  • 7) Contro Method: V/F control ; Open-loop flux vector control







Inverter input terminals

Connection point of AC input power supply, single-phase connects to R,T


Ground terminals

Ground terminals


Brake resistor terminals

Connect to brake resistor


Inverter output terminals

Connect to three-phase motor



1. Open-loop flux vector control---Vector inverter have a bigger torque in low frequency too. So the vector inverter have a good performe in 50~400Hz.

2. Closed loop control can be achieved. Vector inverters can easily implement closed-loop control, while V/F inverters are relatively complex.

3. Usually Vector inverter price higer 10% than normal V/F control, now we offer a very cheap price for vector inverter.

4. The volume of the spindle is small,so it save space of the controller box.

1.Compared with the aluminium profile fixture,the accuracy is much higher , and it is hard to deform.

2.Inner wall is very smooth,  outer walls is sandblasted, relatively fine uniform,  but not very smooth.

3.Cast aluminium fixture is much heavier than aluminium profile fixture.


Product Description:

Cast aluminium fixture is high quality aluminium which is casting with a special manufacturing process ,compared with ordinary aluminium ,This product has toughness, strong shock resistance, high hardness and strong antioxidant activity.

Commetns fondprim.ru :
The seller 6 days did not send the order, then sent from china, although the shipment was chosen from russia, because of this, from the moment of order to delivery to me, it took 2 weeks, could be faster. But, apparently as compensation, the seller put a conical cutter and a soft toy as a gift. The spindle itself is excellent, it already works on the machine, after 5 hour run-in everything is quiet., after the collector's chair is an excellent thing. The frequency has already been configured for the spindle. In a box with a spindle are two additional collets. Packed all on conscience. In general, the seller is handsome, you can take a small hitch with sending, and so everything is ok.

HI David, I received the package, everything is fine!
