Brief: this item for sale here is 5.5kw high speed stone working electrospindle. The spindle shape seems a bullet head. It is the best spindle motor specially built for for stone, aluminum and copper machining purpose. If you are working on those materials, a stone cnc router with stone working electrospindle is the best solution.

What difference does this water cooled electrospindle have when compared with ordinary woodworking router spindle motors

To answer this question, let's take a look at the difference between stone processing and wood machining first.

From the raw material hardness, stone is much harder than wood.

Stone and metal need to be machining with water shower; while wood no need. The water recycle system spray water on router cutters and table for two purpose mainly: cooling the cutters and reducing the dust. 

Obviously, a woodworking spindle is very difficult for stone or light metal processing tasks. That’s why a special spindle motor is needed for this purpose. Here is the answer for previous question.  

1) This cnc electrospindle is longer in size than wood using ones. To machining stone, aluminum or brass, it should have bigger torque. Torque is determined by the electric current of spindle; under the same voltage, the bigger the output current is, the bigger the output torque is. How to increase the electric current? All the spindle manufacturers make this way: increasing the length or diameter of the stator.

2) 
This item adopts 4 pieces P4 precision grade ceramic ball bearing to suitable for hard materials machining. Because compared with metal balls, ceramic balls are more wearable and less prone to heat. The woodworking electric spindle generally have 3 pieces metal ball bearings. In most case, spindle bearing determines the service life of spindle.

3) 
This electrospindle motor is prior to woodworking ones on performance of seal and water proof. In addition, the bullet head design in front has the excellent water throwing characters.
