One of the most important components of an engraving machine is the spindle. The spindle is divided into air-cooled spindle and water-cooled spindle. The air-cooled spindle

uses a fan to dissipate heat. The water-cooled spindle uses water circulation to cool the spindle. The quality of the spindle directly affects the processing speed and accuracy of

the engraving machine. Many users often ask which style of spindle motor to choose when choosing an engraving machine? What aspects should be considered when purchasing

an engraving machine spindle? When customers purchase engraving machine spindle equipment, they must pay attention to selecting a suitable engraving machine spindle based

on the machine tool performance and processing technology.

If you choose the spindle based on the material, then you must first choose the spindle based on the material of the carving. Generally speaking, when carving hard metal materials,

 you generally need to choose a spindle with relatively large torque and power, because when carving hard materials, if the power is too small, it will easily cause the carving to fail. 

During the process, vibration will occur and the knife will break, so the speed requirement does not need to be too high, and high-precision and low-speed engraving can be ensured. 

When engraving some materials that are not very hard, such as acrylic, non-metallic materials, etc., because the material is not very hard, there are often certain speed requirements. 

Generally speaking, you will choose a spindle with a higher speed, depending on your actual needs. The speed can be controlled via a frequency converter.

If you choose a spindle based on the machine model, the following are the key points:

1. Advertising engraving machine: The object of engraving is relatively soft material, so the spindle power of the advertising engraving machine should be within 1.5kw-3.0kw. This choice

 can not only achieve the purpose of engraving but also save costs.

2. Woodworking engraving machine: The spindle motor of the woodworking engraving machine can be selected according to the hardness of the wood being processed. Its power is 

generally around 2.2kw-4.5kw. This combination is also the most reasonable.

3. Stone engraving machine: The main shaft power of the stone engraving machine used by the manufacturer is relatively high, generally around 4.5kw-7.5kw, and the most commonly 

used one is the 5.5kw spindle motor.

4. Tombstone engraving machine: The spindle power of the tombstone engraving machine should also be selected according to the hardness of the stone being processed. Generally, 

the power of 3.0kw-4.5kw can meet customer needs.

5. Jade engraving machine: Because of its small bed, the power of the spindle motor of the jade engraving machine is generally 2.2kw-3.0kw.

If the power of the spindle motor is too large, it will not only waste electric energy but also increase the purchase cost. If the power of the spindle motor is too small, it will not meet the

 engraving power requirements, so it is very important to choose the appropriate power of the spindle motor!

The above are the methods for selecting the electromechanical spindle for engraving from different aspects. I hope it will be helpful to everyone!
