1.Spindle power: One type is a low-power spindle, which has a small scope of application and is only suitable for processing materials such as color plates, small signs, and three-dimensional processes. The other is a high-power spindle, which is divided into two types. One is a large stone CNC machine tool, the working size is generally more than 1 meter, but the processing accuracy is generally very poor; the other is a medium-sized stone CNC machine tool, generally used for fine processing.
2.Spindle motor: The spindle needs to work when there is a high voltage. If the motor is not very good, the service life and efficiency will be affected.
3.Adjust the spindle speed range: Generally, the adjustable speed range is from several thousand to 30,000 revolutions per minute. If the speed is not adjustable or the adjustable speed is small, it indicates that its application range is very limited.
4.Car body manufacturing process: High-power machine tool car bodies must be precise and stable when working. Therefore, in order to ensure its processing accuracy and stability, machine tool body casting should be used.
5.Ball screws and guide rails: Affect the accuracy and usage time of the machine.
