is what we call CNC router machine. Its spindle motor can be classified as two kinds: precision processing spindle and high-power cutting spindle. The two kinds of spindles have their own advantages and disadvantages.
In the following, we will introduce the characteristics of the two spindles here for you.
1. CNC engraving machine fine processing spindle has the features of low noise, high speed, high precision. It is suitable for processing particularly fine workpieces, such as seals, nameplates, chest cards, etc. This kind of CNC machine spindle motor is usually a high-speed variable-frequency motor with low power, usually less than 250W. The disadvantage is that the ability to cut thick materials is poor, and it is not suitable for cutting thicker materials.
2. CNC Router cuts off the spindle with high power. It is mainly used for cutting and high power sculpture. It is characterized by high power and strong cutting ability. It is especially suitable for cutting and carving three-dimensional works. Of course, it can also be used to make breastplates, nameplates, seals, etc. Generally, it is used in carving with harder materials and larger workpieces. According to the characteristics of the motor, the high-power spindle of this kind of CNC Router can be generally divided into brushless frequency conversion high-speed AC motor and brush AC motor.
There are also differences between the two motors. Their main characteristics are as follows:
A. Brushless variable-frequency motors have high rotational speeds, ranging from 700 to 60,000 rpm, while brushless AC motors generally have a maximum rotational speed of less than 24,000 rpm.
B. Brushless frequency conversion motor has high rotating accuracy, low wear, and noise, and the noise is much lower than that of brushless AC motor.
C. Brushless variable-frequency motor has good blocking characteristics. Because of the special current limiting circuit on the converter, short-time blocking will not burn the motor, while the brush AC machine will burn up quickly when it is overloaded or blocked, and can not be repaired. This point should be paid special attention to by customers who use brush AC motor.
D. Brushless variable-frequency motor is a professional product with a long service life. Jinan Blue Elephant CNC Machinery Co., Ltd. provides a free replacement for one year. Later, the motor can be maintained by replacing the high-speed bearings. The motor or motor carbon brushes of brushed AC motors have to be replaced when their service life is about 300 hours. So carbon brush AC motors are usually not maintained.
So before buying a CNC router machine, you should be clear about the purpose of purchasing a CNC machine. We have a variety of CNC router for sale. You can communicate with customer service representative through our website so that you can choose the CNC Router according to its use and decide the size of the CNC Router spindle. Meanwhile, you can make an inquiry about CNC machine price. We are glad to help you buy the best CNC router!
