With the increasing utilization rate of CNC foam engraving machine, cognition and understanding are also increasing. In the eyes of many people, it may feel that CNC foam carving machine is very - full automation can engrave all kinds of relief crafts. In fact, if you really understand the working principle of the engraving machine, you will understand its real name. CNC foam engraving machine is mainly composed of machine tools, spindle, Longmen, control system, transmission system and so on, among which spindle motor is particularly important. CNC engraving machine spindle motor is also divided into precision machining spindle and high-power cutting spindle. According to the different processing conditions of customers, the difference of spindle motor is also very big. Today, Baolilong engraving machine introduces in detail the selection and differentiation of spindle motor.

1、数控泡沫雕刻机精细加工主轴的特点是低噪音、高转速、高度，适合加工特别精细的工件，保丽龙雕刻机厂家，如泡沫、铭牌、胸牌礼品等。此类泡沫雕刻机主轴电机通常为高速变频电机，功率较小，般在250w以下。缺点是切断厚的材料的能力较差，不合切断较厚的材料。

1. The precision machining spindle of CNC foam engraving machine is characterized by low noise, high speed and high height. It is suitable for machining specially fine workpieces, such as foam, nameplate, chest card gift, etc. This type of foam carving machine spindle motor is usually high speed variable frequency motor, less power, below 250W. The disadvantage is that the ability to cut thick materials is poor, not suitable for cutting thick materials.

2、数控泡沫雕刻机大功率切断主轴，主要用于切断、大功率刻，特点是功率大，切割能力强，特别适合割宇、三立体字，当然也可以制作胸牌、铭牌、泡沫等。此类数控雕刻机大功率主轴根据电机的特性一般可分为无刷频高速交流电机和有刷交流电机，其主要区别是：

2, CNC foam engraving machine high-power cutting spindle, mainly for cutting, high-power engraving, characterized by large power, cutting ability, especially suitable for cutting Yu, three three-dimensional characters, of course, can also make chest cards, nameplates, foam and so on. According to the characteristics of the motor, the high-power spindle of CNC engraving machine can be divided into brushless high-speed AC motor and brushless AC motor

a、无刷变频电机转速高，变速范围为70060000转/分钟，而一般有刷交流电机泡沫转速不超24000转/分钟：

A, brushless variable frequency motor speed is high, the speed range is 70060000 R / min, and generally brush AC motor foam speed is not more than 24000 rpm.

b、无刷变频电机旋转精度高，磨损小，噪音低，作噪音大大低于有刷交流电机；

b. The brushless variable frequency motor has the advantages of high rotation accuracy, low wear and low noise;

c、无刷变频电机堵转特性好，由于变频器上有特的限流电路，短时间的堵转不会烧毁电机，而有刷交流机在超负荷运转或堵转时会很快冒烟烧毁，且不可修复；

c. Due to the special current limiting circuit on the frequency converter, the motor will not be burnt out in a short time due to the special current limiting circuit on the frequency converter, while the brush AC machine will quickly smoke and burn out when it is overloaded or locked, and cannot be repaired;

d、无刷变频电机采用变频控制技术调速，是级产品，寿命长，数控雕刻机厂家提供1年包换，以后还可以通过更换高速轴承对电机进行维护，而有刷交流电机由于使用电札寿命大约在300小时就得更换马达或电机碳刷，所以碳刷交流电机通常---也不保修。

d. Brushless variable frequency motor adopts frequency conversion control technology for speed regulation. It is a class product with long service life. The CNC engraving machine manufacturer provides one year free replacement. In the future, the motor can be maintained by replacing the high-speed bearing. However, due to the service life of the brush AC motor is about 300 hours, the motor or motor carbon brush must be replaced, so the carbon brush AC motor is usually not guaranteed.

所以，客户在准备购买数控泡沫雕刻机前，要明确自己购买数控雕刻机的用途，这样好根据用途来选择数控雕刻机，确定数控雕刻机主轴大小。然后再根据具体加工所需，选择相应的其他配置，合理的配置，才能的发挥泡沫雕刻机真正性能。

Therefore, before preparing to buy CNC foam engraving machine, customers should make clear the purpose of purchasing CNC engraving machine, so that the CNC engraving machine can be selected according to the purpose, and the spindle size of CNC engraving machine can be determined. Then according to the specific processing needs, choose the corresponding other configuration, reasonable configuration, in order to play the real performance of the foam carving machine.
