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、數控泡沫雕刻機精細加工主軸的特點是低噪音、高轉速、高度，適合加工特別精細的工件，保麗龍雕刻機廠家，如泡沫、銘牌、胸牌禮品等。此類泡沫雕刻機主軸電機通常為高速變頻電機，功率較小，般在250w以下。缺點是切斷厚的材料的能力較差，不合切斷較厚的材料。

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、數控泡沫雕刻機大功率切斷主軸，主要用于切斷、大功率刻，特點是功率大，切割能力強，特別適合割宇、三立體字，當然也可以制作胸牌、銘牌、泡沫等。此類數控雕刻機大功率主軸根據電機的特性一般可分為無刷頻高速交流電機和有刷交流電機，其主要區別是：

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、無刷變頻電機轉速高，變速范圍為70060000轉/分鐘，而一般有刷交流電機泡沫轉速不超24000轉/分鐘：

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、無刷變頻電機旋轉精度高，磨損小，噪音低，作噪音大大低于有刷交流電機；

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

c、無刷變頻電機堵轉特性好，由于變頻器上有特的限流電路，短時間的堵轉不會燒毀電機，而有刷交流機在超負荷運轉或堵轉時會很快冒煙燒毀，且不可修復；

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、無刷變頻電機采用變頻控制技術調速，是級產品，壽命長，數控雕刻機廠家提供1年包換，以后還可以通過更換高速軸承對電機進行維護，而有刷交流電機由于使用電札壽命大約在300小時就得更換馬達或電機碳刷，所以碳刷交流電機通常---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，客戶在準備購買數控泡沫雕刻機前，要明確自己購買數控雕刻機的用途，這樣好根據用途來選擇數控雕刻機，確定數控雕刻機主軸大小。然后再根據具體加工所需，選擇相應的其他配置，合理的配置，才能的發揮泡沫雕刻機真正性能。

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.
