How to choose the power of motorized spindle of NC engraving machine? Is the higher the power, the better? Of course not.

数控雕刻机的主轴电机的功率要根据所雕刻的对象进行选择，下面我们介绍一下：

The power of spindle motor of NC engraving machine shall be selected according to the engraving object. Let's introduce it below:

根据客户加工的材料、质量效果来进行选择主轴的功率大小，浮雕、镂空、切割、刻字等加工效果选择的主功率是不一样的，有的加工材料本身的硬度不同也会选择不同功率！大部分都会选择能够满足需求后偏大一点比较好。电机的实际消耗功率与负载有关，同样的负载下，大小功率的主轴实际耗电相差不大。但是由于转动体重量、轴承尺寸等，一般而满足需求后偏大一点比较好。对于雕刻机主轴来说，同样的负载下，大小功率的的主轴实际耗电相差不大。

Choose the power of the spindle according to the materials and quality effects processed by customers. The main power selected for the processing effects such as relief, hollowing out, cutting and lettering is different. Some processing materials will choose different power due to their different hardness! Most of them will choose to be a little bigger after meeting the demand. The actual power consumption of the motor is related to the load. Under the same load, the actual power consumption of the spindle with large and small power is almost the same. However, due to the weight of the rotating body and the size of the bearing, it is generally better to be a little larger after meeting the demand. For the engraving machine spindle, under the same load, the actual power consumption of the spindle with large and small power is almost the same.

普通的选择如下：

Common choices are as follows:

广告雕刻机：雕刻对象为比较软的材质所以广告雕刻机的主轴功率在1.5kw—3.0kw以内就可以，这样选择的话既可以达到雕刻目的还能节省成本。

Advertising engraving machine: the engraving object is a relatively soft material, so the main shaft power of the advertising engraving machine can be within 1.5kw-3.0kw. In this way, the engraving purpose can be achieved and the cost can be saved.

木工雕刻机：木工雕刻机的主轴电机可根据所加工木料的硬度进行选择其功率：一般在2.2kw—4.5kw左右，这也是普通选择。

Woodworking engraving machine: the spindle motor of woodworking engraving machine can be selected according to the hardness of the processed wood. Its power is generally about 2.2kw-4.5kw, which is also a common choice.

石材雕刻机：厂家用石材雕刻机的主轴功率相对要高一些，一般在4.5kw—7.5kw左右，更常用的还是5.5kw主轴电机

Stone carving machine: the spindle power of the stone carving machine used by the manufacturer is relatively higher, generally about 4.5kw-7.5kw, and the most commonly used is the 5.5kW spindle motor

墓碑雕刻机：墓碑雕刻机的主轴功率也要根据所加工的石料硬度进行选择，一般功率在3.0kw—4.5kw即能满足客户需求

Tombstone engraving machine: the spindle power of the tombstone engraving machine should also be selected according to the hardness of the processed stone. Generally, the power is 3.0kw-4.5kw, which can meet the needs of customers

玉石雕刻机：玉石雕刻机由于其床身较小主轴电机的功率一般在2.2kw-3.0kw即可。

Jade carving machine: due to its small bed, the power of main shaft motor of jade carving machine is generally 2.2kw-3.0kw.

主轴电机功率太大不仅浪费电能还会增加客户的购机成本，功率太小的话又不能其雕刻功率需求，所以选择适合自己的主轴电机的功率对客户来说是相当重要的!

If the power of spindle motor is too large, it will not only waste electric energy, but also increase the purchase cost of customers. If the power is too small, it can not meet the engraving power demand. Therefore, it is very important for customers to choose the power of spindle motor suitable for themselves!
