Explanation and suggestion of feeding height of engraving machine. Feeding height is an important data of engraving machine. What is the feed height? How much feed height do we choose? Next, poly dragon engraving machine manufacturers will give you detailed explanations and suggestions.

材料的大厚度，我们又称机器的“进料高度”。是从雕刻机的台面表面到横梁底部的上下垂直距离。更严格地讲，进料高度指的是雕刻机既能通过，又能雕刻的材料厚度。标准机器的进料高度，指的是龙门、横梁底部到雕刻机台面的距离。进料高度很重要，我们需要确定厚的石材，它的“厚度”是多少。

The large thickness of the material is also called the "feeding height" of the machine. It is the vertical distance from the table surface of the engraving machine to the bottom of the beam. More strictly speaking, the feed height refers to the material thickness that the engraving machine can both pass through and carve. The feeding height of the standard machine refers to the distance from the bottom of the gantry and beam to the table top of the engraving machine. The feeding height is very important. We need to determine the "thickness" of thick stone.

一般来说，双头雕刻机，两个头同时开，每个头的大雕刻尺寸是机器总雕刻尺寸的一半。如果只开一个机头，机器的大雕刻尺寸，小于机器的总雕刻尺寸，需要减去单个机头的宽度和防尘罩收缩之后的宽度。了解机器的外形尺寸，主要是考虑工作场地的面积大小、门的宽度、机器配套设施的位置。机器的工作电源，是三相电还是单相电，是380伏还是220伏。

Generally speaking, two heads of a double headed engraving machine are opened at the same time, and the large engraving size of each head is half of the total engraving size of the machine. If only one head is opened, the large engraving size of the machine is less than the total engraving size of the machine. The width of a single head and the width after the dust cover is shrunk need to be subtracted. Understand the overall dimensions of the machine, mainly considering the area of the work site, the width of the door and the location of the supporting facilities of the machine. The working power supply of the machine is three-phase or single-phase, 380 V or 220 v.

对进料高度，给选购石材雕刻机的客户，提几个建议：

For the feeding height, give some suggestions to customers who choose stone carving machine:

1、如果厂家没有问你，那么你一定要问清楚，该机器的进料高度是多少？

1. If the manufacturer does not ask you, you must ask clearly, what is the feeding height of the machine?

2、向厂家认真确定，这台机器大能雕刻多厚的材料，也就是机器的Z轴雕刻行程是多少。

2. Carefully confirm with the manufacturer how thick the material can be carved by this machine, that is, how much the z-axis carving stroke of the machine is.

3、进料高度不是越大越好，而是既足够使用，又不要太大。有的客户贪图便宜，以为进料高度越大，就越不用担心以后不能雕刻厚材料。机器进料高度过大，会导致以下弊端：降低了机器的刚性、振动变大、负载变大导致电机扭矩不足、装配精度下降、容易断刀、雕刻不平。

3. The feed height is not the bigger the better, but enough for use and not too large. Some customers are greedy for cheap and think that the higher the feed height, the less they need to worry about not carving thick materials in the future. The excessive feeding height of the machine will lead to the following disadvantages: reducing the rigidity of the machine, increasing vibration and load, resulting in insufficient motor torque, reduced assembly accuracy, easy knife breaking and uneven carving.

4、常见的石材雕刻机进料高度有30公分、40公分、50公分。一般来讲进料高度大于50公分，要采取以下措施：机床材料加厚、加筋以增加刚性；热处理应力减少振动和变形；驱动电机选用大型号以增 大扭力或加装气缸；装配精度要求更高等。

4. The feeding height of common stone carving machines is 30 cm, 40 cm and 50 cm. Generally speaking, if the feeding height is greater than 50 cm, the following measures shall be taken: thickening and reinforcement of machine tool materials to increase rigidity; Heat treatment eliminates stress and reduces vibration and deformation; Large size drive motor is selected to increase torque or add cylinder; Higher assembly accuracy is required.
