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，我們又稱機器的“進料高度”。是從雕刻機的臺面表面到橫梁底部的上下垂直距離。更嚴格地講，進料高度指的是雕刻機既能通過，又能雕刻的材料厚度。標準機器的進料高度，指的是龍門、橫梁底部到雕刻機臺面的距離。進料高度很重要，我們需要確定厚的石材，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.

一般來說，雙頭雕刻機，兩個頭同時開，每個頭的大雕刻尺寸是機器總雕刻尺寸的一半。如果只開一個機頭，機器的大雕刻尺寸，小于機器的總雕刻尺寸，需要減去單個機頭的寬度和防塵罩收縮之后的寬度。了解機器的外形尺寸，主要是考慮工作場地的面積大小、門的寬度、機器配套設施的位置。機器的工作電源，是三相電還是單相電，是380伏還是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.

對進料高度，給選購石材雕刻機的客戶，提幾個建議：

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

1、如果廠家沒有問你，那么你一定要問清楚，該機器的進料高度是多少？

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

2、向廠家認真確定，這臺機器大能雕刻多厚的材料，也就是機器的Z軸雕刻行程是多少。

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、進料高度不是越大越好，而是既足夠使用，又不要太大。有的客戶貪圖便宜，以為進料高度越大，就越不用擔心以后不能雕刻厚材料。機器進料高度過大，會導致以下弊端：降低了機器的剛性、振動變大、負載變大導致電機扭矩不足、裝配精度下降、容易斷刀、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、常見的石材雕刻機進料高度有30公分、40公分、50公分。一般來講進料高度大于50公分，要采取以下措施：機床材料加厚、加筋以增加剛性；熱處理應力減少振動和變形；驅動電機選用大型號以增 大扭力或加裝氣缸；裝配精度要求更高等。

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.
