Jade carving machine is a commonly used jade carving equipment at present. It has the characteristics of simple operation, easy learning and fast carving speed. It has always been regarded as the favorite of jade carving industry. The following jade carving machine manufacturers will briefly introduce the actual operation of jade carving machine.

玉石雕刻机的实际操作大致可以分为三步：

The actual operation of jade carving machine can be roughly divided into three steps:

一：切轮廓，切轮廓一般使用的是3毫米的金刚砂直棒，做轮廓切割刀路，这一步非常简单。

1： Cut the contour. Generally, a 3mm emery straight rod is used to cut the contour. This step is very simple.

二：开粗，开粗有两种方法，各有利弊，下面玉石雕刻机厂家分别说一下这两种方法。

2： There are two methods for rough opening, each with its own advantages and disadvantages. The following jade carving machine manufacturers will talk about these two methods respectively.

一是分层雕刻，分层开粗的优点是速度比较快，缺点是后面走精刀容易过早磨损刀头，出现分层现象。使用的是3毫米金刚砂球头刀，做分层雕刻刀路，一般根据料子的硬度决定每层切削的厚度，一般是0.2~0.5MM。上机雕刻，雕刻完成。

One is layered engraving. The advantage of layered rough opening is that the speed is relatively fast, but the disadvantage is that it is easy to wear the cutter head prematurely and cause delamination. The 3mm emery ball head cutter is used to make the layered carving path. Generally, the cutting thickness of each layer is determined according to the hardness of the material, which is generally 0.2 ~ 0.5mm. Machine engraving, engraving completed.

二是开粗方法是粗刀曲面精加工，这种方法的优点是后期精刀不容易断刀头，缺点是雕刻时间比分层雕刻方式长。使用的是30度1毫米的金刚砂锥度球头刀，如果是软玉可以用直径更小的锥度球头刀。做曲面精加工刀路，曲面边界补偿选自动向外，关闭进刀方式，尖角过滤方式选直线延迟。上机雕刻，雕刻完成。

Second, the rough cutting method is rough cutter surface finish machining. The advantage of this method is that it is not easy to break the cutter head in the later fine cutter, and the disadvantage is that the engraving time is longer than the layered engraving method. The use is a 30 degree 1mm emery taper ball head knife. If it is nephrite, a taper ball head knife with smaller diameter can be used. Do surface finishing tool path, select automatic outward for surface boundary compensation, turn off feed mode, and select linear delay for sharp angle filtering mode. Machine engraving, engraving completed.

第三步：精刀，末尾这一步使用的是30度锥度平底四棱刀，大家可以根据实际情况选择合适角度的刀具。出曲面精加工刀路，路径间距自己掌握，我一般为了后期抛光方便，所以使用的是0.023的间距。

The third step: fine cutter. In the last step, the 30 degree taper flat bottom four edge cutter is used. You can choose the cutter with appropriate angle according to the actual situation. The path spacing of the finish machining tool path of the curved surface shall be controlled by myself. I generally use the spacing of 0.023 for the convenience of later polishing.
