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.
The actual operation of jade carving machine can be roughly divided into three steps:
1： Cut the contour. Generally, a 3mm emery straight rod is used to cut the contour. This step is very simple.
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.
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.
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.
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.
