HF PETG welding and cutting machine.The actual operation of a carving machine can be roughly divided into three steps

　　Cutting the contour, usually using a 3mm diamond straight rod to cut the contour, this step is very simple. Rough machining has two methods, each with its own advantages and disadvantages. Below, jade carving machine manufacturers will discuss these two methods separately.

　　1. The carving machine is a layered carving. The advantage of layered rough machining is its fast speed, but the disadvantage is that the precision cutting tool will wear the tool head too early, causing layering. 3mm diamond ball head knife is used for layered carving. The thickness of each layer is generally determined based on the hardness of the material, which is usually 0.2-0.5mm. Engraving on the machine, completed.

　　2. The rough machining method of a carving machine is to use a rough knife for surface finishing. The advantage of this method is that the blade is thin and not easily broken in the later stage. The disadvantage is that the carving time is longer than the layered carving method. Use a 30 degree 1mm corundum taper ball cutter. If it is soft jade, a conical bead knife with a smaller diameter can be used. Perform surface precision machining tool path, select automatic outward surface boundary compensation, turn off feed mode, and select linear delay for sharp angle filtering. Engraving on the machine, completed.

　　3. Engraving machine precision knife, this step uses a flat bottomed four blade knife with a 30 degree taper, and the appropriate angle of the knife can be selected according to the actual situation. For surface precision machining tool paths, the path spacing is controlled by yourself. I usually use a spacing of 0.023 for later polishing.
