1. Before CNC Machining, please use a calibrator to check whether the tool swings within the allowable tolerance range. Before processing, the cutter head and locking nozzle should be blown clean with an air gun, or wiped with a cloth to install the knife. Accuracy and quality have a certain impact.

2. The program list of CNC processing files should be normalized, including model, name, program name, processing content, tool size, feed rate, especially the safe length of the tool holder, the reserved margin of each program and the indicator light. Knife. To be clearly stated.

3. The CNC machining program list should be consistent with the reference angle direction indicated by the mold, and then check the upper 3D diagram, especially the workpiece that has been drilled to transport water, and you must check whether the 3D diagram and the level on the workpiece are consistent.

4, before processing, you must understand the content of the CNC processing program, the program must have 2D or 3D mapping, and must be marked "X length, Y width, Z height" six-sided data, which should be marked as "Z" value, convenient for the operator to check whether the data is correct after processing. When there is tolerance, the tolerance data shall be indicated.

5, the rational use of CNC processing tools, should strictly distinguish between steel, copper knife processing, the remaining amount of light knife should be reasonable, so that the workpiece finish and tool life is possible. Better.

6. When clamping, please pay attention to whether the name and model of the CNC machining workpiece are the same as the program list, whether the material size matches, whether the clamping height is high enough, and the number of calipers used.

The CNC machining speed should be strictly controlled by the operator. F speed and S spindle speed should be adjusted reasonably. F When the speed is fast, the S spindle should be accelerated. The feed speed must be adjusted in different areas. After processing, check that there is no problem with the quality, and then you can get off the car and process it.
