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

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

3. The CNC machining program list should be consistent with the reference angle direction indicated by the mold, and then check the upper 3D drawing, especially the workpiece that has been drilled with water. You must check whether the 3D drawing 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 textures, and must be marked with "X length, Y width, Z height" six-sided data, which should be flat marked as "Z" value, It is convenient for the operator to check whether the data is correct after processing. When there is a tolerance, the tolerance data should be indicated.

5. The reasonable use of CNC machining tools should strictly distinguish the processing of steel and copper light knives. The remaining amount of light knives should be reasonable to make the smoothness of the workpiece and the service life of the tools possible. better.

6. When clamping, please pay attention to whether the name and model of the CNC processed 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.

7, CNC processing speed should be strictly controlled by the operator. F speed and S spindle speed should be adjusted reasonably. When the F speed is fast, the S spindle should be accelerated. The paper feed speed must be adjusted in different areas. After processing, check the quality without any problems, then you can get off the car and perform perfect processing.
