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 cutter head and locking nozzle, or wipe with a cloth to install the cutter. 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 toolholder, 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 diagram, especially the workpiece that has been drilled and transported. It is necessary to 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 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 between 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 tool 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. The 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.

After the CNC machining machine enters the machining operation according to the program, the operator is not allowed to touch the moving workpiece, cutter and transmission part, and it is forbidden to transfer or take away tools and other items through the rotating part of the machine tool. The machine must be stopped when adjusting the machine tool, clamping workpieces and tools, and wiping the machine tool. It is not allowed to place tools or other objects on electrical appliances, operation boxes and protective covers.

It is not allowed to directly remove iron filings by hand. Special tools should be used for cleaning. If abnormal conditions and alarm signals are found, stop immediately and ask relevant personnel to check. Don’t leave your work while the machine is running. If you want to leave for some reason, put the workbench in the middle position, return to the cutter bar, stop the machine and cut off the main machine.
