1. Before carrying out CNC machining, please use a calibrator to check if the tool is shaking within the allowable tolerance range. Before processing, the blade and locking nozzle shall be blown clean with a Heat gun, or the knife shall be installed by wiping with a cloth. Accuracy and quality pose certain risks.
2. The program list of CNC machining documents should be normalized, including the model specifications, names, program flow names, machining content, tool specifications, cutting speed, especially the safety length of the tool holder, as well as the embedded allowance and display lights for each program flow. Knife. It should be clearly stated.
3. The CNC machining program list should be consistent with the reference angle and orientation marked on the mold. Then, check the upper 3D diagram, especially for workpieces that have already been drilled and connected to water. It is important to check whether the 3D diagram and the level on the workpiece are consistent.
4. Before carrying out machining, it is necessary to master the content of the CNC machining program flow. The program flow must have 2D or 3D3d maps, and must be labeled with "X length, Y width, Z height" hexahedral data information, which should be flat marked with the "Z" value to facilitate operators to check whether the program is appropriate after machining. When there is a tolerance, tolerance data information should be indicated.
5. Reasonable use of CNC special tools for machining should strictly distinguish between stainless steel plates, small hardware parts for processing copper male light knives, and the remaining amount of laser knives for processing hardware products should be effective to make the smoothness of the workpiece and the lifespan of the tools very likely. Stronger.
6. When clamping, be sure to pay attention to whether the name, model and specification of CNC machining workpiece are the same as those in the program list, whether the specifications of raw materials are matched, whether the clamping height width ratio is high enough, and the total number of Vernier scale applied.
7. The CNC processing speed should be strictly controlled by the operator. The F speed and S spindle bearing speed should be effectively adjusted. When the F speed is fast, the S spindle bearing should be accelerated. The paper feeding speed must be adjusted in different areas. After processing, there are no difficulties in checking the quality, and then you can get off the car and start processing.
