How to improve the quality of the workpiece during four-axis cnc machining?
1. Before performing four-axis cnc machining, it is recommended to use a calibration instrument to check whether the tool is operating 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 cutter, otherwise the accuracy and quality will be affected.
2. When machining workpieces with four-axis cnc, the overall program list should be clear, including model, name, program name, processing content, tool size, feed, especially the safe length of the tool holder, the reserved margin for each program, and indicator light. To be clearly stated.
3. The list of CNC machining workpieces 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 to transport water, 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 machining process, the process must be accompanied by 2D or 3D maps, and the six-sided data of "X length, Y width, Z height" must be marked, and the "Z" value must be marked flat. , which is convenient for technicians to check whether the data is correct after processing. If there is tolerance, the tolerance data should be indicated.
5. When using four-axis cnc machining tools reasonably, it is necessary to carefully distinguish between the processing of steel and copper materials, and whether the remaining amount of the smooth knife is reasonable, so as to ensure the smoothness of the workpiece and the service life of the tool for a longer time.
6. In the clamping process, please pay attention to whether the name and model of the CNC machined 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 speed of four-axis cnc processing needs to be strictly controlled by technical operators, and the F speed and S spindle speed should be adjusted reasonably. When the F speed is high, the S spindle should be accelerated. The feed speed must be adjusted in different areas. After machining, check the quality without any problems, then the machining process of the four-axis CNC can be completed.
