How to improve the quality of CNC machining parts

1, Before CNC machining, please use the calibrator to check whether the tool is swinging within the allowed tolerance range. Before processing, the cutter head and locking nozzle should be blown clean with a wind gun, or wiped 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 amount, especially the safe length of the tool holder, the reservation margin of each program and the indicator light. A knife. Be specific.
3, the list of CNC machining procedures should be consistent with the direction of the reference Angle indicated by the mold, and then check the upper 3D drawing, especially the workpiece that has been drilled and transported water, you must check whether the 3D drawing and the level on the workpiece are consistent.
4, before processing, it is necessary to understand the content of the CNC machining program, the program must have 2D or 3D maps, and must be marked with "X length, Y width, Z height" six sides of the data, which should be flat marked with "Z" value, convenient for the operator to check whether the data is correct after processing. Tolerance data should be indicated when tolerances are available.
5, the reasonable use of CNC machining tools, should strictly distinguish the processing of steel, copper knife, the remaining amount of the knife should be reasonable, in order to make the workpiece finish and tool life possible. Even better.
6. When clamping, please note 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.
7, CNC machining speed should be strictly controlled by the operator. F speed and S spindle speed should be reasonably adjusted. When the speed of F is fast, the S spindle should be accelerated. The feed speed must be adjusted in different areas. After processing, check that there are no problems with the quality, and then you can get off the car and carry out perfect processing.
