How to improve the quality of cnc machining parts


 1. Reasonable cnc machining of machining tools with copper and aluminum parts
The processing of steel and copper knives should be strictly differentiated. The remaining amount of the optical knives should be reasonable, so that the smoothness of the workpiece and the length of use of the knives will be better.

2. Before cnc processing, use the calibration meter to check (check and test) whether the tool is swinging within the allowable tolerance range. The cutter head and the lock nozzle should be blown clean with a wind gun before cleaning, or wiped with a cloth to install the knife. Too dirty is a certain influence on the accuracy and quality of the workpiece.
3. When clamping, pay attention to see if the name and model of the cnc machining workpiece and the program list are the same, whether the material size matches, whether the clamping height is high enough, and the number of calipers is used.

4. The CNC machining program list should be consistent with the reference angle indicated by the mold, and then check whether the upper 3D drawing is correct. Especially for the workpiece that has been transported with water, it is necessary to see the 3D drawing and the workpiece water conveyed. Is it consistent? If there is any unclear, please promptly feedback the programmer or find the fitter master to view the 2D drawings and see if the 2D and 3D reference angles are consistent. To change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

5. The program list of the CNC machining file should be normalized, including the model number, name, program name, machining content, tool size, feed amount, especially the tool clamp safety length, the reserved margin for each program, and the light knife. It should be clearly stated that the R surface and the plane should be connected smoothly. It should be indicated on the program list. The operation controller should increase the processing by 0.02-0.05MM during processing. If it is a few knives, stop it and see if it is connected. , touch the hand to see if it is up, if not, then lower it.

6, before processing, you must understand the contents of the CNC machining program, the program must have 2D or 3D map, and must be marked; X length, Y width, Z height; six sides of data. If there is a flat surface to be marked, the operator can easily detect (check and test) the data after processing, and the tolerance data should be indicated.

7. The machine tool processing speed operation controller should be strictly controlled. The F speed and the S spindle speed should be properly adjusted with each other. When the F speed is fast, the S spindle should be accelerated. The feed speed must be adjusted in different areas.

No matter the precision and precision of the cnc machining center, there may be problems with the quality of the machined workpiece. In this case, don't panic. Only find the real reason to make a solution.
