Although the technology of CNC milling machine has improved a lot now, we still need to pay attention to the changes. Because the processing of CNC milling machine is relatively rigorous, so many people still have a great advantage in this industry. The advantage is only Yes, but when many manufacturers choose processing, they still choose good quality, and their reputation and experience are still very high. Because of these advantages, CNC milling machines have much higher workmanship guarantees. The price of CNC milling machine is basically available in the eyes of manufacturers.


Analysis of processing size requirements

    The processing requirements of the workpiece are the main basis for completing the processing. Generally, there are clear annotations on the drawings of the workpiece. The dimensions of the workpiece drawing confirm the shape, structure, and location requirements of the part, which is the main basis for correctly understanding the processing requirements of the workpiece.

In the numerical control processing of small numerical control milling machine, the first-line processing personnel should analyze the following points:


    First, analyze whether the geometric elements of the machining contour in the workpiece pattern are sufficient; second, analyze whether the design basis and process positioning datum can be unified, so as to confirm the clamping plan; third, analyze whether the drawing dimensioning method can conform to the characteristics of CNC programming. For the CNC machining of small CNC milling machines, the dimensions are marked from the same datum, which is convenient for insisting on the differences of design, process, inspection datum and programming origin setting during process programming.


    After analyzing the tolerance of the workpiece, the method of CNC machining is confirmed

    Analysis of tolerance requirements
    We know that no matter whether the workpiece is CNC machining or ordinary machining, there will be certain errors, so the workpiece generally has a reasonable size range that allows the error. For CNC machining of small CNC milling machines, the various errors of the unified process system composed of machine tools, fixtures, cutting tools and workpieces are the source of machining dimensional errors of parts. Therefore, according to the tolerance requirements on the workpiece drawing, it is very necessary to affirm the processing technology to control its dimensional accuracy.
