The processing process of the CNC mold processing center refers to the processing order of parts processing. The content includes specific processing steps, workplaces, tools and standards, and the content of the sectarian and other special requirements, the processing coordinate position of the processing coordinate Process maps, etc. The part processing process is the basis for modifying the CNC processing procedure. The parts that are processed on the CNC machine should have a corresponding processing process.
CNC mold processing centers should be flexibly divided according to the structure, material characteristics, clamping positioning, machine tool function, number of processing parts, and the number of devices.
When processing parts, not all processing processes are suitable for completion on CNC machine tools. Therefore, before processing parts, the need for specific analysis of the parts drawings, and formulating a reasonable processing plan according to the conditions of the equipment, the condition of the tool, and the condition of the tooling fixture. Therefore, it is necessary to separate the contents of the procedures for CNC processing, and which procedures are not suitable for CNC processing. There are several situations:
1. The content of suitable CNC mold processing center. There are generally the following parts that can be processed by CNC milling machines and processing centers.
A. Plane parts (each processing surface is plane, or can be developed into plane parts.) Plane parts are the most common and simplest parts of processing in processing. Therefore Essence
B. Turf parts (processing surfaces with space surfaces, such as impeller, blades, propeller, etc.) The processing surface of the curved parts cannot be expanded as a plane. During processing Class parts generally use tri -axis linkage CNC machine tool processing. If the curved surface is more messy and the passage is narrow, it will hurt the adjacent surface or the required knife. It is more appropriate to use a four -axis or five -axis CNC machine tool.
C. Change the diagonal angle parts (the angle of the processing surface and the horizontal plane shows the parts that have changed successively.) The diagonal angle processing surface of the oblique parts cannot be expanded as a plane. During processing, the processing surface and milling cutter are touched instantly For a straight line, a four -axis or five -axis CNC machine tool should be selected for swinging. When processing is processed by a three -axis CNC machine tool, two -axis and half -like processing can be adopted.
D. Box parts (box parts refer to one and one or more hole system, there are certain cavities or air engine boxes inside. The orientation accuracy has very strict requirements. The processing of the boxes of the box generally needs to pass the process, drill, expand, 镗,,, full, attack, or milling thread.
2. Not suitable for the content of the CNC mold processing center. Including the contents that the general machine tool cannot be processed; the content that is difficult to process of the universal CNC mold machine, and the quality is difficult to ensure; the processing efficiency of general CNC mold machine tools, and the work of working hard to operate the labor intensity of the workers. A. For a long time adjustment of the machine, it is necessary to use the dedicated workflow in harmony. B. The processing parts are scattered, the requirements are repeatedly installed, and the process content of the original point is repeatedly set. C. Facial wheels processed according to certain manufacturing basis (such as models). The main reason for this type of parts is not suitable for the use of CNC machining is to obtain data difficulties. It is easy to confront the inspection according to the confrontation, which increases the difficulty of programming.
