At this stage, the thread processing types of mechanical thread parts in the market mainly include internal thread, single thread, variable pitch thread, external thread, multi-thread thread, and fixed-pitch thread.
In the past, the machine tool processing technology was based on the thread line cutting and processing of parts. However, mechanical processing is based on turning processing technology, which drives the tool through a mechanical transmission belt to realize part processing.
When processing mechanical threaded parts, CNC machining centers are often used for parts processing. This is because CNC machining center processing technology can greatly improve the machining accuracy of mechanical threaded parts, while ensuring the safety of parts processing and the quality of parts,improve the processing efficiency of threaded parts.
The lathe processing method can effectively improve the quality of parts processing and greatly shorten the processing cycle of parts. When the CNC machining center processes mechanical threaded parts, it needs to apply coordinate, size measurement and other technical means to grasp the size and position of mechanical threaded parts in a multi-directional manner, for example, the points, lines, and surfaces of mechanical screw parts Equal azimuth angle, these data are an important basis for realizing reasonable programming, because when CNC machining of mechanical thread parts, it is necessary to avoid large accumulation of errors. In order to achieve this goal, it is often necessary to modify some of the dimensions in the local scatter annotation.
When applying numerical control technology, it is necessary to ensure that the use of tool paths can be as simple as possible, so that the CNC machining center can carry out the cutting program in an orderly manner, taking into account that the CNC machining center should avoid contour errors when processing mechanical thread parts. Therefore, in the processing process, it is also necessary to ensure that the linear contour of the part can be parallel to the coordinate axis, so as to ensure that the mechanical threaded parts can be processed with high precision. It should be noted that when dealing with the inflection points in the mechanical threaded parts, Ensure that no right-angle transition occurs.
