If you want to become a master of CNC machining center operation, you must stand the experience of time and constantly improve your working ability. In the CNC machining industry, CNC machining center programming should be compiled according to the operating characteristics of the machine tool, which is conducive to observation, inspection, measurement, safety, etc. For example, for the same kind of parts, the same processing content, in the vertical processing, and horizontal processing, respectively processing, the program must be different.
CNC machined parts
Proficient in operating CNC machine tools. It takes 1-2 years of study, and the operation is sensitive. Beginners, especially college students, know how to do it, but they just don't listen. In this process, learn: system operation mode, fixture installation, part datum alignment, tool setting, zero point offset setting, tool length compensation, radius compensation setting, tool and handle loading and unloading, tool grinding, part measurement (be able to skillfully use vernier caliper, micrometer card, dial indicator, dial indicator, inner diameter lever gauge), etc.
What can reflect the level of an operator is: horizontal processing, and processing of large gantry (moving beam, top beam). Must have good fixture foundation and measurement technology level. It is difficult to analyze the causes of fixture only qualitatively, but not quantitatively.
In the process of CNC processing in Shanghai, there is a method called thread milling. What is it specifically? Suzhou CNC machining factory adopts thread milling cutter, three-axis linkage of machining center, that is, arc interpolation of X and Y axes, and linear feed of Z axis for thread milling.
Thread milling is mainly used for machining large hole threads and threaded holes of difficult to machine materials. It has the following characteristics:
⑴ Fast processing speed, high efficiency and high processing precision. The cutting tool is generally made of cemented carbide, with fast cutting speed. The manufacturing precision of the cutter is high, so the milling thread precision is high.
⑵ The milling cutter has a wide application range. As long as the thread pitch is the same, a tool can be used for both * * threads and right-hand threads, which is conducive to reducing the cost of the tool.
(3) Milling is easy for chip removal and cooling, and the cutting condition is better than that of tap. It is especially suitable for thread processing of difficult to machine materials such as aluminum, copper and stainless steel,
It is especially suitable for the thread processing of large parts and valuable materials, and can ensure the quality of thread processing and the safety of workpieces.
(4) Since there is no tool front end guide, it is applicable to machining blind holes with short thread bottom holes and holes without undercut.
