CNC precision machining is a machining technology in today's mechanical manufacturing industry. It inputs the CNC program of the processed parts into the CNC machine tool, and the machine tool automatically processes the working parts after receiving the CNC program. CNC machining technology can effectively solve complex, small and medium-sized, and variable hardware part machining schemes to meet the needs of modern production. The CNC machining process includes tool selection, cutting parameters, and tool methods.
CNC machining technology is the core content of CNC programming. Choose a CNC program with less processing time and smaller tool modes to achieve efficient and high-quality products. CNC machining technology can be divided into rough machining, transparent angle machining, and fine machining. Large tools should be selected for rough machining of non-standard parts, and a large number of working components should be quickly cut off and rough machining should be started under high power of the machine tool. The principle of tool selection is mainly to consider whether the arc of the product is too small. After selecting the tool, determine the length of the tool. In principle, the length of the tool should be greater than the machining depth.
The knife we use has a viewing angle and usually needs to clear the angle on the step axis. The milling cutter groove needs to be cleared of angle.
The benefits of doing this are: firstly, the grinding shaft of the grinder quickly retracts the grinding wheel, which will not grind to the end face and affect the length; secondly, the assembly fully contacts the end face, resulting in smaller end face runout.
In the current manufacturing industry, CNC machining is a very important machining method, and many enterprises and manufacturers are using this machining method. The main reason is that CNC machining has a short processing time and high accuracy. Compared to traditional mechanical processing, it can save more time. It can achieve higher precision and more complex structures. Automotive component processing.
At present, several domestic hardware manufacturing enterprises in China are engaged in small-scale and dispersed hardware product processing. Although CNC machining equipment has reached the industry level, the quality and productivity of product production heavily depend on the strength of the machining masters themselves. Therefore, there are few technical personnel, leading to a shortage of talent in the field of intelligent manufacturing and slow industry development.
CNC precision parts processing generally adopts self-made or outsourced manufacturing, and the enterprise determines based on its own situation. For example, more special processing techniques such as electroplating, oxidation, sandblasting, screen printing, laser engraving, etc. require finding a professional CNC machining factory for processing and manufacturing.
