Precision machining is the process of changing the size or performance of a product workpiece according to the equipment. Depending on the temperature of the workpiece, it is divided into cold drawing and heat treatment. Generally, machining processes that are carried out at room temperature and do not easily cause chemical reactions in the product workpiece are called cold drawing. Generally speaking, the machining process which is higher or significantly lower than the normal temperature and which causes chemical reaction of the product workpiece is called heat treatment. Cold drawing can be carried out according to different mechanical processing and manufacturing methods. It is used for drilling and working pressure processing. Heat treatment is commonly used in heat treatment processes, forging, forging and welding by electric welding.
The production process of precision machining is the whole process of producing and manufacturing goods from raw materials (or semi-finished products processing). It is used for machining manufacturing production manufacturing, including the delivery and storage of raw materials, production site management, preliminary processing, parts processing and heat treatment process, commodity installation and conditioning, painting and packaging.
1, from the hardware point of view, mechanical parts processing is based on a variety of mechanical equipment, such as vehicles, CNC lathes, drilling machines, CNC grinding machines, broaching, CNC machining centers to carry out processing manufacturing, a variety of machinery and equipment original processing precision is not the same, so to achieve a certain degree of precision, when carrying out processing, it is necessary to select the appropriate mechanical processing manufacturing process and mechanical processing manufacturing Machinery and equipment.
2, in terms of software, it is a technical operator, it involves a variety of machine and equipment operator's professional skills. This professional skills include in-depth understanding of machinery and equipment, understanding of machining manufacturing, and its parts and raw materials, etc. This professional skills can be gradually accumulated in the usual work.
