precision machining of the production process differences

Detail machine general mechanical parts processing and precision machining of the production process differences

Mechanical equipment parts processing is the whole process of changing the specifications or characteristics of the workpiece according to the equipment. According to the temperature condition of the workpiece, it can be divided into cold drawing and heat treatment processes. Generally in the normal temperature state of mechanical processing and not easy to lead to chemical reactions of the workpiece called cold processing. In general, the whole process of machining that is higher than or significantly lower than the normal temperature will lead to the chemical reaction of the workpiece is called the heat treatment process. Cold processing can be divided according to different machining methods. It can be used for milling as well as pressure production processing. Heat treatment processes are commonly seen in heat treatment methods, calcination, calcination and arc welding.

Mechanical equipment parts processing

The production process of high precision machining refers to the whole process of producing and processing products based on raw materials (or production and processing). It is used for machining production processing, including the transportation and storage of raw materials, manufacturing construction site management, preliminary processing, parts processing and heat treatment methods, product installation and adjustment, painting and packaging. From the perspective of system configuration, the machining of mechanical equipment parts is based on a variety of industrial equipment, such as cars, machining centers, planers, CNC grinders, and broaching machines, as well as CNC machining. Heart management center to carry out production and processing production and processing, all kinds of machinery and equipment of the original processing accuracy is not the same, so to ensure the accuracy, in the development of production and processing conditions, it is necessary to choose the appropriate mechanical processing production process also have mechanical processing machinery and equipment.


In order to better ensure the precision of machining, it is necessary to carry out primary processing and finishing separately. Due to the condition of initial processing, many workpieces are subjected to cutting amount, clamping force, heat, it is easy to cause surface hardening, the workpiece has a very large internal stress, if the finishing and roughing is constant, the precision of precision machining parts after finishing will be with the stress field again throughout, fast will be lost. For some parts with high machining accuracy. Low temperature heat treatment or tempering heat treatment should be carried out after primary processing and before finishing. Remove the internal stress.

Reasonable selection of machining machines and equipment. The important process flow of primary processing is to cut off most of the remaining amount of production and processing, and does not require higher processing accuracy. Therefore, the roughing machining center must only be high-power, low-precision production and processing. Finishing must be done in more precise machining. Heart. In different processing. To carry out rough and finish machining, not only can make full use of the characteristics of the machine equipment, but also improve the service life of the precision machine tool.
