Changzhou Machining tells you what machining is?

Changzhou Mechanical Processing informs you what is mechanical processing? Machining is a process in which the external dimensions or functions of a workpiece are modified using a processing machine. According to the temperature state of the workpiece being processed, it is divided into cold processing and hot processing. Generally, cold processing is performed at room temperature without causing chemical or physical phase changes to the workpiece. Generally, processing above or below normal temperature can cause chemical or physical phase changes in the workpiece, which is called thermal processing. According to different processing methods, cold machining can be divided into cutting and pressure machining. Hot working commonly includes heat treatment, forging, casting, and welding. In addition, cold and heat treatment is often used during installation. For example, when installing bearings, the inner ring is often cooled in liquid nitrogen to shorten its size, while the outer ring is properly heated to expand its size, and then installed together. The outer ring of a train wheel is also heated and sheathed on the substrate, ensuring a strong bond when cooled

In terms of production process and technological process:

The production process refers to the entire process of making products from raw materials (or semi-finished products). For the production of machines, it includes the transportation and storage of raw materials, preparation for production, production of blanks, processing and heat treatment of parts, installation and commissioning of products, painting and packaging, etc. The content of production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a production system with input and output. It can make the management of enterprises scientific and make them more resilient and competitive.

During the production process, the process of directly changing the shape, scale, and function of raw materials (or blanks) into products is called a process process. It is the first part of the production process. Such as casting, casting, and welding of blanks; Heat treatment that alters the function of the material; The machining of parts, etc., is attributed to the technological process. The technological process is composed of one or several sequential processes.
