Miniature bearing ring grinding process

Grinding can get higher precision and smaller surface roughness, so widely used in bearing grinding. Bearing sleeve ring before finishing after heat treatment, surface hardness is greatly increased, with cutting and other processing methods cannot satisfy the requirement of bearing machining precision, also can't satisfy the requirement of mass production, so must undergo when finishing grinding; Bearing production accounted for 60% of the total labor of grinding, the grinding machine used number accounts for 60% of the total cutting grinding machine, the processing costs accounted for 15% of the total cost. The higher percentage of high precision bearing. 。 Bearing ring grinding process, involving many surfaces of the bearing ring, for these surface, need to grinding a few times, first grinding table surface, which surface such as the first question is we should consider 3. 1 basic knowledge of the process in the actual production, due to the structure shape of parts, geometric accuracy, technology conditions and production quantity different requirements, such as a parts often go through a certain process to its from design to finished parts. Mechanical processing technology personnel must be from the factory, therefore, the existing production conditions and the production quantity of parts, according to the specific requirements of the parts, the guarantee processing quality, improve production efficiency and reduce the production cost under the premise of, on the machining surface of the metal parts choose the suitable processing method, reasonably arrange processing order, scientifically formulate processing process, to obtain the qualified mechanical parts. 3. 1. 1 production process and technological process. Production process of the production process of mechanical products is refers to all the labor process to turn raw materials into finished products. Here refers to the finished product can be a machine, a component, may also be some parts. For machine manufacturing, the production process, including (1) transportation and storage of raw materials, semi-finished products and finished products. の production and technical preparation, such as product development and design, technology and process equipment design and manufacturing, all kinds of raw material preparation and production organization. (3) blank manufacturing and processing. (4) parts machining, heat treatment and other surface treatment. (3) component or product assembly, testing, debugging, paint and packaging, etc. By on, the production process of mechanical products is quite complex. It through the whole route called process is obtained. 2. Process refers to the process change in the production of objects, properties, such as shape, size, relative position, and make it a semi-finished or finished products
