The Introduction of Terminology of Cutting Technology in Bearing Blanks
Cutting technology is an important part of the bearing blanks production process, and has always been the focus of the bearing blanks industry. In the continuous development and progress of the process, the cutting technology of bearing blanks is gradually perfected, so that the bearing blanks can be manufactured with high precision, high quality and low cost. In this paper, the basic concepts and terminologies of bearing blanks cutting technology are introduced.
The cutting technology of bearing blanks refers to the process of cutting bearing blanks from a piece of metal into a required shape, size and precision. The cutting technology includes various methods, such as cutting, grinding, local quenching and other methods. Generally speaking, it includes several steps: material preparation (annealing, normalizing and quenching process), blank cutting (blank cutting according to the design of bearing blanks), heat treatment and finishing.
The cutting technology of bearing blanks is mainly divided into two categories: cutting and punching. The cutting technology is used to cut the bearing blank into a certain shape or size by using cutter or cutting tools, while the punching technology is used to punch the bearing blank into a certain shape or size by using a die presser. The shape of the blank cut by this technology depends on the cutting tool selected, including flat blade, round blade, precise blade and wing blade, etc. The precision of the blank depends on the cutting parameters and the machining accuracy, such as speed, table spacing, cutting angle, feed rate and other parameters.
The forming technology of bearing blanks is mainly divided into forging, rolling and forging technology. The forging and rolling technology is used to produce bearing blanks with complex shapes, such as spheres, ellipses, polygons and other shapes, and the parameters of rolling , forging and other processes will affect the shape and size of the blanks. In addition, the shaping technology of bearing blanks also includes quenching, normalizing and other heat treatment technologies, which will affect the microstructure,s hardness and toughness of the bearing blanks.
In addition, there are also abrasive machining and electro-discharge machining technology in the cutting technology of bearing blanks. Abrasive machining mainly includes grinding and sandblasting, which can make the surface of bearing blanks smoother, higher in accuracy and with better surface quality. Electro-discharge machining technology can also help to get higher precision and surface quality, but it is mainly used in processing complex geometric structure of bearing blanks.
Overall, the cutting technology of bearing blanks can be divided into cutting, punching, forming, abrasive machining and electro-discharge machining technologies. As Technology of bearing blanks is constantly improving and upgrading, the related cutting technology is also continuously changing and exploring. With the better understanding of the cutting process, the cutting technology of bearing blanks can bring the production of bearing blanks a more scientific, stable and efficient improvement.
