Bearing steel, as a high-strength, wear-resistant special steel, is widely used in the manufacture of various mechanical bearings, such as balls, rollers and bearing rings. Its processing process requires not only high precision, but also excellent surface quality. Therefore, bearing steel processing technology is particularly important. This article will outline the main technologies used in bearing steel processing.
Machining technology is one of the main methods of bearing steel processing. This includes a variety of processes such as drilling, turning, milling and grinding. Drilling is a conventional processing method for bearing steel, which is used to make holes inside bearings. During the drilling process, appropriate tools and coolants should be selected according to the hole diameter and depth, and process parameters such as cutting speed, cutting depth and feed speed should be strictly controlled to ensure the accuracy of the hole diameter.
Turning is another common processing method for bearing steel. It is mainly used for the processing of the outer circle, inner hole and end face of the bearing. Appropriate cutting speed, feed speed and tool grinding method should be used during turning to ensure good surface quality and high precision of the processed bearing. In addition, milling is also widely used in the processing of bearing steel, mainly for processing complex shapes such as grooves and bosses of bearings.
Grinding is a common way of fine processing in bearing steel processing. It is mainly used to improve the finish and precision of the bearing surface, reduce the surface roughness, and thus improve the friction performance and wear resistance of the bearing. During the grinding process, it is necessary to select suitable grinding wheels, dressing tools and usage methods, and control parameters such as grinding force and surface roughness to achieve the desired processing effect.
In addition to machining technology, hot processing technology also plays an important role in bearing steel processing. Hot processing technology mainly includes processes such as forging, hot rolling and hot extrusion. These processes heat the bearing steel to a certain temperature and then apply external force to make it plastically deform, so as to obtain bearing parts of the desired shape and size. Hot processing technology can not only improve the strength and toughness of bearing steel, but also improve its internal organization and performance.
In summary, bearing steel processing mainly uses machining technology and hot processing technology. These technologies have their own characteristics and complement each other, and together constitute a complete system of bearing steel processing. In the actual processing process, appropriate processing technology and process parameters should be selected according to the specific requirements and processing conditions of bearing steel to ensure that the processed bearing parts have excellent quality and stable performance.
