Bearing industry development and the requirements of CNC equipment

In the bearing manufacturing process, bearing cage steel stamping mold and plastic cage extrusion mold, a variety of rolling body stamping mold, needle roller bearings with stamping outer ring high-precision molds, bearing collar cold milling molds and forging molds, as well as bearing assembly molds and other processing and manufacturing, are required to efficient, high-precision mold CNC equipment. Due to the domestic CNC equipment can not meet its function and accuracy, bearing industry part of the high-precision mold CNC equipment are imported, part of the homemade equipment or transformation equipment to solve the problem of domestic equipment has a huge demand, but the current share of low.
Specialized production of bearing products determines the characteristics of the product according to the development of CNC special production of short lines. High precision, low noise, high volume, low cost is the key to the production of motor bearings. At present, there are about 300 domestic production of deep groove ball bearings of automatic mill production line, CNC technology has greatly improved the manufacturing level of low-noise motors; automatic mill production line is currently micro, small bearings by the automatic production line to the manufacture of medium and large bearings in the expansion of the automatic production line. As a result, the requirements for CNC technology are becoming more and more diversified and difficult. In the automatic production line active measurement technology, off-machine testing technology, automatic error compensation technology, automatic monitoring of manufacturing quality, CNC timely transmission, quality analysis technology and other process control methods.
Bearing assembly (including automatic inspection of finished bearings, automatic packaging) automatic line has been plagued by technical progress of the problem. In foreign famous bearing company, this technology has been successfully applied for many years. And the domestic rely on the introduction of foreign countries, and the use of the effect is still unsatisfactory. Therefore, the research and development of bearing assembly automatic production line, and bearing grinding automatic production line organic connection, for improving the production efficiency of bearings and product quality, reduce the number of bearing parts in the flow of processes, reduce the impact of manual intervention, reduce costs, the significance is significant. Due to the many varieties of bearings, different varieties, automatic assembly line has its own characteristics, and thus the bearing industry on the bearing assembly of the diversity of CNC equipment requirements.
Bearing roller manufacturing domestic is still dominated by a single machine. Famous foreign bearing companies are grinding automatic line continuous production. At present, a small number of domestic enterprises introduced the Japanese company's manufacturing equipment, due to the high price, high depreciation cost of equipment and can not be promoted in the country. Due to the general requirements of bearing rollers in 1 ~ 2μm, for the 0-level roller requirements within 1μm, and the requirements of the surface quality is more stringent. Bearing industry urgently hope that the CNC equipment industry can provide stable and reliable, high-precision bearing roller automatic grinding production line and automatic cleaning and anti-corrosion packaging production line, in the automatic line to realize automatic detection, automatic feedback to compensate for processing errors. Therefore, CNC technology here is a big difference. As the types of rollers are divided into: cylindrical rollers, tapered rollers, needle rollers and spherical roller four categories, CNC industry should be based on the different characteristics of bearing rollers and different sizes to develop adapted to different roller automatic production line.
Bearing steel ball is the most used rolling body in the bearing industry. Steel ball production after the process that steel ball automatic cleaning, automatic appearance inspection (automatic rejection of substandard products), automatic rust prevention, counting and packaging, foreign countries are also completed in the automatic production line. The domestic bearing industry has invested a lot of energy, after more than ten years of efforts, has made some progress, but compared with the advanced level there is still a big gap. As some precision requirements of steel balls have reached nm level, the requirements of surface quality are more stringent than bearing rollers, and the batch size is large, which requires high efficiency, high precision, high reliability and high cleanliness of the equipment. Thus, in this area, the bearing industry is in great demand, CNC equipment industry can make a big difference!
With the use of high-tech and advanced technology to transform the traditional bearing manufacturing model of the continuous promotion and depth, digital technology has become the direction of development of the bearing industry, the use of digital technology bearing processing equipment has become the first choice of bearing enterprises to improve the level of equipment. At the same time, high-precision, high-efficiency, specialized automatic production lines have good prospects for development.
