In bearing manufacturing process, bearing maintains a steel plate stamping die and plastic keep frame of extrusion die, all kinds of rolling body stamping mould, needle bearing outer ring with high precision mould, s tamping mould and rolling bearing collar cold forging die and bearing assembly mould etc processing manufacturing, all need efficient, high precision mould numerical control equipment. Because of home-made numerical control equipment can t meet its function and precision, bearing industry of high precision mould part of numerical control equipments are imported, and part of the use homemade equipment or modification of equipment to solve, domestic equipment has the huge demand, but the present share comparatively low.

Bearing products specialized production according to the characteristics of the products determines the development of numerical control special production short. High precision, low noise, high-volume, low-cost production is the key to motor bearing. The current domestic production of the article has 300 or so deep groove ball bearing grinding automatic production line, numerical control technology has greatly increased the low noise of motor manufacturing level; Fully automatic grinding at present by micro, small production line of the bearing automatic production line for the manufacturing medium bearing automatic production line extensions. Thus the numerical control technology requirements for greater diversification, difficulty also is more and more big. In automatic production line on active measurement technology, detection technology, automatic cake error compensation technology, manufacturing quality automatic monitoring,roll bearings nc timely transmission, quality analysis technology, process and control method.
Bearing assembly (including bearing the automatic test finished product, automatic packaging) automatic line has been bothering technology progress of difficult problems. In the foreign famous bearing company, the technology has actual successfully used for many years. By introduced from abroad and domest ic, and using effect are still not satisfying. So r&d bearing assembly to be automatic production line, and the automatic production line and bearing grinding organic connection, to improve the bearing manufacturing efficiency and product quality, reduce process flow in the number of bearing parts, reduce the influence of the intervention, reduce cost, meaning is remarkable. Because many kinds of bearings, different varieties, automatic assembly line have different features, thus bearing industry on the bearing assembly of the numerical control equipment to the diversity of the proposed requirements.
The roller bearing manufacturing domestic is mainly single. Foreign famous bearing company is grinding automatic line continuous production. At present,bearing roller bearings the domestic enterprise introduced a few Japanese company manufacturing equipment, because the price is expensive, equipment depreciation cost high and not in the domestic promoted. Due to the requirements of the roller bearing commonly in 1 ~ 2 μ m, for 0 level in 1 μ m roller requirements within, and the surface quality of the stricter requirements. Bearing industry is hoping to numerical control equipment industry can provide stable and reliable performance, high precision roller bearing automatic grinding production line and automatic cleaning rust packaging production line, automatic line in the realization of automatic detection, automatic feedback processing error compensation. So the numerical control technology in here go a long way. Because of the type of roller is divided into: cylindrical roller bearing, tapered roller, needle and spherical roller four major categories, numerical control industry should be based on the different characteristics of the roller bearing and different size to develop in different roller automatic production line.
Bearing s teel ball is bearing industry use most rolling body. The production process of steel ball after that steel ball automatic cleaning, automatic appearance test (automatic eliminate nonconforming), automatic rust and count packaging, abroad is in automatic production line on the finish. Domestic bearing industry into a lot of energy, after several years of effort, and made some progress, but compared with advanced level is still a big gap. Because some of the steel ball accuracy requirement has reached nm level, the surface quality requirements of the roller bearing more than strictly, and batch big, high efficiency, high precision, request equipment with high reliability and high cleanness. Therefore, in this field, a big demand bearing industry, nc equipment industry can go a long way.
As with high and new technology and advanced applicable technology to transform traditional bearing manufacturing mode and the further promotion of deep, digital technology has become the development direction of the bearing industry, using digital technology bearing processing equipment became bearing enterprises to improve equipment level of choice. At the same time, high precision, high efficiency, special automatic production line has good development prospect.china bearing company
