The bearing products specialized production determines the development of NC-specific production of short-term based on the features of the product. The high-precision, low-noise, high-volume, low-cost is the key to the production of motor bearings. Automatic grinding production line of more than 300 domestic production of deep groove ball bearings, CNC technology greatly improve the low noise level of motor manufacturing; fully automatic grinding production line by the micro, small bearing automatic production line to manufacture large bearings automatic production line expansion. Thus the requirements of the numerical control technology is also more diverse, and has become increasingly difficult. An automated production line automatic monitoring of the active measurement technology, machine outside detection technology, automatic error compensation technique, manufacturing quality, NC timely transmission, process control method of quality analysis techniques.

Bearing assembly (bearing finished automatic detection, automatic packaging) automatic line has been plagued by the problem of technological progress. Bearing famous foreign companies, this technology has the actual success for many years. Domestic abroad and use the results are still unsatisfactory. Thus developed bearing assembly automatic production line and bearing grinding automatic production line organic connection to improve the bearing production efficiency and product quality, reducing the number of process flow in the bearing parts of reduce the effects of human intervention, reduce costs, meaning is significant forward. Bearing varieties are many different varieties, automatic assembly line have their own characteristics, the bearing industry is the diversity of the bearing assembly CNC equipment requirements.

Manufacturing and domestic bearing roller is still stand-alone mainly. Bearing famous foreign companies based automatic grinding line continuous production. Currently, a small number of domestic enterprises to introduce a Japanese company manufacturing equipment, expensive, the high cost of equipment depreciation in the domestic promotion. Since the bearing roller is a general requirement in the 1 ~ 2μm, for 0 less than 1μm, and more stringent requirements on surface quality requirements roller. The bearing industry eager CNC equipment industry to provide reliable performance, high-precision bearing roller mill production line and automatic cleaning of rust-proof packaging production line, automatic online automatic detection, automatic feedback compensation processing error. CNC technology has much to offer here. Since the type of roller is divided into: cylindrical roller, tapered roller, needle roller and Spherical Roller four major categories, the CNC industry should be developed according to the different characteristics of the bearing roller and different sizes to adapt to different roller automatic production line.

Bearing manufacturing process, the bearing cage steel plate stamping dies and plastic cage extrusion die, stamping dies, needle roller bearings Drawn cup high-precision mold of rolling element bearing ring the cold roller compacted mold and forging die and bearing assembly mold manufacturing requires efficient, high-precision molds CNC equipment. Made CNC equipment can not meet its functionality and accuracy, high-precision part of the bearing industry mold CNC equipment are imported, some with homemade equipment or retrofit equipment to solve domestic equipment has a huge demand, but the share is low.

Bearing steel ball up rolling bearing industry. Ball production process after that the steel ball automatic cleaning, automatic visual inspection (automatic elimination of non-conforming product), automatic anti-rust, count packaging abroad is also complete an automated production line. Domestic bearing industry has invested a lot of energy, after ten years of efforts, has made some progress, but there is still a large gap compared with the state-of-the-art level. Ball certain accuracy requirements reached nm level, the surface quality requirements are more stringent than the bearing roller and volume requirements of the equipment of high efficiency, high precision, high reliability and high cleanliness. Thus, in this area, bearing great demand, CNC equipment industry can accomplish a great deal.

With the continuous promotion of high technologies and advanced applicable technologies to transform traditional bearing manufacturing model and in-depth, digital technology has become the development direction of the bearing industry, bearing processing equipment using digital technology into the bearing of choice for enterprises to improve equipment levels. At the same time, high-precision, high-efficiency, automatic production line has good prospects for development.

Bearing industry are generally concerned about the problems and requirements of CNC equipment are as follows:

High reliability and timely and good after-sales service. This requirement is not unique in the bearing industry, but at this point of the bearing industry expressed strong. Mainly due to the production of the bearings industry is characterized by continuous, high-volume production lines, a device, a CNC automatic spot problems, it will cause the entire production line downtime, loss. Promote domestic development of CNC automatic line disadvantage is largely due to the reliability of the equipment and after-sales service is not in place.
