What are the requirements for the development of KOYO bearing industry and CNC equipment?

In the manufacturing process of KOYO bearing, KOYO bearing cage steel plate stamping mold and plastic cage extrusion mold, stamping mold of various rolling bodies, needle roller KOYO bearing stamping outer ring high-precision mold, KOYO bearing ring cold rolling mold and forging mold and KOYO bearing assembly mold and other processing and manufacturing, All need high efficiency, high precision die numerical control equipment. Because domestic numerical control equipment can not meet its function and accuracy, part of the high-precision die numerical control equipment of KOYO bearing industry are imported, and some of them are solved by homemade equipment or modified equipment. There is a huge demand for domestic equipment, but the current share is low.

The specialized production of KOYO bearing products determines the development of CNC special production line according to the characteristics of products. High precision, low noise, large quantities and low cost are the key to the production of motor KOYO bearings. At present, there are about 300 automatic grinding production lines for deep groove ball KOYO bearings in China. Numerical control technology has greatly improved the manufacturing level of low noise motor. At present, the automatic mill production line is expanded from the automatic production line of miniature and small KOYO bearings to the automatic production line of manufacturing medium and large KOYO bearings. As a result, the requirements of numerical control technology are becoming more and more diverse and difficult. In THE automatic production line, active measurement technology, out-of-machine detection technology, automatic error compensation technology, automatic manufacturing quality monitoring, CNC timely transmission, quality analysis technology and other process control methods.

The automatic line of KOYO bearing assembly (including automatic detection and automatic packaging of finished products of KOYO bearings) has always been a difficult problem plaguing technical progress. In the famous foreign KOYO bearing company, this technology has been successfully applied for many years. But the domestic relies on the foreign introduction, and the use effect is still not satisfactory. Therefore, the research and development of KOYO bearing assembly automatic production line, and organic connection with the grinding automatic production line of KOYO bearings, to improve the production efficiency and product quality of KOYO bearings, reduce the number of KOYO bearing parts in the process flow, reduce the impact of manual intervention, reduce costs, significance is significant. Because there are many varieties of KOYO bearings, different varieties and automatic assembly lines have their own characteristics, the KOYO bearing industry has put forward requirements for the diversity of CNC equipment assembled by KOYO bearings.

The manufacturing of KOYO bearing roller in China is still mainly single machine. The famous foreign KOYO bearing company is continuous production with automatic grinding line. At present, a small number of domestic enterprises have introduced manufacturing equipment from Japanese companies, which cannot be promoted in China due to the high price and high depreciation cost of equipment. Because the general requirements of KOYO bearing rollers are in the range of 1 ~ 2μm, the requirements for grade 0 rollers are within 1μm, and the requirements for surface quality are stricter. KOYO bearing industry urgently hopes that the CNC equipment industry can provide stable and reliable performance, high precision KOYO bearing roller automatic grinding production line and automatic cleaning anti-rust packaging production line, in the automatic line to realize automatic detection, automatic feedback compensation processing error. So numerical control technology is very useful here. Because the types of rollers are divided into four categories: cylindrical rollers, tapered rollers, needle rollers and spherical rollers, CNC industry should develop automatic production lines suitable for different rollers according to the different characteristics and different sizes of KOYO bearing rollers.

KOYO bearing ball is the most used rolling body in the KOYO bearing industry. The final process of steel ball production is automatic cleaning, automatic appearance detection (automatic rejection of unqualified products), automatic rust prevention, counting and packaging, which is also completed in automatic production line abroad. The domestic KOYO bearing industry has invested a lot of energy. After more than ten years of efforts, it has made some progress, but there is still a large gap compared with the advanced level. Because some of the precision requirements of the steel ball have reached nm level, the surface quality requirements are more strict than the KOYO bearing roller, and the batch is large, which requires the equipment to be high efficiency, high precision, high reliability and high cleanliness. Therefore, in this field, the demand of KOYO bearing industry is great, and the CNC equipment industry can be great.

With the continuous promotion and deepening of the transformation of traditional KOYO bearing manufacturing mode with high and new technology and advanced applicable technology, digital technology has become the development direction of the KOYO bearing industry. The KOYO bearing processing equipment using digital technology has become the first choice for KOYO bearing enterprises to improve the equipment level. At the same time, high precision, high efficiency, special automatic production line has a good development prospect.
