In recent years, Qiji Machine Tool has been actively committed to independent innovation, aiming at improving the numerical control output rate of products. It has developed more than 10 new products every year. It has successively introduced heavy-duty CNC floor-milling boring machines, CNC double-column vertical lathes, CNC horizontal gantry and gantry. The five-axis linkage hybrid machine tool has high-tech equipment with advanced domestic and international standards. At present, the company has developed 115 new products, of which 34 are close to the international advanced level, 51 products fill the domestic gap, and 19 awards such as the provincial and above scientific and technological progress awards, the output value of new products averages over 50%; The numerical control rate of heavy-duty products has reached more than 60%; more than 90% of new CNC products have reached the advanced level of international contemporary similar products.
Qiji Machine Tool actively exerts its own advantages and seizes the high-end market of equipment manufacturing. Its domestic product with independent intellectual property rights, the floor milling and boring machine, has maintained a domestic market share of more than 85%, making it the world's largest CNC floor-standing milling and boring machine manufacturing base. Over the past few years, the company has provided more than 500 sets of major equipment for construction services in key areas such as national defense, military industry and aerospace.
It is understood that the "2008 First China Equipment Manufacturing Gold Awards" campaign is aimed at standardizing the guiding and revitalization of the sound development of the equipment manufacturing industry, comprehensively grasping and analyzing the development status of China's equipment manufacturing industry, and further standardizing the market economic order of the equipment manufacturing industry. Promote technological innovation and technological advancement. Through the company's self-recommendation, expert review, and major industry users' voting, the company evaluates the brand of machine tool companies that are engaged in production and business activities in China. The evaluation will focus on ten aspects of corporate governance, enterprise innovation, profitability, brand cultivation, etc. After the evaluation, the review team also conducted a comprehensive quantification, modeling and guiding description of the evaluation results, and wrote a summary of the evaluation activities. The report and the "2008 China Equipment Manufacturing Industry Development White Paper" will be submitted to the General Office of the State Council, the Ministry of Commerce and relevant authorities.
Angular contact ball bearings mainly bear large unidirectional axial load. The greater the contact angle, the greater the load bearing capacity. The material of cage is steel plate, brass or engineering plastics. The forming method is stamping or turning. It is selected according to the bearing form or using condition. Others include combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions.
