In revitalize the stock efficiency, precision machinery industry determines its particular role. Raw material and energy prices, not reduce the production cost, only by improving production efficiency, increase the added value of the products. If vigorously promoted by the precision machinery, application of nc machine tools, can greatly improve the efficiency.
Citic built cast machinery manufacturing industry researcher FengFuZhang thinks, bearing is one of the machine equipment transmission mechanism, it is an important part for supporting shaft, guiding axis rotation movement. Machine equipment operating precision, performance, life and economic benefit directly with bearing performance has the close relation, and focus on.

    According to the current bearing enterprise shaft grind technology, though smaller, not in the domestic bearing industry, ranking front, but shaft grind technology mainly produces aerospace and machine tools with high-end bearing, not with other enterprise general product competition, so a shaft grind technology in terms of technology in China, the market leading position relative to other bearing enterprise has a bigger superiority.
