The honing machine JWH-3000 has made significant contributions to the country's efforts to tackle the core technology of high-speed rail.

In terms of the core technology of high-speed rail, high-speed hollow axles have always been a foreign monopoly technology. In 2014, Jinxi Axle Co., Ltd., the actual holding company of China National Ordnance Industry Group, overcame the technical difficulties of high-speed rail axles in the four years from 2010 to 2014, and finally, China's high-speed rail had its own axle. As a leader in deep hole honing machines in China, our company's engineers and Jinxi Axle Company have organized more than ten technical seminars to develop small hole deep hole honing machines specifically for axles, solving the problem of machining accuracy for high-speed hollow axles.
