Domestic 10m long and heavy duty ball screw developed successfully

The largest-scale "whole-grinding 10m long and heavy-duty Ball Screw" in China is currently successfully developed in Qinchuan Group Hanjiang Machine Tool Co., Ltd. The successful development of this specification ball screw has filled the gap in the field of domestic rolling functional components.

For a long time, due to various factors such as technical equipment, the ball screw market with a domestic value of more than 5 meters and high added value has been basically occupied by foreign companies. Hanjiang Machine Tool Co., Ltd. is the main manufacturer of domestic thread grinding machines and ball screws. Although it has made breakthroughs in the research and development of 3 m, 4 m and 5 m CNC screw grinders, and has a large market share in China, it is still a blank in the 5~10 m integrally Ground Ball Screw market.

Thread grinder is a special equipment for the production of rolling functional components. For this reason, Hanjiang Machine Tool, which is the director unit of the Rolling Functional Components Association, has continuously increased its investment in scientific research by virtue of its unique technological advantages. Based on the original products, it has successfully developed. Different sizes of CNC screw grinders have resulted in a complete series of seven specifications. So far, Hanji Company is the only one in China with HIY-022 (coarse screw), HIY-05 (1 meter screw), HIY-025 (1.5 meter screw), HIY-028 (3 meter screw), HIY-012 (5m screw) full rolling screw dynamic maintenance equipment rolling function component manufacturer.

It is understood that Hanjiang Machine Tool will focus on improving the production capacity of long lead screws and large leads of more than 3 meters. During the “Eleventh Five-Year Plan” period, the company will invest 250 million yuan in technical transformation funds, which will make the annual production capacity of ball screws reach 400,000, the rolling linear guides reach 200,000 meters, and the production and sales revenue will reach 800 million yuan.
