At 11 o'clock on the October 20, with the first shovel the rise of firecrackers and construction machinery, invest in more than 1,000 yuan, planning and design of the 5,800 square meters of Hanjiang Tool modern broaching tool plant ceremoniously broke ground on a new site. Hanjiang Tool chairman and party secretary Wang Zhi comrades personally lit first ring starts Salute. The ground-breaking of the new plant, marking the Han River tools broaching cutter technological transformation progress, modern equipment and manufacturing level has entered a new stage of development. Also shows that the the Hanjiang abrasive tools transformation and upgrading, innovation has taken a new step in the direction of creating a world-class corporate complex tool.

With the development of the equipment manufacturing industry, the broaching method more and more. Compared with milling, broaching processing efficiency, accuracy and dimensional stability is much higher than milling. Processing different materials, cutting disc material by the ordinary high-speed steel high-speed steel and cobalt have been gradually replaced by high-speed steel powder metallurgy high-speed steel, cobalt and powder metallurgy. They use a different machine is divided into horizontal broaching and vertical broaching. Depending on the length of its type face size and broaching, broach design for blooming to remove a large margin hierarchical and gradually became broaching), semi-refined crude pull (pull (had become the style or the same profile broaching), finely drawn structure (profile piece silhouette with broaching). Because of its high precision, surface-type complex, difficult to broach processing, are only a small number of tools factory capable of processing used in the steam turbine plant and aero-engine plant Broach mainly imports, a broach to tens branch, worth a few million to several hundred million dollars.
