Hanjiang tool modern broaching tool manufacturing base broke ground
At 11 o'clock on the morning of October 20, with the firecracker Qi Ming and the first shoveling of construction machinery, the investment of more than 10 million yuan, planning and design of 5800 square meters of Hanjiang tools modern broaching tool factory broke ground in the new site. Comrade Wang Chengzhi, chairman and party secretary of Hanjiang Tools, personally ignited the first firing of the salute. The groundbreaking of the new factory building marks a new development stage for the improvement of Hanjiang tool broaching tool technology, modern equipment and manufacturing level. It also shows that Hanjiang tools have been transformed and upgraded, and they have continued to innovate. They have taken new steps in the direction of creating a world-class complex tool enterprise. With the development of the equipment manufacturing industry, more and more broaching methods have been adopted. Compared to milling, the machining efficiency, accuracy and dimensional stability of broaching are much higher than milling. Depending on the material being processed, the tool material is gradually replaced by powder metallurgy high speed steel and powder metallurgy cobalt high speed steel from the previous ordinary high speed steel and cobalt high speed steel. According to the different machine tools used, it is divided into horizontal broaching and vertical broaching. Depending on the size of the profile and the length of the broaching, the broach is designed with thick drawing (for delamination and large-scale broaching for blank removal) and semi-finishing (for progressive or same profile) Type broaching), fine-drawing structure (using the same profile broaching consistent with the workpiece profile). Due to its high precision, complex profile and difficult broach processing, only a few tool factories in China can process it. At present, the broaches used in steam turbine plants and aero engine plants are mainly imported, and a set of broaches has three to ten Support, ranging from tens of thousands to millions of dollars. According to the planning and design, the Hanjiang tool broaching tool technical transformation project is an important part of Hangong's “Twelfth Five-Year†technical transformation. With the modernization of factory facilities and world-class high-precision equipment, knives and tools will be broached. The manufacturing process level and production scale will reach the international advanced level. After it is completed and put into production, the project will become an important base for Hanjiang tools to pursue high-quality and high-end manufacturing. It will become a production center and service center for domestic and foreign aviation engine, automobile, new energy and other industries, greatly improving market supply and service response capabilities. This will further enhance the high-end competitiveness of Hanjiang Tools. The new plant will be completed in June 2012.
