The first station mechanical axis CNC milling and boring machine passed the acceptance

By the Jinan Machine Tool Group Co., Ltd. is responsible for research and development of China’s first mobile portal Ssangyong axis CNC milling machine machine has passed the State. China Machinery Industry Federation and the State Council Three Gorges Project Construction Committee of three major equipment manufacturing engineering inspection team late last month at the Liaoning Anshan Heavy Machinery Co., Ltd. jointly organized the five-axis CNC milling machine products, appraisal meeting and demonstrations.

Second, successful economic development of this machine sets XKV2745 × 200 CNC boring and milling machine, breaking the monopoly of foreign technology to solve the country needed large-scale power generation turbine blade industry processing equipment problems.

Previously produced in our five-axis NC machine tool as the spindle to spindle head, the output torque is small, mainly used for small parts machining non-ferrous metals. The large pump blades, ship propellers, aircraft propellers, turbine blades turn group, high-precision stamping dies and other processing parts, large diameter, processing area, allowances and more, to adopt the high-power, high torque mechanical drive type five-axis linkage milling head. However, this mechanical transmission five-axis of the core technology only for Germany, France, Italy and a few developed countries to master.

At present, China’s large-scale hydropower facilities, water transportation equipment, ship propellers, car mold, surface precision complex, heavy cutting, the state investment projects focused on the South, the Three Gorges water conservancy, natural gas based equipment, key parts processing, machine tools that are urgently needed. In particular, the processing of large turbine blades all dependent on imported equipment, and domestic market demand is quite large.
Therefore, developed with independent intellectual property rights of the mechanical transmission axis CNC milling machine equipment, a top priority.

In 2006, commissioned by the State of the Three Gorges Construction Committee, assumed the development of Jinan Machine Tool sets the first major task of the project. Them more to tackle technical problems, struggled, and finally a breakthrough. Less than a year Bianjiang products delivered to the user Angang Heavy Machinery Corporation. This set of products with advanced features five-axis cutting weight to complete the complex three-dimensional precision surface machining, the workpiece to be machined to improve the accuracy and surface finish, reduced or canceled after the order of hand-grinding, so as to solve both higher productivity but also improve the accuracy of problem cases to be processed to meet China’s Three Gorges Project, and major power generation, shipbuilding, military industry needs, free from dependence on foreign technology.

China Machinery Industry Federation Special Adviser to Mr. Lu recalled, this project started from May 2006, lasted three years, the effect was very good. Jinan two machines dare take on this difficult task, and Angang Heavy Machinery Co., Ltd. dare the first “eating crabs,” the success of the two key major projects.
Angang Heavy Machinery Co., Ltd. Chairman of Bi Zhi-chao, the machine tool over the past year, more than the past performance of the complete machine tools of all leaves, leaf water processing to break the bottleneck for the development of hydropower in China, played an important role.

Dongfang Electrical Machinery Co., Ltd. Deputy General Manager Zhang Tiande said mechanical CNC milling head, torque, low speed, high technical content, is a very big step forward. He believes it to China hydropower manufacturing industry, ship industry, as well as the construction of national defense industry, will play an important role.
China Machinery Industry Federation Special Adviser to Mr. Lu, the State Council Three Gorges Construction Committee Office of the technology and equipment, Ling Huang, deputy director of China Machinery Industry Federation, Director of Li Dongru technology work as well as from research institutes, and electricity, heavy machinery and other key industry experts, users, a total of more than 80 people attended the demonstrations.
