Equipment of large numerical control finishs high-grade science and technology tackles key problem

4.2 billion yuan, its China dials funds 1.

2.4 billion yuan, arranged difficulty of 20 kinds of technologies early or late price of big, entrance very tall or the high-grade that abroad limits an import to our country is large the development of numerical control equipment; Supported a batch intermediate numerical control machine tool and the research that numerical control system produces the industrialization of base to prop up a technology; The research that began the crucial function component such as main shaft of numerical control system and servo drive technology, high speed to consider to wait for technology of general character of a batch of foundations. Current, this batch of science and technology tackle key problem the project already obtained level sex positive result, the research of a few crucial technologies obtains a breakthrough, research and development gives a batch of high-grade equipment of large numerical control, research of technology of fundamental general character and application also obtained result. 20 kinds of high-grade are large numerical control equipment is major already 20 kinds of high-grade that emphasis of consign use nation arranges are large the science and technology of numerical control equipment tackles key problem already finished, at present major already consign is used. 5 axes linkage mixes the dragon door type that if Qi Qi breaths out Er,university of factory of the 2nd machine tool, Tsinghua and factory of Harbin electric machinery develop development jointly online bed, basically use at machining the curved surface spare parts such as lamina of large hydraulic turbine; Door of 5 axes dragon machines the high speed that factory of the 2nd machine tool and graduate student of Beijing aerospace college produce Jinan machine tool, basically use at treatment " south water north is moved " the lamina of large water pump of the project; Joint-stock company of hi-tech of Beijing Electromechanical courtyard is Oriental turbine the machining center of lamina of 5 axes linkage that the factory develops can satisfy 600MW turbine the treatment quality of large lamina and treatment efficiency requirement, the price is an entrance only 1/3 of congener machine tool. The mill of much axis car that Shenyang machine tool develops is compound machining center, basically use at pump housing, essence osculant plug-in unit, insert fast commutator and spiral ribbon close outfit, the treatment of the complex form spare parts such as broach of diamond tooth gear, suit the development of product of new technology of national defence industry particularly. The large CNC Turning that develops development independently by limited company of machine tool of Nanjing numerical control processes unit, have torque big, rigid good, precision is overall and tall, dynamic character is good wait for a characteristic, it is the equipment that machines spare parts of large water pump to be badly in need of. The boring machine of mill of numerical control of type of 5 axes be born that development of joint-stock company of machine tool of numerical control of Jiangsu much arris develops, basically use Yu Dazhong diesel engine, large and medium-sized treatment of complex structural member, special apply to the complex part high speed that has dimensional curved surface, efficient treatment.
