Major progress and breakthroughs have been made in high-end CNC machine tools and basic manufacturing equipment

as an important part of the national major science and technology project of "high-end CNC machine tools and basic manufacturing equipment", two special topics, namely, die forging technology for large-scale key parts and material smelting and molding control technology for large-scale high-quality castings, have made major progress and breakthroughs recently. Analysts believe that in the long run, China's machine tool manufacturing industry may benefit. As a high-end numerical control machine tool and basic manufacturing equipment, the pressure shear experimental machine is mainly used for shear elastic modulus, friction coefficient and allowable rotation experiments. It has the following characteristics Oil cylinder type, 4-column structure, high rigidity, low strength and small deformation of the frame, which meets the experimental requirements of highway and railway bridge slabs, tanks and ball bearings. The experimental space is stepless and adjustable, which is convenient for the experimental requirements of different heights At present, there are many kinds of pressure shear experimental machines on the market. Two special topics, namely, die forging technology of large key parts and material smelting and molding control technology of large high-quality castings, have made significant progress and breakthroughs. Analysts believe that in the long run, China's machine tool manufacturing industry may benefit

research on the processing technology of globoidal cam and the temperature fluctuation of globoidal cam five axis machining center and globoidal cam six axis grinding center should not be greater than 2 ℃/h; Minjia company led the R & D and implementation of Xi'an Jiaotong University

recently, it was learned from relevant parties that as the executive vice president of Guangzhou Machine Tool Industry Association, Guangzhou Minjia Manufacturing Technology Co., Ltd. made a major breakthrough in the special CNC grinding machine industry in 2012: Minjia, as a unit for the first time, undertook the major special projects of national high-end CNC machine tools and basic equipment: Research on the processing technology of globoidal cam and the actual transaction price of five axes of globoidal cam is slightly lower than the market quotation processing center Six axis grinding center of globoidal cam. The goal of the project is to study the machining process of globoidal cam of tool changer mechanism of tool magazine, develop special equipment for manufacturing globoidal cam with independent intellectual property rights, meet the needs of functional component enterprises, and improve the design and manufacturing level of domestic tool magazine

at present, the mainstream configuration of the tool magazine of the machining center is the disc tool magazine with manipulator exchange. The globoidal cam is the core component of the disc tool magazine, and the manufacturing cost is more than half of the cost of the whole tool magazine. Solving the problem of globoidal cam manufacturing is equivalent to solving the manufacturing problem of the disc tool magazine with manipulator exchange tools, occupying a place in the market. Establish globoidal cam CNC machine tools and globoidal cam demonstration bases to fill the gap in domestic globoidal cam grinding technology
