subject: China Cnc Tool And Instrument Technology Status And Development [print this page] "Eleventh Five-Year" period, China's manufacturing development of major projects of national priorities included energy, automotive, aerospace and transportation and other important areas related to people's livelihood, with their major Equipment manufacturing Involved in the typical characteristics of the key components are: a large, heavy, complex, sophisticated and difficult process in which new materials (such as aluminum alloy, titanium alloy, high strength heat-resistant steel, carbon fiber and composite materials, etc.) cutting accounted for a large proportion. This is a CNC cutting technology and CNC cutting machine equipped with new issues raised, and also NC Tool And digital measurement technology and Measuring Meter put new demands and challenges, providing new opportunities and arenas. Current development of CNC tool and equipment behind CNC machine tools Development, has become an obstacle to our CNC cutting technology and CNC cutting machine development bottleneck, change the status quo without delay.
To clearer understanding of the real CNC machine tools and measuring instruments used in machinery and equipment industry in China's major needs and application status, in particular, to further clarify the key components in the process of cutting, CNC cutting tools and measuring instruments made Status of foreign advanced technology and products with the gap in order to contribute to an objective, scientific confirmation: in the "Eleventh Five-Year" period and for some time, our tool industry in the CNC tool and digital Measuring instruments In the field of research directions and objectives, in June 2008, the author was privileged to participate by the China Machine Tool Industry Association organized on Nuclear power Wind power equipment manufacturing industry and the manufacturing part of the company's research tools, cutting tools and measuring instruments in China CNC machinery and equipment industry in the country's important status and development in a deeper feeling.
A nuclear power wind power equipment manufacturing in CNC tool and Application of Digital Meter
Energy equipment manufacturing industry, especially clean energy such as nuclear power, wind power equipment manufacturing industry developed rapidly in recent years. Power generation equipment such as key parts of some typical turbine blade, rotor and rotor-slot embedded groove cutting, etc., as are processed materials are heat-resistant high-strength alloy steel, stainless and other difficult materials, cutting large , cutting heavy load on the CNC cutting tools, such as high red hardness, bending and shear strength, abrasion resistance, adhesion, friction coefficient has a high demand. At the same time, high precision and complex surface of the cutting tool itself on the accuracy of NC also put forward higher requirements. Therefore, these power generation equipment typical part of the processing and testing, to a certain degree, and reflects the advanced technology and advanced numerical control cutting tool, advanced digital measurement technology and measurement results and the level of the latest equipment, much tool manufacturing industry concerns. In addition, the survey saw the high-precision, large-sized wind power transmission box gear forming growth rate and measurement, and the hard drive screw cutting roll forming and other new technologies have left a deep impression on people.
1. Turbine Blade CNC Machining
Today, the turbine blade axis CNC machining technology has been widely used. Turbine blades in large quantities, specifications, and outline the shape of complex, high precision and difficult process. And a heat-resistant, high strength, corrosion resistance, high-performance steel workpiece material adds to the difficulty of cutting, so the blade CNC tool indexable base material and coating performance requirements high. At present, the factory process is still used in most foreign carbide coated tool / blade. Learned in the research, the overall impact of turbine impeller forging processing have yet to research. On the turbine blades in the accuracy of detection, usually CMM For point level measurement, such as the use of PC-DMISBLADE software CMM on Measurement and analysis of leaf parameters; or light gaps at the scene were detected with a model, but the latter lack of quantitative determination. Enterprises expect the market to facilitate the application of production site, capable of rapid precision measurement of mass leaves the digital equipment.
