High-speed machining technology is produced in the dynamic and changeable market economy environment. In the fierce market competition, the company has high product quality, low cost, fast market, good service, clean environment, and timely product innovation, so the high-speed processing technology continues to develop. Since the 1980s, high-speed processing technology based on traditional metal (non-metal) processing technology, automatic control technology, information technology and modern management technology has gradually developed into an integrated system engineering technology. It has been widely used in the production process of manufacturing enterprises (such as modern automobile (automobile) vehicle production enterprises); the social demand for personalized products has increased, and under the conditions of multi-variety production, small batch production (in machinery manufacturing, this kind of production mode will account for 70% of the total output value), professional manufacturing high-speed processing technology will be further applied and developed in the production process of discrete or mixed enterprises (such as molds, energy equipment, ships, aerospace, etc. production enterprises). At the end of the 20th century, China reformed its planned economic system, reformed and opened up, and built a socialist market economy system with Chinese characteristics. The tools and practice of advanced CNC high-speed machining technology follow the introduction of automatic production lines, (tools), and CNC machine tools (equipment), which are widely used in the machinery manufacturing industry, and the corresponding management models, technologies and concepts will be integrated into the enterprise. Entrepreneurs have a profound understanding of the important position and role of modern information technology and enterprise system in future sustainable development and market competition. The socialist market economy environment should not only promote the transformation of enterprises, adjust the industrial structure and technological innovation, but also show the application and development of high-speed processing technology in professional manufacturing, which has broad prospects. 2, China's imported CNC automatic production line high-speed machining technology 2.2, FAW-Volkswagen engine drive (through) blank part 2.3 FAW-Volkswagen, through the production line of high-speed cutting tools, using super-hard tool materials for high-speed machine tools and processing tool materials. CBN, Sin, Ti, TiCN ceramic ceramic tool coating materials process high-strength cast iron with a milling speed of 2200m/min; through PCD, ultra-fine high-silicon-aluminum cast carbide milling cutter, the milling speed reaches 2200m/min, drilling, Reaming 80 ~ 240m/min speed; using silicon nitride ceramic, Ti ceramic and TiCN coating tools to process precision forging steel parts, rotating at a speed of 200 m/min; high cobalt powder metallurgy high speed steel TiCN coating for broaching the entire surface , special broach for hob, razor and carbide clamp combination, Processing all kinds of precision forged steel, cast iron, cutting speed 10 ~ 25m/min, hob speed 110m/min, shaving cutting speed 170m/min. The typical structure and part of the tool adopts the machining technology of composite material blade processing machine tool (blade machine clamp, welding structure, hinge, combination) instead of grinding and extrusion cutting, one-time hole processing during the cutting process, speeding up 3000r. 1.5 pm ~ cutting speed can reach 3 m/min, accuracy can reach 5 ~ 7, roughness ra0.7μm (gun drilling speed is 8000r. pm 2 m); some face milling cutter teeth, repeated positioning, clamping structure, high-speed teeth The diameter and axial direction of the face milling cutter are adjustable. 250 ~ 400mm diameter diameter, axial runout <+ 0.0025mm. Machining and assembling planes, milling instead of grinding, the roughness of ra0.7μm, the roughness is less than 0.02mm; the crankshaft and crankpin processing, using special tools for double-turn drawing and cutting. The cutter diameter is 700mm, professionally manufactures circles of 40-coated carbide inserts, each 10 pieces are in a group, the cutting speed is 150m/min, the fast forward speed is 4.6m/min, the cutting is 1.5 ~ 3mm / radial shift produces 350 pieces Allowance: The machining of the crankshaft main bearing cover adopts the side-mounted type, the special tool for the compound drawing machine. 3. Forming and installation, a total of 713 indexable coated carbide inserts (TiCN), and the feed speed is 25m/min. The shift produces 1750 pieces. Cutting allowance of broaching 1.5 ~ 3mm; round cylinder and cylinder head assembly crankshaft camshaft shaft and side surface, combined shaft series, three-blade special tool machine, professionally manufactured from 6 to 8 cutter set assembly, total ABO installation UT Star Kang 146 machine clip can index the coated blade, complete 10 square in radial cutting and milling, 1.5 ~ 2mm machining allowance; drive synchronous gear.
