Of mechanical analysis of developing processing center Processing center was originally evolved from the CNC milling first processing center in 1958 by the American Kearney Te Leike pany first successfully horizontal boring and milling it on the basis of an increase of automatic tool in order to achieve a clamping of the workpiece can be carried out after milling, drilling, boring, reaming and tapping a variety of processes such as centralized processing. The twentieth century, 70 years, the rapid development of processing centers, there may be processing center for the spindle box, it automatically replaced with a number of multiaxis spindle box with tools, the workpiece can be processed simultaneously manufacturing technology is the study of product design, production, processing, manufacturing, selling and use, maintenance services and even the whole process of recycling the engineering disciplines, is to enhance quality, efficiency, petitiveness as the goal, including material flow, information flow and energy flowplete system works March 2020 held in Shanghai, China CNC Machine Tool Exhibition, displayed more than domestic production of fiveaxis machining the Second Machine Tool Group Corporation, Jinan exhibited fiveaxis gantry machining center, table length 6m, width 2m, with vertical spindle, Aaxis rotation 177。 100 176。, Caxis 177。 200 degrees angle, this monster has attracted manyvisitors, it marks China39。s CNC machine tool industry has reached advanced Machine Tool Plant, the third, fourth machine tool manufacturing plant vertical and horizontal machining centers, table 630mm, highspeed internal cooling spindle, spindle can be set, lying conversion table with 360 degree attainment, similar to the simple configuration for the legislature, horizontal axis conversion processing center, the workpiece can be processed to achieve fivesided, although not configured axis, is also very practical. 哈爾濱工業(yè)大學(xué)華德應(yīng)用技術(shù)學(xué)院畢業(yè)論文 29 Processing center now has bee the most important mechanical processing equipment, a wide range of its processing and high recent years, variety, performance, features having a significant : the new legislation, fiveaxis horizontal machining center, can be used for aviation, aerospace parts machining。 are dedicated to highperformance mold processing center, integrated threedimensional CAD / CAM of plex surfaces super finishing die。 that applyin the automotive, motorcycle parts processing large quantities of highspeed machining centers, high efficiency and have the : the widespread adoption of more than turn spindle million, up 6 to 10 million transfer。 The application of linear motor machine tool acceleration of the 35g。 the implementation of ISO / VDI testing standards, prompting manufacturers to improve the processing center : blend of laser processing of plex functions, structural ponents for modular manufacturing cell (FMC) and the flexible production line (FMS), and has the mechanical and electrical, munications integration capabilities. 2. The characteristics of machining centers Process focus Machining Center with Tool and can automatically change tools, multiprocess machining the workpiece, so the workpiece in a fixture, the numerical control system can control the machine by different processes, automatic selection and replacement of tools, automatically change the spindle speed, feedvolume and trajectory of the tool relative to the workpiece, and other auxiliary functions, modern processing center to a greater extent after clamping the workpiece in a multisurface, multifeature, multisite continuous, efficient, highprecision processing, the process is the most prominent feature of machining centers. The adaptive processing object Production of flexible machining centers not only in rapid response to special requirements can rap
