In order to promote international exchanges and cooperation in high-technology equipment, non-standard parts processing build China's equipment manufacturing industry innovation and development platform, "2013 China (Nanjing) International Metalworking Exhibition (AMB China)" will be held October 14 - 16 May held in Nanjing.

Current international metalworking exhibition jointly organized by the Jiangsu Provincial Economic and Information Technology Commission and is located in the world's top metal equipment manufacturing base in Stuttgart, Germany International Exhibition Company, Jiangsu Province Machinery Industry Association and the Stuttgart Exhibition Co., Ltd. Nanjing and co. Strong global high-end equipment area Baden - Wurttemberg end machine tools, machinery manufacturing joint German Chamber of Commerce, the European Machine Tool Dealers Association, the International Society for Production Engineering and Switzerland, Japan, Italy, Austria and other countries and regions, precision tools and intelligent equipment dealer to exhibit. China Machinery Industry Federation, China Mechanical Engineering Association, China Renewable Energy Society, Chinese Society of Automobile Manufacturers cum Jiangsu Machinery Industry Association, Jiangsu Province Machine Tool Association, Nanjing Automation and Instrumentation Association and other industry departments will organize separately owned enterprises a wide range of exhibitors.
The exhibition hall set up a special body involved in the equipment manufacturing industry innovation and development of core technology and industrial upgrading of industrial automation processing equipment, gear manufacturing technology, high-end equipment and its flagship chain equipment, which provide live demonstrations for users and equipment manufacturers and the best platform for trade exchanges. Non-standard parts processing this exhibit shows covering the entire field of metal processing, including metal-cutting machine tools, metal forming machine tools, used and reconditioned machine tools, precision tool parts, machine tool accessories and measuring systems, quality control systems, automation and motion control systems, mold manufacturing and other areas. Many international elite technical equipment and well-known domestic enterprises will be hundreds of new products, new technologies full debut exhibition. Chairman of Jiangsu Province Machine Tool Association, chairman of the Group of Jiangsu Yang Lin Guofu said the eight cities in economically developed Jiangsu Province along the Yangtze River has become CNC machine tools and mechatronics manufacturing, electronic and communication equipment manufacturing, shipbuilding and automobile manufacturing, internal combustion engines and Outbound high product manufacturing accessories, power transmission equipment and electrical machinery manufacturing in the country to drive and influence a large industrial zone. Nanjing International Metalworking annual exhibition is to show China and the world, one of the main front and contemporary metal processing equipment manufacturing level. Equipment manufacturing industry is currently supporting and leading a strong driving force of global economic development, and total exports of Jiangsu economy for many years, according to the country, thanks to the lead in the development of equipment manufacturing industry.
Detailed technical machining processes
Machining process required to arrange processing step, so as to ensure the quality and efficiency of machining parts. Arrange machining process mainly from the following aspects:
First, the first reference: processing machine parts and more generally from the fine reference processing starts again with reference positioning precision machining other surfaces. Therefore, choose to do the reference surface should be arranged in the first step of the process starting processing, in order to provide a reference for subsequent finishing processes. For example, the first shaft hole machining both ends of the center, and then to the center hole as a fine benchmark crude, finishing all outer surfaces. Non-standard parts processing gear machining process within the first hole and the reference end surface, and then within the hole and the end as a fine reference, rough and finish tooth surface.
Second, after the first crude refined: fine reference processing is completed, the entire part of the machining process, the first step should be rough, have a semi-finishing, finishing and finishing. After the first crude refined by the principle of high precision machining first major surface, which is to re-roughing semi-finishing of the main surface, and finally finishing and finishing. Before important surface finishing, and sometimes need to be trimmed fine reference, in order to facilitate the processing to ensure the accuracy of important surface, such as when high-precision grinding spindle, the former ultra-fine grinding and grinding are required to polishing center hole; precision gear before grinding teeth, but also internal grinding holes.
Third, after the first time the main: function and according to the technical requirements of the parts, the first part of the major surface and secondary surfaces are separated, and then processing in the first major surface, then the surface of the secondary processing step inserted therein. Minor surface generally refers to the surface of the keyway, holes, pin holes and the like. These surfaces are generally related to the main surface of a certain relative position requirements, should be the main surface as a secondary reference surface processing, so secondary processing surface ships on the main surface of the semi-finished later, before finishing, primary processing End. There are also placed at the end of processing, but you should be careful not to bruise the main surface has been processed.

Fourth, non-standard parts processing first surface of the hole: For housing, base, frame and other parts, the outline of the larger size of the plane, use it as a reference precision machined hole, more stable and reliable, but also easy to process, helping to ensure the hole accuracy. If the first hole machining, processing and then to the hole as a reference plane, is more difficult, processing quality is also affected.
