Computer Numerical Control (CNC) machining is an automated fabrication process in which computers control machine tools via programming inputs to manufacture various products or prototypes. It is the unique software and control console the machine uses that sets the system apart from other manufacturing techniques. Common machine tools used in conjunction with precision CNC machining include grinders, mills, lathes, and routers.

After thorough discussion, the members of the appraisal committee agreed that the main technical parameters and machine performance indicators of the two products can reach the leading level of international and domestic similar products. The TWB-700 hydraulic rotary table is the first in China, filling the domestic gap. The development of the two products was successful and could be put into mass production.
The appraisal committee highly praised the rapid development of Hengli Company under the leadership of Zhongqiu, the chairman of the reform, and believed that in just five years, Hengli’s product service target developed from traditional agricultural products to automobiles. In the engineering machinery, aviation, mold and other industries, the service market has expanded from domestic to Southeast Asia, Europe and America; the product series has developed from the low-end market (combined machine tools and general-purpose components) to the high-end market (processing centers and patented products), and the internal quality of enterprise management has been sublimation. The company has won the provincial private technology enterprise, the provincial AAA-level contract and trustworthy enterprise, the ISO9000 quality management system certification, the “credit Jiangsu integrity unitâ€, the Jiangsu market recognized brand-name product enterprise, the national machinery industry “1250†key engineering enterprise, the national advance Export businesses. At present, Hengli's products form two major technical platforms: machining center, combined machine tool and common parts, rotary milling machine, special machine tool, non-standard production line and equipment, steel cord production equipment, Cnc Machine tools, five major categories of products, 20 series, become a combination machine tool and special The production base of machine tools, in which the output of the leading product combination milling machine has been in the domestic market for more than 52 years, is in the forefront of the industry.
The TWB-700 hydraulic rotary table is jointly developed and produced by Yamazaki Technology Co., Ltd. of Japan. It adopts double wedge ring-steel ball positioning mechanism. When the indexing table is not lifted, the electrical and hydraulic adjustment mechanisms are located at the base joint surface. Upper part, easy to use and maintain. In operation, the annular guide surface is used as the main positioning surface, and the steel ball is placed on the four inclined surfaces of the inner and outer rings under the pressure plate for radial and circumferential positioning. The indexing time is 3-5s, the indexing accuracy is up to plus or minus 5, the repeat positioning accuracy is up to plus or minus 3, and the station book can be 2, 3, 4, 6, 8, 12, 16. The number of grooves can also be changed as needed. To achieve a special number of stations. The diameter of the table body can be increased according to special requirements, up to 40%, and does not affect its overall performance. The entire workbench is waterproof and can be used for large flow cooling applications. The design of the rotary table is advanced and reasonable, and it has been qualified by the State Intellectual Property Office for invention patents and utility model patents. It has high indexing precision, precision maintenance model, good rigidity, strong carrying capacity, convenient adjustment and maintenance, wide application range, and can be used in machine tools to complete boring, milling, drilling, expanding, reaming, tapping and other multi-process processing. The machine performance has reached the leading level of international similar products and is the first in China.
The precision spindle used in the VMC2000 CNC gantry milling and milling center is equipped with a two-speed ZF reducer that has a cold machine for high-speed and heavy-duty cutting. The Y-guide rail is 30-inclined, and the Z-axis uses a double-moment guide ram. The drive chain is short, and the machine tool adopts modular design. According to the user's needs, the tool magazine, various accessory milling heads, CNC rotary table, etc. can be configured to achieve high-efficiency precision machining.
It is understood that the company plans to invest 6% of annual sales to develop new products. Promote the upgrading of the company's products, win the differentiated market with the differentiation of handling, and improve the competitiveness of Hengli products in the high-end market.
TWB-700 hydraulic rotary table fills the domestic gap
The TWB-700 hydraulic rotary table and the VMC2000 CNC gantry milling and milling center developed by Jiangsu Hengli Combination Machine Tool Co., Ltd. (formerly Yancheng Hongqi Machine Tool Plant) successfully passed the Jiangsu New Product Production Appraisal Meeting and Technology on April 22, 2006. Results identification meeting. The appraisal meeting was jointly held by the Jiangsu Provincial Economic and Trade Commission and the Jiangsu Provincial Department of Science and Technology. Xu Wangquan, Vice President of Jiangsu Machinery Industry Federation, Fu Dongyu, Dean of Jiangsu Machinery Research Institute, Combined Machine Tool Branch of China Machine Tool Industry Association and Quality of Hydraulic Components Supervised testing centers, Dalian Combined Machine Tool Research Institute and some colleges and universities experts and scholars also attended the meeting.
