Shanghai machine tool products have broken through technical bottlenecks

At the China International Industry Fair in 2013 (the fifteenth session), Shanghai Machine Tool Works Co., Ltd. exhibited a total of 5 new products on behalf of the Shanghai Electric Machine Tool Industry – the national major special project project product SK7420×2000 CNC screw grinding machine and SK7620/F CNC internal thread grinding machine, 2MK97300/H numerical control vertical internal and external cylindrical grinding machine, SHP-3025 CNC rotary head punching machine and CK6185(III)×3500 CNC horizontal lathe of Shanghai Heavy Machine Tool Works Co., Ltd. These products are characterized by technological leadership and high-end precision, and showcase a series of new achievements made by Shangji Company in the process of product transformation and upgrading in recent years. The exhibiting products have attracted the attention of many manufacturers.

SK7420×2000 CNC screw grinder and SK7620/F CNC internal thread grinder are the national “high-end bed and basic manufacturing equipment” technology special project “Supreme” undertaken by Shangji Company and cooperated with Shanghai Jiaotong University, Shanghai University of Technology and Shanghai University. The result of the precision ball screw and nut complete grinding equipment. Its research and development has successfully broken through the technical bottlenecks in the design, manufacture, grinding process and online quality inspection of China's high-precision ball screw and nut grinder, making its overall technical performance index internationally advanced and capable of domestic high-end. The precision manufacturing of the key components of the ball screw provides technical equipment. The main innovations of the results of these two projects include the stiffness matching technology of linear motors and mechanical components, the grinding flutter control method based on the analysis of machine tool dynamics, the detection and automatic compensation technology of ball screw transmission error, based on sound. Four aspects of the ball screw/nut grinding condition monitoring technology that is launched. Based on the R&D and manufacturing of the "High-precision Ball Screw and Nut Complete Grinding Equipment" project, the company will form a test and test base, R&D production base and customer base for high-precision ball screw and nut complete grinding equipment. Forming an application demonstration base, China's high-precision ball screw and nut grinding machine has reached the international advanced level in research and development and manufacturing, and laid a solid foundation for industrialization of product application as soon as possible.

Another product exhibited by Shangji Company 2MK97300/H CNC vertical internal and external cylindrical grinding machine is the only CNC vertical internal and external cylindrical grinding machine with the largest specification and the heaviest load in China. It can complete the parts by one clamping. The composite grinding of inner circle, outer circle, end face and cone surface, the overall technology of the machine tool is at the international advanced level. The machine tool has many visitors during the exhibition. At the same time, the machine tool has won praises from the exhibition review experts as the award-winning products, and was awarded the silver prize product of this exhibition.
