Recently, the 2023 Shanghai International Machine Tool Exhibition was held in Shanghai, and the booth of Junang Precision Equipment Co., Ltd. from Dongcheng, Dongguan attracted many exhibitors and visitors from home and abroad to stop and visit and negotiate. It is reported that the P-ONE (Optical Curve Projection Grinding Machine) developed by the company after ten years of research and development has won the favor of many exhibitors at the exhibition.

It is understood that the optical curve projection grinder is a high-precision mechanical processing technology. Using a plotter for processing, the plotter depicts the required graphics on the film, which is then attached to the projection screen and calibrated. The processor will perform the forming process based on the shape on the film. Suitable for forming and grinding high hardness materials, such as workpieces made of tungsten steel or hard alloys, and occasionally processing high-speed steel workpieces. The general processing of connector stamping dies involves the use of cutting edges and punches, terminals, precision half stroke punches, lower die inserts, and removal plate inserts, among other workpieces.

At present, PG optical projection grinding machines on the domestic market are mainly imported from Japan and require approval from the Japanese government before they can be imported into China. However, most PG optical projection grinding machines imported from Japan are small and general-purpose civilian machine tools that are only suitable for producing products such as automobiles and railways.

The PG optical projection grinding machine imported from abroad is also equipped with a global positioning device. The machine cannot move and cannot produce parts for military use. Before moving the machine, it must be declared to the manufacturer, otherwise the machine will be locked. ”Tang Dongsheng, Chairman of Dongguan Junang Precision Equipment Co., Ltd., said that their company has been engaged in research and development, production, and sales of optical curve grinders for many years. In order to solve the "bottleneck" problem of domestic optical curve grinders, the company began developing the latest optical curve projection grinder ten years ago. "Initially, we just wanted our own optical curve projection grinder to bring us closer to foreign products

In the research and development production, Tang Dongsheng leads the R&D team to summarize experience, innovate and increase efficiency, continuously polish equipment products, and ensure the high quality and performance of each device. Now, the optical curve projection grinder they develop and produce is the fifth generation product, achieving high-precision machining error of+-0.002MM. The control system and functions, projection magnification, focal length, and machining size accuracy can all reach the level of similar foreign machine tools. "We have made simpler and more convenient improvements through practical operation, which are even more intelligent than foreign machine tools and comparable to the 'Rolls Royce' in the high-precision grinding industry of the same kind." Tang Dongsheng said that when developing new products, we encounter many difficulties, and many core components can only rely on independent research and development.

After unremitting efforts by the team, the equipment has finally been successfully developed and put into use. Tang Dongsheng said that this technology will help the industrial development of precision molds, fixtures, cutting tools, electronic technology, military industry, and aerospace in China.

At the 2023 Shanghai International Machine Tool Show, a merchant from Zhejiang immediately signed an order after learning about the optical curve projection grinder at the booth of Dongguan Junang Precision Equipment Co., Ltd. More exhibitors and visitors requested relevant information. Currently, representatives from multiple companies have visited the company for inspection and signed letters of intent to purchase equipment.

By participating in this exhibition, we can intuitively understand the current development status of the same industry, exchange and learn from industry experts, and learn from each other. This not only expands the market, but also points out the direction for enterprise development. "Tang Dongsheng said that as a high-tech enterprise specializing in the research and development, design, production, and sales of optical curve projection grinders, the company will be committed to the core manufacturing and technological breakthroughs of optical curve projection grinders, actively carry out innovative exploration, and accumulate momentum for the high-quality development of Dongguan's economy, and establish the brand of" Dongguan Intelligent Manufacturing ". At the same time, we hope that relevant government departments can further build a "heart bridge" between enterprise supply and demand, and provide more policy incentives to enable enterprises to focus on research and innovation.
