Recently, the 2023 Shanghai International Machine Tool Exhibition was held in Shanghai. The booth of Jun 'ang Precision Equipment Co., Ltd. from Dongcheng District, Dongguan, attracted many domestic and foreign exhibitors and visitors to stop by for viewing and negotiation. It is understood that the company's P-ONE (optical curve projection grinding machine), which has been developed for ten years, made its debut at the exhibition and was favored by many exhibitors.
It is understood that the optical curve projection grinding machine is a highly precise mechanical processing technology. With the aid of a plotter for processing, the plotter sketches the required graphics onto the film. The film is then attached to the projection screen and corrected. The processor will carry out the forming processing based on the shape on the film. It is suitable for forming and grinding high-hardness materials, such as tungsten steel parts or hard alloy workpieces, and occasionally some high-speed steel workpieces are also processed. Generally, it is used for processing parts such as cutting edges and punches for connector dies, terminals, precision semi-stroke punches, lower die inserts and release plate inserts, etc.
At present, the PG optical projection grinding machines in the domestic market are mainly imported from Japan, and they need to be approved by the Japanese government before being imported into China. However, most of the PG optical projection grinding machines imported from Japan are small and general-purpose civilian machines, which are only suitable for the production of automobiles, railways and other products.
The imported PG optical projection grinding machine from abroad is also equipped with a global positioning device. The machine cannot be moved and cannot produce parts for military industry. Before moving the machine, it must be reported to the manufacturer; otherwise, the machine will be locked. Tang Dongsheng, the chairman of Dongguan Jun 'ang Precision Equipment Co., LTD., said that their company has been engaged in the research and development, production and sales of optical curve grinding machines for many years. To solve the "bottleneck" problem of domestic optical curve grinding machines, the company began to develop the latest optical curve projection grinding machine ten years ago. "At first, we just wanted the optical curve projection grinding machines we produced to narrow the gap with foreign products." "
In the process of research and development and production, Tang Dongsheng led the R&D team to summarize experiences, innovate and increase efficiency, constantly refine equipment products, and ensure the high quality and high performance of each piece of equipment. Now, the optical curve projection grinding machine they have developed and produced is the fifth-generation product, achieving high-precision processing errors of +-0.002MM, control system and functions, projection magnification, focal length The dimensional accuracy of processing can all reach the level of similar foreign machine tools. "We have made more concise and convenient improvements through practical operation. It is even more intelligent than foreign machine tools and is comparable to the 'Rolls-Royce' of similar high-precision grinding machines." Tang Dongsheng said that many difficulties were encountered when developing new products, and many core components could only rely on independent research and development.
After the team's unremitting efforts, the equipment was finally successfully developed and put into use. Tang Dongsheng said that this technology will contribute to the industrial development of China's precision molds, jigs, cutting tools, electronic technology, military industry, and aerospace.
At the 2023 Shanghai International Machine Tool Exhibition, a merchant from Zhejiang Province, after learning about the optical curve projection grinding machine at the booth of Dongguan Jun 'ang Precision Equipment Co., LTD., immediately signed an order. More exhibitors and visitors also requested relevant materials. Currently, representatives from several enterprises have visited the company for inspection and signed equipment purchase intention letters.
By participating in this exhibition, we can have a direct understanding of the current development status of the same industry, exchange and learn from industry experts, and draw on each other's experiences. This not only expands the market but also points out the direction for the development of our enterprise. Tang Dongsheng stated that as a high-tech enterprise specializing in the research and development, design, production and sales of optical curve projection grinding machines, the company will be committed to the core manufacturing and technological breakthroughs of optical curve projection grinding machines, actively carry out innovative exploration, accumulate energy for the high-quality development of Dongguan's economy, and enhance the brand of "Dongguan Intelligent Manufacturing". Meanwhile, it is hoped that the relevant government departments will further build a "bridge of connection" between supply and demand for enterprises and offer more policy preferences, enabling enterprises to focus on research and development and innovation.
