Editor's Note: In the aspect of numerical control system, multi-axis multi-channel and bus-type high-end numerical control device prototypes have been developed, and independent intellectual property rights have been formed in core technologies such as multi-axis linkage interpolation algorithm and error compensation. At present, the special technical process of “high-end CNC machine tools and basic manufacturing equipment†has made a major breakthrough.
Through the implementation of the special "Eleventh Five-Year Plan", "high-end CNC machine tools and basic manufacturing equipment" have broken through a number of key technologies such as high-speed and high-precision motion control and reliability design, and have developed more than ten kinds of internationally advanced Heavy equipment has played a positive role in the equipment manufacturing industry in response to the financial crisis. It can meet some of the needs of the four major fields, such as aerospace, and has completed the research objectives of the special "Eleventh Five-Year Plan".
The world's largest 36,000 tons of ferrous metal vertical extruder has been put into production a few days ago, solving a number of key technologies such as transmission and control operating system design and manufacturing, and achieved a major breakthrough in extrusion technology.
The successful development of this equipment has enabled foreign companies to reduce the price of large-diameter thick-walled steel pipes from 180,000 yuan/ton to more than 50,000 yuan/ton. It is estimated that the annual cost savings for related enterprises using the above products in China will be more than 10 billion yuan.
The 10-meter CNC bridge gantry turning and milling combined machining machine for large nuclear power unit turbine casing and other key parts processing masters the key technologies of three-section beam assembly and processing technology to ensure the machining accuracy of the machine tool. Two machine tools are delivered to the user. The ultra-heavy horizontal boring lathe with a diameter of 5 meters and a load of 500 tons has broken through the core technologies such as ultra-high-precision high-precision hydrostatic spindle technology. The main technical performance indicators of the machine tool have reached the international advanced level and have been delivered to users for use. Processing of a 1.1 million kilowatt supercritical nuclear power half speed rotor.
The key deployment of high-end CNC machine tools with large import volume and wide market demand has been carried out. Through the joint development of machine tool backbone enterprises, universities and users, research on key technologies such as structural optimization design and thermal compensation has been carried out. Ningjiang Machine Tool, Beijing Gongyan Seiki and other units have completed the development of more than 30 types of precision, high-speed vertical horizontal machining centers, CNC lathes, five-axis linkage machining centers and other new products, precision and speed can reach "11 At the end of the five-year international advanced level, the MTBF of the mainframe reached 900 hours. With the new products gradually put into the market, the technical level of domestic high-end CNC machine tools will be effectively improved, and the supporting verification of domestic high-end CNC systems and functional components will be promoted.
In the aspect of numerical control system, multi-axis multi-channel and bus-type high-end numerical control device prototypes have been developed, and independent intellectual property rights have been formed in core technologies such as multi-axis linkage interpolation algorithm and error compensation.
At present, Huazhong CNC, Guangzhou CNC and other units have completed the production of 50 sets of open all-digital high-end numerical control device prototypes, and related supporting verification work is underway.
In the implementation process, the special project actively creates a research environment in which common technologies and mainframes and components support each other, and requires higher education institutions and research institutes that undertake common technical issues to integrate superior resources to help enterprises solve practical problems in production and R&D. In terms of reliability technology research, Jilin University has developed a number of CNC machine tool reliability technical specifications, developed a reliability test and test bench, and provided reference for product reliability design and testing of key enterprises such as Shenyang Machine Tool and Dalian Machine Tool. .

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
