Jinshang 5-axis U-axis controlled machining center Pearl River Delta generator has become the company’s most popular cargo EDM The latest technology in forming is true micro-machining-comprehensive detection of the parameters of shaft parts in the laser micro-machining system. The new products of JUNKER grinding machines are unveiled at the design of CIMT 2007 special-shaped bottle cartoning machine and the accuracy analysis when electrically controlling shaft parts. Pay attention to the torque matching of the small module gear hob CAD system tool system market trends and technical development trends.

For more than ten years, the structure, drive and technical performance of high-speed machining centers have been greatly developed and improved. In the structure and driving mode, it has experienced the second generation development from ball screw-pillar moving type to linear motor-frame structure. Nowadays, high-speed machining centers are developing toward parallel-series hybrid kinematic structure to further improve the dynamic performance of machining centers. Currently, characterizing high-speed machining.

For more than ten years, the structure, drive and technical performance of high-speed machining centers have been greatly developed and improved. In the structure and driving mode, it has experienced the second generation development from ball screw-pillar moving type to linear motor-frame structure. Nowadays, high-speed machining centers are developing toward parallel-series hybrid kinematic structure to further improve the dynamic performance of machining centers. At present, the shaft acceleration characterizing the dynamic characteristics of the high-speed machining center has reached 1 to 2g, and the fast travel speed has reached 80 to 120m / min. This has created conditions for greatly reducing the auxiliary time. For example, when the shaft acceleration is 1.2g, the fast travel speed is 120m / min, and the shaft travel distance is 800mm, the shaft positioning time only takes about 0.5s. The application of high-speed cutting and high-speed feed makes the basic time of processing become shorter and shorter. For example: M6 screw holes with a milling depth of 14.1mm only need 1.2s, which shows that the modern high-speed machining center has successfully merged the originally contradictory flexibility and productivity.

Nowadays, due to the fierce market competition in the world’s auto industry, the speed of car replacement is obviously accelerated, and the product market life is further shortened. At the same time, the number of automobile variants has gradually increased, and the batches in production have been decreasing. In order to meet the different personalized needs of the global market, multi-variable flexible production has increasingly become the deciding factor of competition, and the production efficiency and flexibility of the equipment have become the main factors for selecting equipment. Before the 1980s, the rigid automatic line was the only highly efficient

Automation equipment. With the improvement of the reliability of the CNC system and the need for production of multiple varieties in the automotive industry. In the early 1980s, the flexible automatic line came out, and it has been widely used. However, the workpieces processed by the flexible automatic line are highly similar in geometry and processing technology, and these workpieces should be determined when the automatic line is designed. In addition, since all the processing stations of the flexible automatic line are in a complementary relationship, when a machine tool of the automatic line fails, it will cause the entire line to stop, resulting in a decrease in equipment utilization, even in the best case The utilization rate is only 70%.
