Fiber laser cutting is a technology for cutting metal materials. The Laser Cutting Machine uses high-power fiber optic lasers and is usually used on industrial production lines. Laser cutting systems for laser cutter allow cutting of any metals regardless of heat-conducting properties, with a thickness of 0.5 to 30 mm, and include IPG Photonics fiber-optic laser sources with power from 300 W to 15,000 watts. The fiber laser cutting machine is high efficient, good effect for metal cutting.

After the production and sales of automobiles have exceeded 18 million, the problem of the large but not strong Chinese auto industry has also been highlighted. Song Jian, a professor at the Department of Automotive Studies at Tsinghua University, pointed out that the biggest drawback of self-owned brands is the lack of core component technologies, because the functions of all cars are mainly based on the parts and components of automobiles. Therefore, breaking through the bottleneck of core parts is a common issue faced by their own branded car companies.
Beijing Motors, which started relatively late, made its first move in core component R&D. In September this year, on the basis of digestion and absorption of Saab's turbocharged engine technology, Beijing Auto's B205/235 series engine was rolled out. On December 25, Beijing Automobile Power F25/F35 transmission also announced full production. This means that Beiqi Power has been upgraded from absorbing Saab technology to an independent R&D production powertrain stage, and Beiqi's own brand autonomous powertrain module has taken shape.
Ma Tongli, general manager of Beijing Automotive Powertrain Co., Ltd., introduced the mass production of the F25/F35 manual transmission from the Weigel transmission line and technology, is a high-end high-torque manual transmission, product quality and performance have reached the original machine Level, some indicators even exceeded. Among them, the maximum torque of F25 is 250Nm, and the maximum torque of F35 is 350Nm.
According to statistics, Weigel is Saab's original supplier and has been supporting transmissions for the U.S. General Motors, with a production history of more than 50 years. After acquiring the engine platform technology of Saab in Sweden, in February 2011, BAIC Group acquired all the equipment and technical documents of the Weigel transmission plant, including the F25/35 transmission assembly production line and 22 self-manufactured parts production lines, as well as supporting quality. Control, maintenance trial production, power equipment, spare parts preparation, production technical data, product information and so on. Beiqi Power also became the first company in China to have transmission manufacturing capacity and complete intellectual property rights for high torque passenger vehicles.
Ma Tongli said that in order to ensure product quality, in the acquisition of technology, equipment, Beiqi Power also received up to six months of technical support and production training, in order to master the production of F25/F35 transmission key to provide protection. "The F25/F35 series products produced by Beijing Automotive Industry Co., Ltd. are produced in accordance with the original Saab F25/F35 transmission product standards. Not only the original suppliers are used as the spare parts, but also the equipment state and machining accuracy have reached the original factory. At the level, some of the indicators are even more stringent than the original."
