The "863 Program" national initiative, led by Wuhan Heavy-duty Machine Tool Co., Ltd., has successfully completed its development phase with the creation of a heavy-duty vertical seven-axis five-link motor-milling compound processing machine tool. This groundbreaking project has recently passed national acceptance, and the expert evaluation panel has recognized it as the first domestically developed composite machining system with independent intellectual property in China.
After three years of collaborative research and development between industry, academia, and technology institutions, the prototype machine has been successfully completed. It features a maximum turning diameter of 8,000 mm, a height of 2,000 mm, and can handle workpieces weighing up to 100 tons. In addition to high-precision milling operations, the machine is capable of cutting the blade surfaces of propellers. By combining turning and milling technologies, it enables the simultaneous machining of multiple surfaces of a propeller, ensuring both the dimensional accuracy of the profile and the positional precision of each machined surface—significantly improving the overall quality of propeller manufacturing.
The project was jointly undertaken by Wu Zhong, the National CNC System Engineering Technology Research Center at Huazhong University of Science and Technology, and Zhenjiang Ship Propeller Factory. The technical appraisal and product acceptance were conducted by an expert group commissioned by the Office of Advanced Manufacturing and Automation Technology under the National 863 Program. This achievement marks a major milestone in China's efforts to advance high-end manufacturing and self-reliance in critical industrial equipment.
Socket Wrench Tool Set
Introduction to socket wrench tool set
The automotive repair socket wrench tool set is a professional manual tool combination designed specifically for vehicle maintenance, upkeep, and disassembly. It usually includes various accessories such as sockets, wrenches, extension rods, universal joints, ratchet handles, etc. It can handle bolts and nuts of different sizes and is suitable for maintenance operations on engines, tires, chassis, and other parts.
