It is understood that at present, China needs to import more than 300 optical contour grinders and various multi-function precision surface grinders each year, each selling for hundreds of thousands of dollars. To this end, domestic machine tool enterprises to improve grinding machine research and development technology, breaking the international technology blockade has become a critical task. Under the development of economic recovery and the support of national policies, China's grinding machine enterprises have carried out structural adjustment and industrial upgrading, and further developed new grinding machines and new grinding technology, and achieved significant results in grinding machine research and development projects. Hangzhou Machine Tool successfully developed the MKB7025 CNC track plate special grinding machine developed by Hangzhou Machine Tool Group Co., Ltd., which is one of the high-speed railway construction heroes. The first set of track plate grinders has created an unprecedented speed record for new product development from design, manufacture to installation and commissioning. It has been praised by the society as “high-speed railway speed” for the development of high-speed rail construction and innovative track plate grinding machines. The track plate grinding machine developed by Hangji Group has continuously improved its production efficiency and created a good record for processing 120 track plates every day. In the process of developing track plate grinding machines, Hangji attaches great importance to technological independent innovation on the basis of digesting and absorbing advanced technology, and has achieved many innovative technological achievements. This series of products has won the patent technology granted by three national patent offices: the gantry frame type overall moving mode "beam moving CNC grinding machine", the grinding head rotary shaft high torque locking mechanism "machine tool slewing mechanism hydraulic disc lock “Device”, “large-scale workpiece hydraulic support leveling clamping device” for advanced 9-ton heavy-duty workpieces with advanced hydraulic automatic load-bearing, automatic leveling and stress-free clamping technology. These 14 track-plate grinders have increased the sales revenue of Hangji over 100 million yuan, and also broke the technical barriers and blockades of high-speed railway construction in developed countries, which has achieved high social benefits for Hangji. Shanghai Machine Tool Plant has developed a new generation of high-efficiency precision cylindrical grinding machines . Based on the research and development achievements of the past few years, this year, the company successfully launched a new generation of high-efficiency precision cylindrical grinding machines. The machine has a maximum turning diameter of 500mm, a maximum workpiece length of 3000mm and a maximum workpiece weight of 1000kg. The machine tool adopts the company's newly developed high-efficiency and high-precision dynamic and static pressure bearing, and adopts the bearing support structure with independent intellectual property rights. On the basis of fully guaranteeing the high-precision, high-speed and uniform slewing support of the spindle, the grinding of the large cutting amount is realized. The grinding efficiency is more than three times that of the original model. On the basis of the breakthrough of high-efficiency grinding technology, the product can realize rough grinding and super-fine grinding with the same type of grinding wheel without replacing the grinding wheel. The grinding rate is high and the grinding wheel loss is reduced, and the higher grinding amount can be obtained under the same motor power condition. These research and development results are the first application in China, achieving high-efficiency and high-precision grinding in the true sense, which has raised the development of the overall technology of the grinding machine to a higher stage, while greatly reducing energy consumption and quality stability. This new product can be promoted and applied as an exemplary model of advanced manufacturing technology. Technological innovation, quality improvement, and perfect marketing and service mechanisms have injected new vitality into the brand-name strategic activities of Shangji Company. It not only enhances the overall strength of the company, but also creates value-added potential for its customers. The quantity tool introduces the SK723 CNC Taper Thread Grinder Mass Tool Group Co., Ltd. The tool special machine tool introduced by CIMES2010 - SK723 CNC tap thread grinding machine is used for the processing of tap thread. The grinding machine is used for grinding the workpiece with diamond. The automatic grinding device of the roller selects the high-precision CNC closed-loop control system, which is convenient for operation and programming. Due to the use of finite element analysis software to optimize the design of the machine structure, the overall rigidity is improved. The grinding wheel spindle of the machine tool is a high-precision special grinding spindle. The motor is a stepless adjustment variable frequency motor, which can realize the constant speed operation of the grinding wheel line speed. The wear compensation of the grinding wheel for various workpiece machining is realized by 4 CNC axis linkage. Each feed axis is realized by a servo motor driving a high-precision screw rod pair. The machine tool is equipped with a fully enclosed outer cover and a dust suction device, which can process straight grooves, spiral groove taps, extrusion taps and the like. For the mass production of taps, the dressing device with a shaped diamond roller is directly trimmed to greatly shorten the dressing time. The CNC system of Taiwan Baoyuan is used for easy operation. It is equipped with the servo motor and its driver of Yaskawa, Japan. The working and grinding heads are equipped with high-resolution grating scales to realize closed-loop control, which can automatically compensate the wear amount of the grinding wheel during the processing and trimming process, and improve the processing precision and efficiency of the product. . Sanming Machine Tool CNC Precision Grinder breaks the international technical blockade situation. Fujian Sanming Machine Tool Co., Ltd. (hereinafter referred to as Sanming Machine Tool) and Xiamen University jointly undertake the “Eleventh Five-Year” major special project of Fujian Province, “Advanced Machinery Equipment and Key Technology Development The major topic in the "Applications" "four-axis CNC precision grinding machine and the development and application of key technologies" passed the acceptance of the expert group of the Science and Technology Department of Fujian Province. The project has produced the first four-axis CNC precision grinding machine in China, which can be used for precision machining of hard and brittle materials such as ceramics and glass products, and the processing precision has been improved from the original 1 micron to 0.1 micron, reaching a hair diameter of about one hair. At the level of one thousandth, this technology has filled the domestic gap and broke the international technological blockade. At the beginning of June this year, the precision grinding machine was sent to a certain unit in Chengdu by Sanming Machine Tool and officially applied to production. The successful development of precision four-axis CNC machine tools and corresponding measuring methods can break the foreign blockade of China's introduction of high-tech and its equipment, and realize the localization of high-precision ceramic products and photoelectric components, with significant social benefits. The achievement of these achievements shows that China's grinding machine enterprises continue to innovate and develop, and deepen the research and development of high-quality, sophisticated and sophisticated products, strengthen the structure of production, learning and research, strengthen the introduction and cooperation of technology, and further improve the degree of informationization of enterprises. The domestic position of domestic grinding machines.
