Hefei Zhongtong Polishing Machinery Co., Ltd. was established by technical personnel from Anhui General Machinery Factory, which was formerly under the Ministry of Ordnance Industry. The company specializes in the design, manufacturing, sales, installation, and provision of process solutions for mechanical polishing (grinding) equipment. For over a decade since entering the polishing (grinding) machinery industry, we have been adhering to the professional spirit and attitude of the military industry, and have cooperated with professional institutions to develop and absorb foreign professional polishing (grinding) technologies. Guided by market demand, we have provided polishing (grinding) machinery (production lines) to more than a thousand domestic and foreign enterprises, including Baosteel, CRRC, CSIC, China National Nuclear Corporation, AVIC, PetroChina, Sinopec, CIMC, Sany Heavy Industry, Dongfeng Motor, Jianghuai Automobile, and Heli Forklift. The new generation of fully automatic CNC head polishing machine, jointly developed with Hefei University of Technology, Hefei General Machinery Research Institute, and the Third Design Institute of the Ministry of Chemical Industry, has achieved full head polishing. Process automation is widely used in the pharmaceutical machinery industry, food machinery industry Equipment industries such as water treatment equipment and chemical machinery. Based on professional technical research and talent, the company has accumulated rich practical experience in the research and product development of metal surface sand belt grinding and polishing processing technology, and has certain professional advantages in the domestic polishing industry, by integrating the technical advantages of high-quality grinding tools from international professional companies (3M from the United States, VSM from Germany, and Buffalo from Japan). The miniaturized head and tank polishing machine has been widely used in the pharmaceutical machinery, medicine, and water treatment equipment industries by companies such as Canaan Technology, Jinchao Technology, Shandong Jinying, and Harbin Nano. It is also widely used in water treatment equipment industries such as non negative pressure water supply, filter industry, and LNG cylinder industry. Large scale head and tank polishing machines are widely used in heavy machinery, such as nuclear power generation equipment, oil transportation pipelines, and welding seam polishing of large oil storage tanks in the chemical industry. Customers include China National Nuclear Corporation Qinshan Nuclear Power Station, Formosa Plastics Group, Liaoning Jinxi Chemical Machinery, Nanjing Chemical Machinery, and Taiji Enamel. Our large-scale flat polishing (grinding) machine is widely used for flat mirror polishing (grinding) of composite stainless steel plates, stainless steel plates, aluminum plates, and titanium plates. Our self-developed heavy-duty wide width sand belt grinder has been directly used by customers to replace gantry milling machines for processing large flat plates, fully reflecting its high efficiency and high-quality surface effects. It has been adopted by Second Automobile Group, Jiangnan Chemical Industry, Northern Industry Company, and Jingxiu Group We have developed and produced a production line for grinding (polishing) the curved and end surfaces of radiators for users in the radiator industry. A single shift can save 29 workers, with an efficiency 80 times higher than manual grinding. The centralized dust removal improves the environment, significantly reduces costs, and greatly improves surface quality. Therefore, it is widely adopted in the cast iron (aluminum) radiator industry and has obtained national invention patents. We have developed and produced a rotary multi station polishing machine for the cast iron and stainless steel pot industries, filling a domestic gap with an efficiency 20-30 times higher than manual labor. The fork grinder we developed and produced for Heli Forklift Co., Ltd. is not only widely used in the domestic fork industry, but also adopted by Italian company Bolzoni and American company Cascade. The stainless steel product pots, locks, hinges and other polishing production lines we have developed are widely used in various industries such as metal products, hardware electronics, sanitary ware, bathroom, lighting, plumbing, tableware, kitchenware, chassis, cabinets, furniture, locks, automobiles, guide columns, piston rods, ball screws, stainless steel insulated cups, etc. The product has the characteristics of high quality, good surface consistency, high efficiency (saving a lot of labor costs), and excellent environmental performance. Since 2009, the company has exported over 100 polishing (grinding) equipment and production lines to Southeast Asian countries including the United States, Australia, India, Thailand, Indonesia, Saudi Arabia, and the Middle East. Hefei Zhongtong Polishing Machinery Co., Ltd. has become one of the influential enterprises in the research and supply of machine tools and equipment in the field of polishing (grinding) in China. For the past decade, we have provided over a thousand polishing and grinding equipment (production lines) to nearly a thousand customers in various industries both domestically and internationally. We will continue to uphold the principle of "integrity and professionalism" and create value for our customers. Before sales, our professional engineers provide you with process consultation, solutions, product introduction, recommended selection, and pre-sales testing. During sales, we have established a complete process control system for design review, quality control, factory testing, installation and debugging. After sales, we have established a customer file database, regularly follow up on product usage, and provide free after-sales service for our products. While continuously improving the quality of our regular products, we will strengthen the polishing (grinding) production line and robot polishing (grinding) The development of intelligent equipment for polishing and grinding products to create greater value for customers.
