Chaoyang Bowen CNC Machine Tools was established in 1965 and transformed from Chaoyang Machine Tools (1965-2003) to Chaoyang Bowen CNC Machine Tools in 2003. It is a designated professional manufacturer of vertical grinding machines for the Ministry of Mechanical Industry and a member of the China Machine Tool Industry Association and the China Molding Industry Association. With a total asset of 61 million yuan, the company currently employs 260 people. In 2011, it achieved an economic income of 70 million yuan and a profit and tax of 6.7 million yuan. The company has a technical development department, which has been awarded the title of municipal-level technical center, and employs 70 engineering and technical personnel. It primarily focuses on the research and development of new products, including vertical shaft circular table surface grinding machines, CNC vertical internal cylindrical face grinding machines, CNC vertical contour grinding machines, CNC lathes, and movable tool grinding machines for heads.

The company is equipped with a Quality Control Department and a Metrology Laboratory, featuring key measurement and testing equipment such as the GLOBAL CMM bridge coordinate measuring machine, MJS5C dual-frequency laser interferometer, TH-140 Rockwell hardness tester, CS-282 carbon-sulfur microcomputer numerical control automatic analyzer, and 7277 spectrophotometer. In January 2005, the company passed the ISO9001-2000 quality system certification, ensuring that the products are consistently controlled by the quality system from design to inventory service.

Chaoyang Bowen CNC Machine Tools specializes in metal cutting machine tools, including the M74 series vertical spindle horizontal surface grinding machines, M74 series vertical spindle horizontal die grinding machines, MK28 series CNC vertical internal cylindrical face grinding machines, MK85 series CNC vertical contour grinding machines, MK74 series CNC vertical grinding machines, MA72 series movable head tool grinding machines, C51 series and C52 series vertical lathes, and CK51 series and CK52 series CNC vertical lathes, among other machine tools. The "Chaoji" machine tools hold a professional status in the domestic market and essentially represent the production level and development direction of China's vertical grinding machines, selling across provinces, municipalities, and autonomous regions domestically, with some products exported to North America, Asia, and Africa. Our company dominates the machine tool market with its superior product quality, comprehensive after-sales service, and sound management system. Each product undergoes rigorous quality management, earning the recognition and approval of clients worldwide.

Chaoyang Bowen CNC Machine Tools is a professional manufacturer of vertical grinding machines in China, primarily producing vertical spindle circular table surface grinding machines and vertical spindle circular table mold grinding machines. We offer five series and 35 varieties, with six varieties domestically produced. Our product level ranks among the top in the country, essentially representing the production level and development direction of China's vertical spindle circular table surface grinding machines, CNC vertical contour grinding machines, and head-moving tool grinding machines. The market share of vertical grinding machines reaches 60%. Our company independently developed and produced the MK28 series CNC vertical internal cylindrical face grinding machines in 2004, and in 2006, we independently developed the MK85 series CNC vertical contour grinding machines, obtaining a national utility model patent. In 2007, we developed the VGK CNC vertical universal grinding machine and CK5116 CNC vertical lathe, which were well-received by users. In 2008, we developed the CK5225 CNC lathe, and in May 2009, the MK2880Z CNC grinder. In 2010, we developed the MKQ7450/MKQ7475 lightweight single-axis CNC surface grinding machine, upgrading the existing vertical spindle circular table surface grinding machines. In 2011, the MK2860TJ product, designed for the valve industry, overcame the difficulty of processing the sealing part of the three eccentric butterfly valve, establishing a professional position. The MK72800-4.5 head-moving vertical spindle rectangular table surface grinding machine was designed and developed for the first time and launched into the market. The processing method and appearance structure of the M7475D sector sanding disc chuck design were awarded national invention patents and utility model patents, and the linear guide rail injection molding process was granted national invention patents and utility model patents.

Chaoyang Bowen CNC Machine Tools has established a comprehensive sales and after-sales service system, with products distributed nationwide. Sales and after-sales services are conducted regionally across the country.

     公司产品还出口到北美经济贸易区、埃及、泰国、新加坡、印度尼西亚、马来西亚、香港等十多个国家和地区，同美国S&S公司、香港港津贸易发展等单位建立了长期的销售业务往来，成为该地区立式磨床的供应商，与德国REFORM公司建立了技术开发、市场营销全面战略合作，共同开发国内、国际市场。
