Chongqing Hengbo Machinery Manufacturing Co, Ltd. is a company specialising in the research, development, production and sales of high-speed, high-efficiency and high-precision CNC grinding machines.

The company is located in Luohuang Industrial Park, Zone B, Jiangjin District, Chongqing, with extremely convenient transport links. Officially established in 2007, the company covers an area of 57 Mu (approx. 38,000 m²) and has a complete manufacturing process for high-precision CBN grinding machines. The company currently employs over 130 people and has an annual production value of over 100 million RMB.

Hengbo has strong technical expertise, modern manufacturing processes and advanced testing equipment. The company holds several national patents and employs both technical experts and highly skilled professionals with many years of practical experience. Based on many years of experience in grinding technology, Hengbo has successfully developed a series of mature products, including high-speed CBN external cylindrical grinding machines, CBN face grinding machines, CBN crankshaft grinding machines, CBN valve grinding machines and combined internal and external cylindrical grinding machines. These products are widely used in cutting-edge industries such as aerospace, new energy vehicles (and internal combustion vehicles), and general mechanical manufacturing, both domestically and internationally. Hengbo has repeatedly broken through the technological dominance of foreign suppliers and occupies a leading position in the field of high-speed CNC cylindrical grinding.

In order to offer the automotive industry an even better service, the company developed a hydrostatic spindle with a grinding wheel peripheral speed of 120 m/s back in 2008. Based on this, the CBN crankshaft grinding machine was successfully developed in 2012 - a product that already made a profit in the same year of development, which is considered a sales success.
