China CNC Machine Tool Fair is a trade fair for the machine tool and tooling industry, held in Shanghai in even-numbered years. It was first staged in 2000 and has been held continuously since, drawing attention from machine tool manufacturers, supply-chain suppliers and user industries in China and overseas.

Its display spans the production chain around machine tools — metal-cutting and metal-forming machines, non-traditional and laser machining, additive manufacturing, manufacturing cells and industrial robots, and the casting, heat-treatment, injection-moulding and cleaning equipment that supports them, and the CNC systems, components, cutting tools, abrasives and measuring equipment the industry supplies.
