Nantong Natel Machine Tool Co., Ltd. Awarded 
Nantong Natel Machine Tool Co., Ltd. (formerly Nantong No.2 Machine Tool Co., Ltd.) was founded in 1965. Having been deeply engaged in the grinding machine manufacturing industry for decades, we are one of the earliest physical manufacturers in China to carry out the R&D, design and production of surface grinders.
Professional Manufacturer of Surface Grinders, CNC Surface Grinders and Precision Surface Grinders
The M71 series are high-efficiency grinding machines with hydraulically driven longitudinal table movement. The cross travel of the wheelhead can be driven hydraulically or manually. On the basis of the original manual vertical lifting function of the wheelhead, a rapid lifting mechanism is added to improve production efficiency. They are widely applied in the processing of various parts for machining, auto parts, fixtures, magnetic steel, molds and other industries.
