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
This type of machine tool is a high-efficiency grinding machine with hydraulically driven longitudinal table movement. The cross movement of the wheelhead can be driven hydraulically or manually. A rapid vertical lifting mechanism is added on the basis of the original manual lifting function of the wheelhead to boost production efficiency. It is widely applicable for component processing in machinery manufacturing, auto parts, jigs and fixtures, magnetic steel, moulds and other industries.
