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 machine is a high-efficiency grinding machine equipped with hydraulically driven longitudinal worktable. The cross movement of the wheelhead can be operated hydraulically or manually. A rapid vertical lifting mechanism is added on the basis of the original manual lifting function of the wheelhead to greatly boost production efficiency.
This machine is a high-efficiency grinding machine equipped with hydraulically driven longitudinal worktable. The cross movement of the wheelhead can be operated hydraulically or manually. A rapid vertical lifting mechanism is added on the basis of the original manual lifting function of the wheelhead to greatly boost production efficiency. It is widely applicable for component processing in machinery manufacturing, auto spare parts, jigs and fixtures, magnetic steel, moulds and other industries. The worktable adopts a distinctive double hydraulic cylinder moving structure, which delivers stronger driving force and more compact spatial layout.
