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
It adopts a symmetrical double-column gantry layout, forming a closed frame structure composed of the bed, double columns and crossbeam. A carriage is mounted on the crossbeam, and the peripheral wheelhead performs vertical lifting movement along the guide rails of the carriage; the carriage moves transversely along the crossbeam guide rails; the reciprocating movement of the worktable is driven hydraulically.

A carriage is mounted on the crossbeam, and the peripheral wheelhead performs vertical lifting movement along the guide rails of the carriage; the carriage moves transversely along the crossbeam guide rails; the reciprocating movement of the worktable is driven hydraulically. The bed and worktable adopt one flat and one V-shaped sliding guide rail pair; the worktable guide rails are plastic-coated wear-resistant guide rails. Both vertical feed and cross feed movements of the peripheral wheelhead are driven by AC servo motors.
