GM Series (Base Model)
The GM series manual cylindrical grinders are the largest of Ecotech's Grinders designed for large rolls and shaft type work. These high precision grinders have been very reliable for the paper and steel industry and the manufacturing of their exotic rolls. These grinders have dead centers, which provide higher repeatability accuracies. The work head has a step pulley drive system providing six variable speeds. They also have a pick feed that can be set to feed on either end of the traverse or at both ends and has a variable feed adjustment. The wheel head must be manually retracted by actuating the feed handle.
