The H series 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 workhead has a step pulley drive system providing 6 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 wheelhead must be manually retracted by actuating the feed handle.
The H169 has a stationary table with a traversing wheelhead. The wheelhead is driven by a DC motor with a rack and pinion feed unit.
All of ECOTECH'S Plain Cylindrical Grinders have a heavy aged cast iron construction, that has been precision machined and hand scraped. The H series has a Hydro-dynamic spindle, and a Hydro-static lubrication system on the table and wheelhead ways. With these special features your grinders will give you many years of trouble free operation and high accuracies.
