LUBRICANTS FOR U.S.A.F. FORGING PRESSES

INTERESTING lubrication applications are involved in the production of heavy precision forgings by means of two new 35,000‐ton and 50,000‐ton hydraulic presses recently installed at the Cleveland works of Aluminium Company of America, who are operating the plant on behalf of the U.S. Air Force. Such heavy precision forgings will make possible the construction of lighter and less expensive components for all types of modern military aircraft and their size will permit one‐piece construction of airframe parts, which formerly required several pieces.
