luty engine lathe “a power traverse tailstock Heavy duty tailstock, with a large diameter hardened and ground spindle and a hardened insert tang slot, moves under power from the longitudinal feed mechanism by engaging the carriage through an interlock. The tailstock is equipped with a single speed traverse screw and a direct reading traverse indicator providing accurate depth control. Rapid traverse is approximately 200” to 250" per minute. Alternate manual traverse is obtained with the apron handwheel. A heavy duty thrust lock, engaging a rack located in the bed, prevents the tailstock from moving on the bedway under heavy loads.
Four clamping bolts and two saddle clamps insure proper clamping to the bedways. One shot lubrication to tailstock ways with oil reservoir located in the base. box girth design rigid bed Nebel bed design of box girth provides greater rigidity, longer life and precise accuracy by withstanding extreme stress and strain, Thegfront “V” way guarantees alignith its wide bearing surface, al ort to the carriage and all component units.
