SAMSTAR 40 X 240 MANUAL LATHE

Technical Description

The SAMSTAR 40 X 240 is a heavy-duty manual engine lathe designed for precision machining of large workpieces. Featuring a 240-inch distance between centers and 40-inch swing over bed, this machine accommodates substantial components with a 49 3/16-inch swing in gap for enlarged work. The lathe employs a D1-11 spindle nose camlock with a 5-inch bore and delivers variable spindle speeds from 6 to 800 RPM across 18 speed settings. The 20 HP main motor drives the spindle, complemented by a 1.5 HP rapid traverse motor and 1/8 HP coolant system motor for comprehensive operational capability. The machine offers extensive threading versatility with 51 metric thread options (1-240mm), 40 inch threads (14-1/16 TPI), 53 module threads (0.5-120mm), and 42 diametral pitch threads (30-1/8 TPI). The cross slide travel of 22 13/16 inches and top slide travel of 9 7/16 inches enable precise positioning, while the 4-inch tailstock quill with #6MT internal taper provides additional flexibility. Longitudinal feeds range from 0.0037 to 0.9055 in/rev across 64 settings, with rapid traverse reaching 160 in/min. The 2-speed tailstock quill travel extends 12 inches. Weighing approximately 14,330 pounds and measuring 322 inches long by 76 inches wide by 67 inches high, this robust machine is ideal for heavy industrial applications requiring reliable repeatability and substantial cutting capacity.
