EXPAND MACHINERY GHT-618 MANUAL LATHE

Technical Description

The Expand Machinery GHT-618 Manual Lathe is a precision toolroom lathe featuring an 11-inch swing over bed and 18-inch distance between centers, suitable for detailed metalworking tasks. It is powered by a robust 3 HP electronic variable-speed inverter motor delivering spindle speeds from 130 to 4000 RPM, allowing fine speed control for varied machining requirements. The lathe includes hardened and ground bedways for enhanced stability and precision. The cross slide travel measures 7.5 inches with a 3-inch compound slide travel, complemented by a quick-action compound slide motion of 0.1 inch for precise thread pull-out adjustments. The tailstock is equipped with an MT #2 quill offering 3.75 inches of travel with dual inch and metric graduations. Threading capabilities cover 36 inch threads ranging from 11-108 TPI, facilitated by a threading gearbox that operates without the need for change gears. The lathe also features power feeds in both cross and longitudinal axes, dual reading inch/metric position indicators on all axes, and thread length control stops with fine trip-out adjustments for improved threading accuracy. Maintenance is optimized via a one-shot lubricator servicing carriage and cross slide ways and gib surfaces. The machine weighs 1,804 lbs and has dimensions of approximately 74 by 30 by 66 inches. This combination of precise mechanical specifications and advanced control features supports high-accuracy manual machining operations in toolroom and workshop environments.
