CLAUSING C1860J MANUAL LATHE

Technical Description

The Clausing C1860J is a precision manual engine lathe engineered for versatile metalworking applications. Featuring an 18-inch swing over bed with 60 inches between centers and a 28-inch swing in gap, this machine accommodates large workpieces while maintaining compact footprint dimensions of 108" x 43" x 52". Powered by a 15 horsepower spindle motor, the lathe delivers spindle speeds ranging from 16 to 2000 RPM across three gear ranges, enabling efficient processing of diverse materials. The D1-8 camlock spindle nose with 7 MT taper ensures secure tool holding and quick changeover capabilities. A comprehensive universal gearbox provides 45 inch pitches (2-72), 39 metric pitches (0.2-14), 21 diametral pitches (8-44), and 18 module pitches (0.3-3.5) for extensive threading and feed options. The 3-inch bore accommodates standard tooling, while longitudinal feed rates span 0.0015-0.04 in/rev and cross feeds range from 0.0008-0.02 in/rev, enabling precision finishing operations. The 10.5-inch cross slide travel and 5.1-inch compound slide travel support complex geometries, complemented by a 3-inch tailstock quill with 7 inches travel for center work. An integrated coolant system optimizes chip evacuation and tool life. The induction-hardened, precision-ground bed and hardened headstock gears ensure long-term accuracy and durability. Requiring 230/460-volt, three-phase power, this 4,400-pound lathe incorporates magnetic braking, one-shot lubrication, and optional accessories for enhanced operational efficiency.
