SOUTH BEND SB1046PF MANUAL LATHE

Technical Description

The South Bend SB1046PF is a precision manual lathe engineered for general-purpose metalworking applications requiring substantial capacity and rigidity. This gearhead lathe features a 21-inch swing over bed, accommodating large-diameter workpieces, paired with a 60-inch distance between centers for extended workpiece lengths. The machine delivers 15 horsepower through a robust spindle system with a 3.15-inch bore and D1-8 Camlock spindle mount, capable of achieving speeds up to 1,600 RPM for diverse material removal rates. The 14-inch swing over cross slide provides adequate clearance for tooling operations across the workpiece profile. Weighing 6,182 pounds, the lathe's substantial mass ensures excellent vibration damping and dimensional stability during precision operations. The unit incorporates hand-scraped dovetails on the compound rest and carriage for optimal accuracy, adjustable tapered gibs for wear compensation, and a graduated compound rest swivel enabling beveled and tapered turning operations. Equipped with a micrometer carriage stop and thread cutting capabilities spanning 2 to 72 TPI in inch measurements and 0.4 to 14 mm metric pitches, the machine supports both production and job-shop environments. The gearhead transmission provides reliable speed ranges ideal for various materials. SKF spindle bearings ensure smooth, precise rotation, while Meehanite castings contribute to structural integrity. This manual lathe represents a versatile platform suitable for boring, facing, threading, and general turning applications requiring the balance of power, control, and precision inherent to classic South Bend engineering.
