WEISS MACHINERY WM850D MANUAL LATHE

Technical Description

The WEISS MACHINERY WM850D is a precision manual lathe engineered for versatile metalworking operations, featuring a substantial swing capacity of 47.24 inches over the bed, enabling machining of large-diameter workpieces. With an extended distance between centers of 472.44 inches, this machine accommodates lengthy components for through-cutting applications. The spindle bore measures 5.12 inches, providing ample clearance for workpiece mounting and tool access while supporting precision tapered roller bearings for smooth, accurate rotation. The swing over the cross slide reaches 26.97 inches, offering significant lateral working envelope for complex turning and facing operations. The lathe features an induction-hardened, precision-ground V-way bed construction that ensures rigidity and dimensional stability during extended production runs. The headstock incorporates hardened, precision-ground gears enabling quick speed changes across a comprehensive RPM range optimized for various materials and cutting conditions. The machine employs an adjustable gibs system on all slideways to maintain tight tolerances and compensate for wear throughout its operational life. Built-in power longitudinal feed facilitates threading operations across metric, imperial, and modular thread profiles. The tailstock provides precise axial positioning for drilling, boring, and center support applications. This heavy-duty platform delivers the rigidity, precision, and versatility required for production environments, tool and die shops, and manufacturing facilities demanding reliable performance and repeatable accuracy in manual lathe operations.
