WEISS MACHINERY WM250AV-F MANUAL LATHE

Technical Description

The WEISS MACHINERY WM250AV-F manual lathe features a precision-ground, hardened V-way bed with a 135 mm width that enhances rigidity and vibration resistance. It accommodates a maximum swing over bed of 250 mm (9.84 inches) and swing over cross slide of 145 mm (5.71 inches), with centers spaced at 550 mm (29.53 inches). The headstock contains an MT4 spindle taper with a 26 mm (1.02 inches) bore, allowing robust workpiece mounting and accommodating standard tooling. The lathe is driven by a 1.01 HP (750W to 1.1 kW range depending on source) motor capable of variable spindle speeds from 50 to 2000 RPM, enabling versatility for different turning operations. It includes independent lead screw and feed shaft, supporting automatic cross and longitudinal feeds with ranges approximately 0.026–0.156 mm/rev (cross feed) and 0.06–0.48 mm/rev (longitudinal feed). Thread cutting capability covers a wide range of metric (0.2–3.5 mm) and imperial (8–56 TPI) pitches, with fully interlocked automatic feed and threading functions. The carriage assembly features a 4-way tool post, maximum cross slide travel of 115 mm, compound slide travel of 50–70 mm, and tailstock quill travel of approximately 70–80 mm with an MT2 taper, supporting taper turning and precise tool positioning. The lathe's compact dimensions (approx. 1150 mm length, 560 mm width and height) and robust iron bed construction provide a stable machining platform suitable for small to medium-sized precision turning tasks in workshop settings. This model balances manual operation with variable speed control and fine feed adjustments for versatile metalworking applications.
