The WEISS MACHINERY WL1680T manual lathe is a heavy-duty precision machine designed for large-scale machining tasks. It offers a maximum swing of 66.14 inches, allowing for the turning of substantial diameter workpieces. The lathe's centers span an impressive 472.44 inches, accommodating long shafts and extended parts. Its spindle features a robust 5.12-inch bore, enabling machining of sizable through-holes and facilitating the use of large-diameter workpieces or tooling. The swing over the cross slide is 47.24 inches, which ensures versatility and flexibility in operations involving significant cross-sectional beam loading. This model incorporates a hardened and precision-ground rectangular three-guide rail bed for superior rigidity and accuracy during heavy-duty cutting. The headstock design includes precision tapered roller bearings supporting the spindle, contributing to high stability and smooth rotation. Speed control is typically managed by a geared headstock with rapid speed-changing capability, optimizing machining conditions for different materials and cutting tools. Adjustable slideway gibs enable fine-tuning for reduced wear and enhanced precision in carriage and cross-slide movements. This lathe is suitable for machining a wide range of materials including high-speed steel and hard alloy steels, supporting diverse industrial applications requiring large part fabrication with high accuracy.
