J&M TL400B MANUAL LATHE

Technical Description

The J&M TL400B is a precision manual lathe engineered for general-purpose machining operations in industrial and educational settings. This machine features a robust 15.75-inch swing over bed, accommodating workpieces up to that diameter for facing and turning operations. The spindle bore measures 3.15 inches, providing substantial capacity for mounting various cutting tools and work-holding devices. With an 8.86-inch swing over the cross slide, the lathe maintains excellent accessibility for tool positioning and workpiece manipulation. The machine is equipped with a geared headstock that enables rapid spindle speed adjustments across multiple ranges, facilitating efficient transitions between different material types and cutting requirements. The precision tapered roller bearing-supported spindle ensures minimal runout and consistent concentricity for accurate machining. The induction-hardened ground bedway provides superior rigidity and wear resistance, maintaining dimensional accuracy throughout extended service life. Power-feed capabilities in both longitudinal and cross directions enable precise, repeatable cuts while reducing operator fatigue. The adjustable gibs on the slideways compensate for wear, maintaining tight tolerances over time. The tailstock features offset capability for taper turning operations, while the MT3 taper accommodates standard centers and specialized tooling. The machine includes essential accessories such as a 3-jaw chuck for efficient workholding and dead centers for between-centers turning. With its 1.1 kW motor and comprehensive feature set, the TL400B delivers reliable performance for small to medium-sized production runs and prototype work, combining affordability with professional-grade precision machining capabilities.
