J&M TN560 MANUAL LATHE

Technical Description

The J&M TN560 Manual Lathe is a robust engine lathe designed for precision metalworking with a maximum swing over the bed of 22.05 inches (560 mm) and a spindle bore diameter of 4.13 inches (105 mm). It features a swing over the cross slide of 12.6 inches (320 mm), allowing for a range of workpiece sizes and versatility in turning operations. The lathe’s construction supports heavy-duty machining with a wide bed and a taper spindle bore (typically M.T. 7), ensuring rigidity and accurate spindle alignment. It incorporates a manual four-step variable spindle speed system, permitting fine control of spindle RPMs typically ranging from approximately 27 to 1630 rpm, optimized for different machining tasks. The machine includes a tailstock with an MT5 taper quill travel, aiding in the support of longer workpieces during machining. The tool post can accommodate multiple tool holders, enhancing operational efficiency for multi-tool setups. Powering the machine is usually a main motor rated from 7.5 to 11 kW, supporting substantial cutting loads with steady coolant pump operation to maintain spindle and tool thermal stability. Overall, the TN560 is engineered for versatile industrial turning applications, offering significant swing and spindle bore dimensions combined with durable construction, suitable for medium to large workpiece machining in workshops requiring manual control and precision.
