KAAST MACHINE TOOLS D-TURN HD560/4000 MANUAL LATHES

Technical Description

The KAAST MACHINE TOOLS D-Turn HD560/4000 is a heavy-duty manual engine lathe engineered for demanding industrial turning applications. Featuring a robust 43.5-inch swing capacity and an impressive 156.7-inch center-to-center distance, this machine accommodates large and long workpieces with exceptional rigidity. The spindle bore measures 5.9 inches with an A2-11 spindle mount, providing secure workholding for extended operations. Delivering 30 horsepower with a maximum spindle speed of 420 RPM, the D-Turn HD560/4000 prioritizes torque and precision for heavy-duty material removal. The machine bed is constructed from heavy FC-30 cast iron with strong ribbing to minimize vibrations during extended cutting cycles. Both the X and Z axes are coated with Turcite B to reduce friction and extend machine operational life. Standard features include a 3-axis digital readout (DRO) for enhanced precision, longitudinal and cross rapid feed capability, and a robust multi-plate clutch for main spindle drive. Transmission gears and shafts are manufactured from hardened, ground high-alloy steel operating in an oil bath for durability. The precision-ground guideways ensure smooth, accurate tool holder and tailstock movements with reliable locking mechanisms. At 22,600 pounds, the substantial machine weight contributes to structural stability during heavy machining operations. Optional configurations include faster spindle motors, various chuck sizes, and enhanced tailstock designs. The D-Turn HD560/4000 delivers versatile threading capability in metric, Whitworth, module, and diametral standards, making it suitable for comprehensive production and job shop applications.
