KAAST MACHINE TOOLS D-TURN HD480/4000 MANUAL LATHES

Technical Description

The KAAST MACHINE TOOLS D-Turn HD480/4000 is a heavy-duty manual lathe engineered for precision turning operations on large workpieces. Featuring a 37-inch swing and 156.5-inch center-to-center distance, this machine accommodates extra-large components requiring robust machining capabilities. The lathe operates at spindle speeds up to 420 RPM with a 5.9-inch spindle bore, delivering 30 horsepower for demanding cutting applications. Constructed with a heavy FC-30 cast machine bed featuring strong ribbing, the D-Turn HD480/4000 minimizes vibrations during operation, ensuring superior surface finish and dimensional accuracy. The X and Z axes are coated with Turcite B to reduce friction and extend machine lifetime. Precision-ground case-hardened guideways provide consistent accuracy throughout the machine's service life. The machine incorporates a robust multi-plate clutch for driving the main spindle and transmission gears made from hardened and ground high-alloy steel running in an oil bath. With a 0.02mm division value on the X-axis dial and automatic feed rates of 0.03–3.52 mm/rev (X-axis) and 0.06–7.04 mm/rev (Z-axis), operators achieve precise thread cutting and feed control. Weighing 24,200 pounds, this lathe provides exceptional rigidity for heavy-duty applications. The A2-11 turning chuck mount and Ø152mm spindle bore accommodate various tooling configurations. Optional equipment includes larger bore options and infinitely variable speed control, making the D-Turn HD480/4000 suitable for rough and finish cutting of both metal and non-metal workpieces.
