HMT MACHINE TOOLS L50/2000 MANUAL LATHE

Technical Description

The HMT MACHINE TOOLS L50/2000 Manual Lathe is a robust heavy-duty lathe designed for high-precision turning operations in demanding industrial environments. Featuring a box-type bed construction with flame-hardened guideways, the machine ensures exceptional rigidity and long-term accuracy. The main spindle is supported by Timken taper roller bearings at the front and precision NNK bearings at the rear, minimizing vibrations during heavy cuts and enhancing overall stability. The lathe offers a swing over bed of 39.37 inches (1000 mm) and a swing over cross slide of 26.38 inches (670 mm), accommodating large workpieces with ease. The distance between centers is 78.74 inches (2000 mm), and the spindle bore measures 4.33 inches (110 mm), allowing for the passage of long bars or large-diameter components. The machine delivers a spindle power of 24.79 HP (18.5 kW) and operates at a maximum speed of 450 RPM, providing ample torque for heavy-duty machining tasks. The speed range is 21 forward speeds from 4.5 to 450 RPM and 6 reverse speeds from 9 to 450 RPM, offering flexibility for various cutting requirements. The feed range is extensive, with longitudinal feed from 0.1 to 6.4 mm/rev and cross feed from 0.05 to 3.2 mm/rev, enabling precise control over machining operations. The lathe supports both metric and inch thread cutting, with a lead screw pitch of 6 mm. The tailstock sleeve stroke is 325 mm, and the machine can handle workpieces weighing up to 3.5 tonnes between centers without steadies and up to 5.5 tonnes with two steadies. This lathe is ideal for applications requiring high accuracy, durability, and versatility in heavy machine shops.
