RYAZAN 1H65/5 MANUAL LATHE

Technical Description

The Ryazan 1H65/5 is a heavy-duty manual engine lathe designed for large-scale turning operations. This 40" × 204" center distance machine features a robust cast iron construction with hardened ways, providing excellent rigidity and accuracy for precision work. The lathe offers a 41" swing over bedways and 30" swing over the cross slide, accommodating substantial workpieces up to approximately 120" in length. Equipped with a variable-speed spindle operating from 5 to 500 RPM, the machine delivers 9.5 kNm of maximum spindle torque through a 5.25" through-hole. The 39.5" diameter 3-jaw chuck securely holds cylindrical stock, while dual steady rests enhance stability during extended turning operations. Power-driven features include rapid traverse and a powered compound for efficient taper turning, complemented by a 4-way turret toolpost for versatile tool changes. Threading capabilities span both metric (1–96 mm) and imperial (24–1/4 tpi) pitches, making this lathe suitable for diverse applications. The machine is powered by a 30 HP motor at 220/440 volt, providing ample cutting force of 41 kN. A 2-axis digital readout system enables precise dimensional control, while the taper turning attachment extends the machine's operational flexibility. This equipment represents a substantial production lathe suitable for job shops, contract manufacturers, and heavy industrial applications requiring reliable, manual control of large workpiece machining.
