Cazeneuve 28" Swing x 60" B.C. Geared Head Engine Lathe HB725 Inch/Metric Thread

1987 Cazeneuve HB725 High-Precision Heavy-Duty Engine Lathe

28" Swing x 60" Centers | Legendary French Engineering | Workhorse Precision

Available for immediate acquisition is a 1987 Cazeneuve HB725, the "gold standard" of conventional heavy-duty lathes. Renowned in the aerospace and defense industries for its peerless rigidity and "toolroom" accuracy in an industrial frame, the HB725 is a machine that bridges the gap between a standard engine lathe and a precision instrument. Built in the late 1980s, this "MB" generation unit features the refined mechanicals and hardened ways that made Cazeneuve the premier choice for shops that cannot compromise on tolerance.

Key Features & Performance Benefits

1. Unrivaled Vibration Dampening With a machine weight exceeding 7,000 lbs, the HB725 uses a massive, triangulated cast-iron bed designed to absorb harmonic vibration. This allows for superior surface finishes even when performing heavy-interrupted cuts or high-speed finishing.

2. Precision Spindle & Headstock Cazeneuve’s unique spindle bearing arrangement ensures thermal stability and incredible runout accuracy. The 18 HP motor provides the torque necessary for large-diameter turning while maintaining the sensitivity required for delicate, small-batch work.

3. Universal Threading Capability Equipped for both Inch and Metric threading, the HB725 features the famous Cazeneuve "Quick-Change" gearbox. The 127-tooth wheel allows for nearly instant transitions between thread systems, significantly reducing setup time for diverse job shop requirements.

4. Industrial Ergonomics Features a "Reaction Armour" apron that allows for instantaneous stops via the single-control lever or by hand, providing the operator with unmatched "feel" and safety during critical maneuvers.
