1994 HARDINGE CONQUEST51SP CNC LATHE

Technical Description

The Hardinge Conquest T-51SP is a CNC turning center from Hardinge's 1990s Conquest Super-Precision line, a collet-ready chucking/bar lathe built around an A2-6, 20C spindle nose with a 2.378-inch spindle bore (2-inch round collet bar capacity) and an AC digital spindle drive rated at 20 hp, with a speed range of 50-4,200 rpm. Machining capacity covers a 13-inch maximum machining diameter and a 22.87-inch maximum turn length, with 6.75 inches of X-axis travel and 22.875 inches of Z-axis travel. The SP configuration adds a bi-directional 12-station vertical turret (6 stations live, 2.4 hp live-tool drive to 3,000 rpm, 1-inch square/1.5-inch round shank tooling) plus a separate 6-station bi-directional end-working turret, full C-axis contouring to 0.001 degrees, a chip conveyor, and high-pressure coolant. The machine weighs approximately 15,000 lbs. Three independent used-equipment dealer records for this model agree closely on these figures. Reported CNC controls differ by production run within the 1990s Conquest line (FANUC 18T on some units, an earlier FANUC OT-C on others built in the early 1990s), so the control fitted to this specific 1994 unit cannot be confirmed and is left blank, as is chuck size, which was not a cataloged spec for this collet-nose model and appeared only as installed tooling on individual as-sold units.
