The Hardinge GS 51 lathe features a compact design and collet-ready main spindle that are said to provide increased durability and workpiece accuracy. The A2-6 20C, 15-hp (11-kW) spindle provides speeds ranging to 5,000 rpm. The machine offers a 2" (51 mm) bar capacity and accommodates workpieces ranging to11.10" ( 284 mm) in diameter and 17.95" (456 mm) in length. The chuck size is 8".
The lathe features a 12-station vertical block-type turret, and a one-piece, cast iron, 45-degree base strategically ribbed for rigidity and durability. The X and Z-axis ballscrews, linear roller guides and guide trucks feature a large load rating with minimal friction for low heat and thermal growth, long machine life, maximum static and dynamic stiffness, and overall machining accuracy, the company says. The double-nut hardened and ground ballscrews are laser-calibrated and supported by heavy-duty ballscrew supports.
The lathe is controlled by a FANUC 32-bit 0i-TD CNC. Available options include live tooling, C axis, tailstock, chip conveyor, 280-psi through-turret coolant, an arm-type parts catcher with conveyor, and a tool touch probe.
