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.
Editor PickRobotic Cell Cuts Cycle Time, Improves Part Quality
Sew-Eurodrive Inc. worked with Okuma America’s authorized systems dealer, Gosiger Automation, to design an automated cell that includes an automatic, magazine bar feeder that loads 6-ft. lengths of barstock into the machine. The shop also switched to an Okuma twin spindle, twin turret turning center so all of the machining operations are completed in one setup, thus eliminating additional fixtures and operator intervention. The resultant system reduces cycle times and requires much less operator involvement. As a result, production time per part was more than cut in half – from about 5 minutes to 2 minutes, 20 seconds.
