The NTG tool and cutter grinder is designed for quick, precise manufacturing and reconditioning end mills, drills, step drills, taps and form cutters. The machine’s three-station wheel and manifold changer switches wheels in 10 to 15 seconds. The automatic load/unload system, which holds as many as 288 parts, loads and unloads tools ranging to 0.5" in diameter by 8" long to an automated tailstock center in 15 seconds or less.
Linear motors on two horizontal axes eliminate the need for ballscrews and reduce the number of moving parts. The company says this reduces maintenance costs and improves surface finish. It adds that the machine occupies 30-percent less floor space than earlier models because the loader is integrated into the standard enclosure.
