FGC 2--an alternative to creep feed grinding.

The Bridgeport FGC 2 Flexible Grinding Center utilizes milling machine processes with aluminum oxide "cutting tools" (grinding wheels). Use of the Viper-Grinding Process makes the Bridgeport FGC 2 a fast, accurate, and efficient machine for processing parts with the benefits of low cost grinding wheels. FGC 2 uses conventional aluminum oxide grinding wheels and a high-speed wheel changer to grind blades and vanes faster and more efficiently.

Using a two-axis rotary indexer, the FGC 2 can complete parts in one clamping, increase part throughput by grinding faster than conventional creep-feed methods, reduces the risk of scrap by grinding one part at a time, and complete the part with extremely low tool cost per part.

The Bridgeport FGC features a 50hp, 8,000rpm-integrated spindle that incorporates the preferred tooling method for wheel-flange mounting--BT face and taper locating adapters. The base platform is a rigid and heavy grey cast iron, weighing 30,100lb, which can sustain the rigors of dressing wheels and take a respectable depth of cut. Grinding feedrates of 100ipm exceed the speed and agility of traditional creep-feed grinders.

The complete package using dual-arbor diamond roll dressers provides flexibility where it is most needed, in quick changeovers, utilizing software changeover and setups as opposed to hard tooling changeover and setup. Hardinge Inc.,
