Keeping choppers up & maneuvering: Helicopter company holds critical part tolerances with precision grinding

摘要

To keep police on top of troublemakers and the reporting crews that provide traffic reports and dramatic news updates in the air, the Robinson Helicopter Co., a maker of one of the world's top selling civil helicopters - the type used by police and news crews - relies on precision grinding. The company makes two models of piston-driven helicopters, the R22 two-seater and the R44 four-seater. It grinds flight and safety-critical components, such as clutch shafts for power transmission and spools for steering, to strict FAA standards and tolerances with the help of two Studer S33 and two S21 CNC universal cylindrical grinders from United Grinding Technologies (UGT) (www.grinding.com).
