Combining roughing, finishing, and gauging in one station is a distinctive capability of the ECO Hone’s dual-expansion honing system, which will be on display at IMTS booth #N-7040. It can finish bore sizes ranging from 10 to 80 mm. Honing systems typically require separate stations for roughing and finishing because each operation requires different grit sizes on the respective diamond honing tools. The dual-expansion system on the ECO hones allows tools with different grit sizes to be mounted on the same spindle. Separate systems control the mechanisms within the spindle that actuate the roughing or finishing tools. The expansion for roughing is driven by servomotors, whereas the expansion for finishing is hydraulically actuated. The finish honing operation commences automatically after the roughing operation reaches the pre-determined bore size. 
Applications include pinion gears, gear hibs, hydraulics valves, gas turbine components, connecting rods, and more. For more information call (734) 426-1812 or go to [www.nagelusa.com].
