Fixed Abrasive Fine Grit Wheels Achieve Superior Finishes, Flatness and Parallelism


-- Norton superabrasives diamond and CBN wheels prove to be superior to lapping and conventional grinding of automotive and beating components --

Worcester, Mass., June 5, 2002 --Norton Abrasives has launched fine grinding diamond and CBN wheels with an innovative "button" structure designed to allow improved coolant flow into the grinding zone. Powdered metal, steel and other ferrous materials can be ground without burning or other metallurgical damage. The advanced bond technology used in these Norton fixed abrasive fine grinding wheels ensures consistent wheel-to-wheel performance and superior part geometry, without the need for lapping and conventional grinding.

Finished parts can be produced up to 10 times faster and per-part cost can be lowered by as much as 30 percent in double-sided grinding applications, with the highest parallelism and uniformity. In a production application of a powdered metal component, the Norton fixed grit CBN wheel was used to finish the component to a flatness of 30u" and finish of 8 to 15 m Ra. In a second steel application, the fixed abrasive CBN wheel achieved a flatness of 80u" and a finish of 8 to 15 m Ra.

The Norton Abrasives fine grit "button" wheels are available in 2A2TSSA shape in diameters of 4.5 to 45.6 inches and grits 120# to 800#. Standard wheel sizes are 18, 18.7, 31.1, 34.8 and 45.6.inch diameters.
