New Controlled Porosity Open Structure Toolroom Wheels From Norton Abrasives


WORCESTER, Mass., February 19, 2002 -- Announcing Norton NorPor(TM)-a new line of controlled porosity open structured grinding wheels that grind cooler allowing higher metal removal rates in both wet and dry grinding applications.

In both wet and dry grinding conditions, the specially developed uniformly open structure of the Norton NorPor wheel creates greater chip clearance thereby decreasing the possibility of wheel loading. As a result, operators can dress wheels less often, grind more parts per wheel, and reduce the total number of wheels used while generating superior tool and cutter geometry.

During the wet grinding process, the controlled porosity open structure of the Norton NorPor wheel offers the additional advantage of allowing greater coolant flow to the interface between the wheel and the work piece. Greater coolant flow results in significantly reduced temperature at the point of contact. The combination of less heat and greater chip clearance allows toolroom operators to increase infeed rates without burning the work piece surface or reducing wheel life.

To further extend wheel life, Norton NorPor wheels utilize a bond formulated with durable bond posts maximizing the bond's ability to retain abrasive grains.

Norton NorPor wheels are available in four abrasive types: White 38A, Pink 25A, Ruby 48A and Purple 3SGR; and three standard shapes: Type 1, Straight; Type 5, Recessed 1 Side; and Type 7, Recessed 2 Sides.

The specially developed uniformly open structure of the Norton NorPor(TM) wheels creates greater chip clearance, which decreases the possibility of wheel loading and burning of the part being reconditioned. The new Norton toolroom grinding wheels are available in four abrasive types: White 38A, Pink 25A, Ruby 48A and Purple 3SGR; and three standard shapes: Type 1, Straight; Type 5, Recessed 1 Side; and Type 7, Recessed 2 Sides.
