Norton ׀ Saint-Gobain Abrasives announced the introduction of its new Norton Xtrimium range of gear solutions for high-performance gear grinding in extreme, tight-tolerance environment. The newly structured portfolio of gear grinding products is specifically designed by category to provide higher profile accuracy, enhanced form holding and burn-free grinding in worm, profile and bevel applications.
Highlighting the new range is an innovative dual-worm wheel design that enables two operations in one grinding wheel, substantially saving time and cost. “In today’s increasingly stringent industry requirements for higher accuracy and improved surface finishes, our new high-performance Xtrimium grinding wheels are engineered to deliver the highest quality gear grinding solutions,” said Jim Gaffney, sr. product manager, Norton ׀ Saint-Gobain.
Norton Xtrimium dual-worm grinding wheels feature a unique design with a high-performance vitrified bond section for grinding and a fine-grit resin section for polishing the gear teeth, enabling one wheel to perform what traditionally required two wheels. Substantial savings in wheel costs and productivity via the elimination of wheel swapping, can be achieved with the Norton design. In addition, improved surface finishes of Rz = 1.0mm and Rpk = 0.05mm, and reduced harmonics (noise) are realized. The Norton Xtrimium Dual-Worm grinding wheels can also be adapted to existing machines.
The Norton Xtrimium Gear Grinding Platform also covers the whole range of gear grinding processes and leverages the whole spectrum of Norton grains and bond technologies to match each customer's requirements, whether with:
- Worm grinding wheels featuring micro-structured ceramic grain and providing free cutting action and wheel homogeneity, allowing constant performance throughout the wheel thickness for the life of the wheel. Superior grinding rates and increased form holding without burn are achieved with these worm grinding wheels.
- Profile grinding wheels, which are suitable for deep profile gear grinding. The wheels feature high porosity and permeability, create exceptionally high material removal rates, and friction-free grinding.
- Bevel grinding wheels featuring a highly porous bevel formation for extremely fast, burn-free cutting.
Related Glossary Terms
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.
