Norton's Xtrimium Dual Worm Wheel Performs Grinding and Polishing
IMTS Spark: Norton’s Xtrimium gear grinding wheel from Saint-Gobain Abrasives features a dual-worm design enabling grinding and polishing with the same grinding wheel.
Norton’s Xtrimium gear grinding wheel from Saint-Gobain Abrasives features a dual-worm design enabling grinding and polishing with the same grinding wheel. The wheel’s high-performance vitrified bond section is used for grinding, and a fine-grit resin section is used for polishing the gear teeth. The use of one wheel for the two processes can result in time savings since it eliminates wheel swapping. The wheel provides surface finishes of 1.0 mm Rz and 0.05 mm Rpk, with reduced harmonics (noise).
Because of the high material removal rate creep-feed grinding can deliver in challenging materials, grinding might not be just the last step in the process—it might be the process.
Achieving consistent and quality results from the centerless grinding process requires an understanding of the basic fundamentals. Most application problems associated with centerless grinding derive from a misunderstanding of the basics. This article explains why the centerless process works and how to use it most effectively in your shop.
Understanding grinding wheel fundamentals will help you find the right wheel for the job.
