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).

  • What Is Single Point OD Grinding?

    Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.

  • A Model Camshaft Grinding Process

    Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
