Norton's Winter Vitron7 Wheels Optimized for Camshaft, Crankshaft Grinding
Saint-Gobain Abrasives offers Norton Winter Vitron7 cubic boron nitride (CBN) grinding wheels, which feature a high-precision vitrified bond.
Saint-Gobain Abrasives offers Norton Winter Vitron7 cubic boron nitride (CBN) grinding wheels, which feature a high-precision vitrified bond designed for the high-performance external grinding of camshafts and crankshafts as well as internal grinding applications in the automotive and bearing industries. The CBN grain particles are uniformly dispersed throughout the bond matrix for higher grinding efficiency, reduced cycle times, extended wheel life and more finished parts between dress cycles, the company says. Vitron7 wheels also grind cooler thanks to a lower specific grinding energy (SGE) minimizing residual stress and reducing surface roughness degradation.
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.
Wire EDM units that swivel a horizontally guided electrode wire in a CNC-controlled E axis give this shop the workpiece clearance and flexibility to produce complex, high-precision PCD-tipped cutting tools.
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.
