Norton Winter Virtified cBN Wheels Reduce Costs Per Part
Vitrified bond technology increases grinding productivity.
Saint-Gobain Abrasives’ Norton Winter Vitron7 cBN grinding wheels feature a vitrified bond specifically designed for the external grinding of cam and crankshafts and internal grinding applications in automotive and bearing industries.
These wheels feature premium cBN grain particles uniformly dispersed throughout the bond matrix for maximum grinding efficiency. This enables manufacturers to achieve substantial increases in the number of finished parts between dress cycles, significantly reducing cycle times and extending wheel life up to 40 percent over existing products. Vitron7 wheels also grind cooler because of a low specific grinding energy (SGE) that ensures minimal residual stress, the company says, for superior part quality with surface roughness degradation reductions of as much as 30 percent.
When ID grinding, low power results in less defection and minimizes taper while maximizing part straightness, according to the company.
The word “diamond” brings the word “expensive” to mind. But when it comes to lapping with diamond superabrasives, start thinking “low”—as in lower slurry consumption, lower slurry cost per hour, lower sludge generation, lower cycle time, lower reject rates and fewer process steps.
Following these 10 steps can help grinding shops produce high-quality tools, increase productivity, reduce breakdowns and extend machine life.
As tooling complexity increases, one might expect in-house tool grinding to gradually fade away. In fact, though, more and more shops are taking advantage of CNC tool grinding’s increased capabilities to improve consistency, flexibility and productivity.
