Whisker-reinforced ceramic grade insert for difficult-to-cut materials

Greenleaf Corporation introduces the new whisker-reinforced ceramic grade, WG-700, a completely new ceramic insert. The insert‘s substrate benefits from an optimized whisker load, which improves its crack- and wear-resistance characteristics while increasing its overall strength.
Greenleaf’s new, proprietary “Platinum” nano layered coating provides low-friction machining in both wet and dry environments, high temperature stability, abrasion resistance, oxidation resistance and chemical inertness. The end result is an extremely strong, wear-resistant, mechanical-shock resistant ceramic grade that is capable of much higher metal-removal rates than any other whisker-reinforced ceramic insert, says the company.

“Our goal for WG-700 was to create an insert that could consistently machine high-strength alloys at speeds in excess of 1,000 SFM,” states Greenleaf Corporation’s president, Jim Greenleaf. “Not only did we achieve our goal, but we found that we’d also created a grade that is capable of those extreme speeds at  higher feed rates and with better tool life than any of our other whisker grades.”

The introduction of WG-700 is aimed at delivering comprehensive solutions for machining the new classes of difficult-to-cut materials entering the marketplace from new high-strength alloy materials to composites. As the cost to manufacture these materials increases and profit margins decrease in an ever-competitive global economy, it is becoming more important than ever for manufacturers to maximize their machining processes.
