Greenleaf Appoints Global Manager of Tech Team, Marketing
Jan Andersson has previously worked for Kennametal and Sandvik Coromant.
Difficult Materials Are No Match for Ceramic Inserts
TNG Energy Services Inc. was experiencing inconsistent carbide insert life in valve grooving applications. Greenleaf's Ring Max and face grooving tooling helped to reduce production time and increase reliability.
Greenleaf Corp. Appoints Executive VP
Bernie McConnell, who previously managed Kennametal’s Widia business, will replace current vice president of sales and marketing, David Rydbom.
The Potential for Wider Use of Ceramic Inserts
It’s possible that new phase-toughened ceramic insert technology could be used for more universal milling and turning applications.
Broader Range of Applications Ahead for Ceramic Inserts?
Greenleaf's phase-toughened ceramic inserts could prove that this kind of technology has a future in more universal milling and turning applications.
Consider these finish-machining techniques that can enable you to maximize material removal rates prior to completing accurate, tight-radii fillets.
Ceramic Inserts for Aerospace Applications
Greenleaf’s WG-300, WG-600 and WG-700 whisker-reinforced ceramic inserts are designed for machining high-strength alloy materials and turbine machining operations.
Silicon Nitride Insert Increases Productivity
Greenleaf offers the GSN100 silicon nitride ceramic insert grade to increase productivity during machining of cast iron.
Road Report: Greenleaf Makes Announcement on Eve of EASTEC Opening
Cutting tool manufacturer Greenleaf Corporation shared important news about its Global Productivity Initiative and a new whisker-reinforced ceramic insert grade for high-temp alloys the evening before EASTEC opened in West Springfield, Massachusetts.
Milling Solution for Hardened Metals
The Excelerator milling systems, which uses WG-600 whisker-reinforced ceramic inserts, is designed for high-performance milling in difficult-to-machine materials.
Ballnose End Mills for Ceramic, Carbide Inserts
Greenleaf Corporation’s Excelerator ballnose end mills use both ceramic and carbide inserts in the same qualified cutter bodies to increase performance, tool life and cutting action across a spectrum of materials. The insert geometry prevents excess tool pressure at high metal removal rates, and its strong edges shear material without smearing, the company says.
Ballnose End Mills Have an Interesting Edge
In early summer 2010, I had a long talk with Dale Hill, applications engineer at Greenleaf Corp., the cutting tool manufacturer in Saegertown, Pennsylvania.
Whisker-Reinforced Ceramic Inserts
Designed to machine hard materials such as hard steels and nickel- and cobalt-based super alloys, Greenleaf’s WG-300 whisker-reinforced ceramic inserts are said to provide wear and shock resistance at high surface speeds.
Excelerator Mills are designed for high-performance milling in difficult-to-machine materials using the company’s ceramic inserts. Typical application areas include most hardened materials above 40 Rc and nickel- and cobalt-based super alloys. Ring Max ring-groove cutters are engineered to cut machining time of API ring grooves, the company says.
Ring Groove Cutter Line
Designed specifically for the oil and gas industry, Greenleaf Corporation’s expanded Ring Max line of ring groove tooling is suited for difficult to machine materials. Combined with the company’s WG-300 or WG-600 whisker-reinforced ceramic inserts, the ring groove cutters can reduce cutting times from 30 min. to less than 1 min.
Aerospace On A Diet
The difficulty of close tolerance finishing in both high temperature alloys and titanium is particularly real in the Aerospace industry, where thinwall construction is becoming more common. Read how an insert gave this shop an edge.
Successful Application Of Ceramic Inserts
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
Excelerator® Ball Nose End Mills
Greenleaf's Excelerator® Ball Nose End Mills are the only ball nose cutter that is designed to use both carbide and ceramic inserts in the same qualified cutter bodies - providing more capability and versatility. Greenleaf's ball nose end mills offer better performance, higher cutting speeds, longer tool life and superior cutting action over competitors' mills. The Excelerator® Ball Nose is the perfect machining tool for a wide spectrum of difficult-to-machine materials including high-temp alloys, hard steels, soft steels, stainless steels and more.
WG-700™ Ceramic Inserts
WG-700™ is a completely new whisker-reinforced ceramic insert and is the most sophisticated ceramic insert developed by Greenleaf. WG-700™'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.
