Greenleaf's Excelerator Available in Coarse and Fine Pitch Designs
Westec 2019: Greenleaf’s Excelerator end and face mills are designed for high-performance milling in difficult-to-machine materials using either carbide or ceramic inserts in the same cutter bodies.
Ceramic Insert Grade Effective in Variety of Difficult Materials
Eastec 2019: Greenleaf Corp.’s Xsytin-1 is a phase-toughened ceramic insert grade developed to complement the company’s ceramic insert cutting tools.
Ceramic Milling Products on Display
Eastec 2017: Greenleaf Corp. will showcase its full line of carbide and ceramic inserts and cutting tools.
Ceramic Insert Grade Has Broad Range of Applications
When Greenleaf’s staff of researchers started exploring what they could do with a new manufacturing method to induce internal crystal growth within a silicon-nitride-based ceramic for forming ceramic composite cutting tool inserts, they "got pretty excited," as the story goes. They even named the new grade Xsytin—as in “excitin’.”
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 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.
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.
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.
