Greenleaf's Xsytin-1 grade ceramic composite inserts

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’.”

Greenleaf Ring Max API ring groove cutter

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.

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.

Step 1 of Finishing Fillets

Finishing Fillets
Consider these finish-machining techniques that can enable you to maximize material removal rates prior to completing accurate, tight-radii fillets.

Greenleaf WG-series inserts

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.

Greenleaf offers the GSN100 silicon nitride ceramic insert

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.

High-Performance Milling
 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.
