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’.”

Road Report: Greenleaf Announcement on Eve of EASTEC Opening

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.
