Cutting Tools

Greenleaf Corp. introduced its WG-300 ceramic composite  tool material about 25 years ago. The ceramic matrix  is reinforced with silicon-carbide "whiskers” that boost  toughness. Initially applied in the relatively constant cutting  conditions of turning operations, the composite tools  provided a significant increase in productivity when roughing  aerospace alloys. Shops are now using WG-300 tools in hard  milling operations. 

Travis Biggs, applications engineer, technical service, for Greenleaf Corp., offers the nitty gritty on the tools used in this 1 minute and 40 second video featuring a 5/8" ball nose tool followed by the company's Extreme Feed Mill 1" dia., 4-tooth cutting tool.
