Product Information

Features

PCBN(Polycrystalline Cubic Boron Nitride) cutting tools are designed to machine extremely hard or abrasive materials at high metal-removal rates. PCBN tools are used in a wide range of machining operations such as milling, grooving, turning, facing, and boring. They are recommended for machining hardened ferrous metals such as hardened steels, cast irons and superalloys.

Characteristics

  • Hardest tools
  • The most thermal conductivity tools
  • High strength property
  • The higher productivity of machining operation
  • The most abrasive material

General Guidelines

In order to get the maximum production rates out of any machining operation, the following guidelines should be closely followed:

  • Use PCD cutting tools to machine only nonferrous metals and nonmetallic materials.
  • Select a rigid machine with enough horsepower to maintain the cutting speed where PCD tools perform best.
  • PCD tools are very effective even when run at conventional carbide speeds.
  • Use PCBN tools for machining ferrous metals of Rc 45 hardness or higher and high-temperature alloys with Rc 35 or higher.
  • Select a rigid machine with enough horsepower to take advantage of the production potential PCBN cutting tools offer.
  • Use negative-rake tools, the largest lead angle, and cutting fluids whenever possible.
