Product Information

Features

PCD(Polycrystalline Diamond) cutting tools are prepared and used under the conditions which will provide the highest machining performance. PCD cutting tools are capable of greatly improving efficiency, reducing scrap parts, and increasing the quality of the products when used to machine nonferrous and nonmetallic materials.

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.
