| 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. |
