Graphite Machining: The three major types for graphite machining are ball end, bull nose, and square end. Diamond-coated carbide tools are used to extend the tool life when cutting EDM electrodes. When cutting graphite, abrasive wear is where the difficulty lies. Cutter path and technique are not as critical, so usually the electrode shape ...

Graphite and carbon are generally machined dry without using Cutting fluids (coolants).If coolants are used in some machining operations (grinding, honing, polishing) the workpiece should be dried at 300-400°F (150-200°C) to remove liquids absorbed by the material.

Spindles for graphite machining should provide very high speed, but clearly require less power than for hard die milling applications. Maximum spindle speed should be at least 20,000 rpm, and preferably 25,000 rpm or more. Because high spindle speeds and feedrates are used, the amount of thermal growth when machining graphite can be ...

End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts. R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.

For graphite machining, a CVD (Chemical Vapor Deposition) diamond coating is recommended whenever possible to maximize tool life and tool performance. These coatings are grown directly into the carbide end mill, improving the hardness and leaving the tool with a coating layer that is 5 times thicker than a PVD Diamond Coating.

Luckily I was doing the feed by hand, so I was aware of the increase in feed pressure needed to cut the graphite. The HSS mill felt and looked sharp, but would not cut, even with high feed pressure. The HSS mill made it to about 25 holes before it was completely unable to cut the graphite. 05-03-2009, 07:27 PM #10.
