The only effective way to conquer graphite is using diamond coated tools. Generally, diamond coated tools can last 15-20 times longer then uncoated tools. But it also depends a lot on cutting conditions, machine tools and user requirement of surface quality. There are several principles that operators should keep in mind when milling graphite.

Flake-graphite is probably the most familiar of the natural graphite materials. Most people are familiar with the finely powdered graphite used as a lock lubricant, or the "lead" in pencils. Both of these products typically contain flake graphite. As the name implies flake graphite has a distinctly flaky or platy morphology.

Did you google: machining graphite Graphite is *EXTREMELY* nasty to machine, and even working it with hand tools is unpleasant. Apart from being very brittle, if you use any coolant it is likely to form an abrasive slurry which destroys tooling and if it gets in the ways, spindle bearings etc. wrecks your mill or other machine.

We recommend diamond coated end mills for graphite. Here is the reasons why we recommend diamond coating end mills. Diamond coating can enhance the surface hardness of the tool, improve the wear resistance, and fully ensure the machining accuracy of the parts. They offer up to 10 times more tool life than milling cutters with conventional coatings.

For graphite work, climb milling is preferred since chipping begins at maximum and decreases with the heat generated being transferred to the chips. The process creates a cleaner shearing plane, which lessens the wear on the tool, and chips are removed behind the cutter, an essential element for milling graphite.

First, synthetic graphite should be machined dry without the use of liquid coolants. The use of coolants when working with graphite will produce an abrasive slurry when the coolant combines with the fine bits of graphite chips and dust. The coolant fluid will also permeate the graphite material through the open porosity of the material.
