Especially if you are not prepared to work with it's unique and messy properties. As a custom graphite machining facility as well as a supplier of graphite material blanks, we have answered may customer questions over the years about the difficulty of machining graphite correctly.

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.Copy milling and form grinding. Preferred machining methods for the manufacture of electric Discharge Machining (EDM) electrodes are milling and high-speed milling, for-grinding and EDM-cutting. Since EDM fine-grained graphite grades still have a volume of open pores of 10 to 15 %, they can be impregnated with copper.

Graphite is very abrasive due to its bond strength between individual carbon molecules. 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.Graphite and carbon are abrasive materials and cause cutting tools a high level of wear. As a result, the cutting tools used are normally made of diamond or micro-grain carbide. Graphite is machined in much the same way as metal, whether it's via methods such as turning, grinding, sawing or CNC milling.

CBN inserts, which are widely used for turning hard metals like cast iron, are being used for milling because of tougher grades and the development of special toolholders. Hard turning, as a substitute for grinding, has benefited from the advances in machine technology, especially in the rigidity and power of CNC turning centers.Therefore, how to prevent the workpiece from crushing, improve the surface quality and reduce the cost of cutting tools has become an important issue in graphite electrode machining. Conventional turning, milling and grinding methods are usually used to meet the needs of machining simple shape electrodes.
