Machining Graphite - Keys to Success

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.
