The answer lies in combining the graphite with a fast evaporating solvent. In other words: the graphite powder is mixed with a solvent that penetrates the component, and then quickly evaporates to leave a powdery graphite deposit. Meaning, you get the benefit of a penetrating lube without the risk of leaving much oily residue.

Only diamond (preferable) or carbide tools may be used for cutting graphite. 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.
