Machining graphite and carbon [SubsTech]

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.

Influence of grinding on graphite crystallinity from

This paper examines the effects of shear stress on the structuralparameters that define the 'crystallinity' of graphite. The results show that highly crystalline graphite samples ground for up to 120 min do not undergo detectable changes in the three-dimensional arrangement of carbon layers but crystallite sizes (Lc and La) decrease consistently with increasing grinding time.
