Mechanical Carbon Machine Parts | Pumps & Systems

Mechanical carbon materials contain graphite, which is relied on for its self-lubricating characteristics. Mechanical carbon materials can be an effective solution-and sometimes the only workable solution-for moving/movable machine parts where rubbing must occur with low wear and low friction, and oil-grease lubrication cannot be used.

Machining Graphite - Keys to Success

Essentially the graphite will act as a sponge, as capillary action draws the coolant into the open pores. This contamination will cause problems when the graphite is used in an application that requires the inert nature of the graphite material. Second, the starting raw graphite material should be dry before machining.
