At the sharp end - Coating and geometry developments improve cutting performance and tool life, while innovative and collaborative work addresses specialised production issues

摘要

COATING developments included Sumitomo's Auroracoat, a diamond-like carbon (DLC) coating which supports dry machining of aluminium. Structure of DLC is a mixture of those found in diamond and graphite, and the coating delivers high hardness, good wear properties and excellent resistance to chip adhesion. It exhibits a low friction coefficient when used without lubricant, so eliminates the need for coolant.
