The BALINIT hard-carbon coating is thin, smooth, and has high hardness (40-50 GPa) that makes the coating well suited to applications that require superior wear protection. In addition, the thin, smooth application helps to maintain sharper cutting edges.
For example, at a Malaysian manufacturer producing HDD aluminum alloy baseplates, coated-carbide end-mill tooling exhibited less abrasive wear and produced 95% more parts, with 55% lower production costs than untreated tooling.
The combination of coating hardness along with a low-friction coefficient also can dramatically improve production even with dry machining. In an application involving CFRP and thermoplastics workpieces, for instance, a hard carbon-coated countersink tool produced 180% more parts than an uncoated tool. In another comparison, a coated carbide end mill doubled the parts produced with dry machining, compared to an untreated tool using lubricant.
