PCD (polycrystalline diamond) is the first-choice edge material for non-ferrous and abrasive-composite machining: aluminum and magnesium alloys, copper, brass, graphite, fiber-reinforced composites (CFRP/GFRP/GRP), and engineering plastics. On suitable workpieces it can deliver a substantial step-change in tool life versus carbide; the actual gain depends on workpiece, parameters, and rigidity of setup, so we size every tool to your application rather than quote a single multiplier.

Where diamond graphitizes — hardened steel, cast iron, high-temperature alloys — c6ex specifies CBN (cubic boron nitride). CBN retains hardness and chemical stability at temperature, enabling finish-turning and milling of hardened components and, for many hard parts, replacing grinding with hard turning.

Geometry matters as much as the edge material. c6ex milling covers face, square-shoulder, copy, and profile work; turning spans indexable inserts and brazed tools with engineered chipbreakers (for example, geometry that controls the long chips typical of ductile aluminum); drilling covers stepped and PCD-tipped designs. Through-tool cooling and modular constructions are available where the application calls for them.

Coverage spans automotive (turbocharger housings, engine blocks, crankshafts, wheel rims), aerospace (composite structures), electronics (PCB machining and de-paneling), and woodworking — wherever non-ferrous or composite material removal is a cost driver.

Each c6ex series is benchmarked against leading tooling (e.g., Harvey Tool PCD end mills, Lach Diamond PCD/CBN inserts) and can be validated per workpiece and parameter on our lab machining center. Tell us your material, machine, and cycle target — we engineer the tool.
