CNC Machining of Inconel & Nickel Alloys
Inconel holds its strength where steel would long since have given up - at high temperature, in aggressive chemistry. That same tenacity is what makes it one of the hardest alloys to machine.
Why it is hard to machine
Nickel alloys work-harden aggressively and conduct heat poorly, so cutting forces are high, heat piles up at the edge and tools fail fast. The hardened layer left by a dull tool then makes the next pass even harder - a cycle that has to be broken deliberately.
Process controls that matter
Aggressive work hardening
Re-cutting a hardened surface multiplies forces. We keep the tool engaged and always cutting under the hardened skin.
Very short tool life
Heat and abrasion destroy edges quickly. Dedicated tooling and enforced tool-life limits protect the part, not just the tool.
Surface integrity
A damaged layer can hit fatigue life. Controlled parameters and finishing passes keep the surface sound.
Tolerances, inspection and documentation
Typical applications
Aerospace and energy components, chemical and process hardware, high-temperature instrumentation, semiconductor and vacuum parts.
