60-hour cycle times. Hardened steel up to HRC 62. Deep cavities with long-reach tooling. When the surface finish on the tool IS the surface finish on the part, there's no room for "close enough."
Mold and die work is different from production machining. You're making the tool, not the part. That means long cycle times, complex 3D surfaces, and finished walls that can't be polished afterward. Ball-nose end mills are your primary tool — and stepover, not speed, determines your surface finish.
Tell us the steel grade, hardness, and smallest corner radius. We'll spec the right ball-nose tools.
