Stainless is everywhere in equipment — and easy to do badly. Here is how to machine it right.
Stainless hardens if you skim it with a dull tool or light passes. Keep a positive, consistent depth of cut so the tool stays in fresh material.
Sharp carbide, generous coolant and rigid setups prevent built-up edge and poor finish.
304 for general use, 316L for corrosion/cleanroom, 17-4 PH when hardened strength is needed.
Usually work hardening or built-up edge — fix with sharper tools and a steadier cut.
More gummy than 304, but very manageable with the right speeds and rigidity.
