Stainless Steel CNC Milling Requires Careful Heat, Tooling & Edge Control

Stainless steel is widely used for parts that need strength, corrosion resistance, wear resistance, or durable mounting surfaces.

Compared with aluminum, stainless steel generally requires more attention to cutting heat, tool wear, burr formation, and machining strategy.

Why Stainless Steel Machines Differently

Cutting HeatHeat control is important because stainless steel can retain more heat near the cutting zone.

Work HardeningSome grades can harden locally if the cutting strategy is not suitable.

Tool WearTool selection and machining parameters influence edge quality and process stability.

Burr FormationEdges, slots, and drilled features may require additional deburring attention.

Surface FinishBrushing, polishing, passivation, or other specified finishes may follow machining.

Common Stainless Steel Grades

304 Stainless SteelCommon for general structural, equipment, bracket, housing, and corrosion-resistant components.

316 Stainless SteelOften selected where additional corrosion resistance is required by the application.

Typical Machined Features

● Mounting faces

● Pockets and recesses

● Threaded holes

● Slots and cut-outs

● Locating holes and datum features

● Multi-face mechanical interfaces
