Projects Stainless Steel Machining
This stainless-steel machining example focuses on a 1200 × 800 × 500 mm recorded envelope and a project-specific ±0.005 mm requirement. It helps engineering teams define the exact grade, controlled feature, datum transfer, thermal considerations and measurement conditions before 3-axis / 4-axis CNC milling is quoted.

±0.005 mm on the specified feature
“Stainless steel” is not a complete material specification. Grade and condition influence work hardening, cutting response, corrosion behavior and polishing. The drawing must identify the feature linked to the ±0.005 mm value, its datum relationship and the final surface condition instead of applying that tolerance to the full part by default.
Tool engagement, heat generation and tool condition require attention in stainless steel. The route should avoid unnecessary rubbing, protect the reference surfaces and leave a stable allowance for the feature that receives final control.
A large envelope and several machining orientations can amplify thermal drift, tool deflection and datum-transfer error. Setup references and in-process checks should therefore be tied to the functional drawing scheme.
The ±0.005 mm value must be assigned to an identified feature with an agreed measurement method. Part temperature, support condition, surface state and measurement timing may matter when the tolerance is close to process or inspection uncertainty.
Drawing and Grade Review → Datum and Feature Definition → Multi-Setup Planning → Controlled Rough Milling → Thermal Stabilization and Finish Passes → Feature-Specific Inspection
Polishing is coordinated with dimensional acceptance so the final surface condition matches the drawing requirement.
CMM measurement may be used for geometric relationships; micrometers, bore gauges or a height gauge may suit accessible features. Surface roughness measurement is added when specified. The measurement environment, support and part temperature are defined during drawing review for the ±0.005 mm feature.
This example helps customers decide which stainless grade, feature, datum and measurement condition must be stated before a tight-tolerance stainless component can be quoted responsibly.
Large H13 tool-steel work where material condition, datum transfer and polishing allowance shape the machining plan.
Large aluminum milling where alloy, stock flatness, workholding and cosmetic surfaces guide the finishing plan.
420 stainless machining where hardness condition, heat-treatment sequence, stock allowance and polishing drive the route.
Provide the exact stainless grade, controlled drawing, datum scheme, critical feature, quantity, final finish and required inspection documentation.
