Stainless steel grades commonly applied for CNC machining:
AISI 304 / 304L
AISI 316 / 316L
AISI 303
AISI 301
AISI 420
Material selection is defined by machining behavior, strength requirement, and working environment.
Manufacturing Method
CNC milling
CNC turning (for rotational features)
Multi-face machining in single setup
Secondary operations: drilling, tapping, threading
Dimensional Capability
Typical tolerance: ±0.02 – ±0.05 mm
Controlled flatness and perpendicularity
Stable concentricity for rotational features
Actual tolerance depends on geometry and material condition.
Surface Condition
Machined surface
Brushed finish
Polished finish
Passivated surface
Sandblasted surface
Blackened or plated surface (on request)
Surface treatment is applied after dimensional verification.
Equipment Used
CNC machining centers
Precision CNC lathes
Rigid workholding fixtures
