Product Construction & CNC Turning Features
The component features a tapered conical geometry with a precision-machined internal bore. All critical diameters are machined on a common axis to maintain controlled concentricity and stable runout performance. CNC turning processes are used to achieve the tight ±0.0005 inch outer diameter tolerance, making the part suitable for assemblies where alignment accuracy is critical.
As a typical example of precision stainless steel turned components, this part demonstrates excellent repeatability for both prototype and production quantities.
Material Selection & Heat Treatment
416 stainless steel (CRES) is selected for its superior machinability and reliable performance in precision machining. Heat treatment to a minimum hardness of Rockwell C 25 improves wear resistance and dimensional stability, ensuring long-term consistency during service. This material choice is widely used in 416 stainless steel machined parts requiring both precision and durability.
Quality Control & Inspection Process
To meet high engineering and appearance standards, each component is subjected to:
100% visual inspection for surface defects
Dimensional inspection of all critical features
Runout and concentricity verification
Material and heat treatment compliance checks
This inspection process ensures that all delivered parts meet the requirements expected of tight tolerance stainless steel parts.
Typical Applications
Precision mechanical assemblies
Alignment and positioning components
Industrial equipment subassemblies
Aerospace and defense hardware
Custom CNC stainless steel parts
Summary
With controlled concentricity, tight dimensional tolerances, and strict inspection standards, this component represents the quality level expected from professional cnc turned parts suppliers serving industrial, aerospace, and precision engineering markets.
