Mechanical Finishes
Mechanical finishing processes modify the surface texture of metal components through physical means rather than chemical or electrochemical processes. These techniques are essential for achieving specific surface roughness, removing machining marks, and preparing surfaces for subsequent treatments.
Our partner facilities offer comprehensive mechanical finishing capabilities including precision grinding for tight tolerances, vibratory finishing for batch processing, shot peening for fatigue resistance, and various blasting media for surface preparation and texturing.
Whether you need a mirror polish for decorative applications, a specific Ra value for functional surfaces, or surface preparation before plating or coating, our network provides the expertise and equipment to meet your exact specifications.
- Precise surface roughness control
- Improved fatigue resistance (shot peening)
- Enhanced appearance
- Optimal coating adhesion prep


The Mechanical Finishes Process.
Surface Assessment
Current surface condition evaluated and target finish specifications confirmed.
Process Selection
Optimal media, parameters, and equipment selected for your requirements.
Mechanical Processing
Blasting, peening, tumbling, or polishing performed to specification.
Surface Measurement
Ra/Rz measurements and visual inspection verify finish quality.
Cleaning & Packaging
Parts cleaned, protected, and packaged to prevent surface damage.
Baking (High-Strength Steels)
High-strength steel parts (>180 ksi) are baked at 375°F for 3-24 hours to prevent hydrogen embrittlement. Critical for aerospace fasteners.
Sealing (Optional)
Additional topcoat sealers can be applied for extreme corrosion environments. Organic sealers fill micro-pores for extra barrier protection.
Final Inspection
Coating thickness measurement, visual inspection, and adhesion testing ensure parts meet specifications.
