Secondary Finishing & Inspection Protocols
Select a tab below to inspect our integrated post-machining finishing operations and metrology standards configured specifically for 6061 aluminum components.
Bead Blasting
Removes residual machine cut marks, directional mill traces, and micro-burrs to achieve a uniform, satin-matte finish ready for anodizing or direct assembly.
Standard Anodizing (Type II)
Forms a controlled electrolytic oxide layer providing corrosion resistance and electrical insulation. Available in clear, black, and custom optical color finishes.
Hard Anodizing (Type III)
Delivers an ultra-dense ceramic-like oxide layer up to 50 µm thick for dynamic mechanical assemblies, robotic wear plates, and sliding industrial surfaces.
Frequently Asked Questions: 6061-T6 Machining
Why is Aluminum 6061-T6 preferred over 7075 for housings?
While 7075 offers higher tensile strength, 6061-T6 provides significantly better corrosion resistance, superior weldability, and more consistent anodizing appearance at a more economical material cost.
What standard machining tolerances do you achieve?
Our Mazak 5-axis centers routinely hold linear tolerances down to ±0.005 mm to ±0.01 mm depending on feature geometry, wall thickness, and post-machining surface treatment specifications.
How do you prevent part warping during extensive milling?
We use certified stress-relieved 6061-T6 stock, multi-pass roughing cycles with controlled cooling, and secondary stress relief when removing high percentages of volume on thin-walled enclosures.
What file formats are accepted for technical quoting?
We accept 3D models in STEP, STP, IGES, or SLDPRT formats, alongside 2D PDF drawings containing defined GD&T callouts, thread tolerances, and surface roughness parameters.
