CNC Turning Stainless Steel Parts Machining Service
We possess the expertise to CNC machine a wide range of components, from straight forward
"as machined" workholding fixtures to intricate geometries.
Our manufacturers utilize a comprehensive array of CNC milling and turning centers, and we
can also accommodate EDM and grinding upon request.
Our capabilities extend to achieving tolerances as tight as 0.05 mm (0.0020 in), and we can
deliver within lead times as short as 5 business days.
Product Details
We work with a diverse range of materials, including carbon alloys, aluminum, brass,
stainless steel, high nickel alloys, and engineered plastics.
If you are uncertain about the best material for your specific application, our expertise can guide
you in selecting the most suitable option, even if it happens to be a material not mentioned here.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks,
a feature that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the
surface appearance and elevating attributes such as wear resistance, corrosion resistance,
and chemical resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining
the final presentation of your custom parts, allowing you to achieve the desired surface
quality and performance characteristics.

Company Profile
FAQ's
1. What's the general surface texture of CNC milled and turned parts?
Typically, as-machined milled parts exhibit a surface roughness of approximately 3.2μm
(with the potential to reach 1.6μm for newer machines).
In contrast, for turned parts, achieving a surface roughness as low as 0.8μm is possible,
ensuring that machining speed adjustments are not always necessary.
2. How Much Does CNC Machining Cost?
The cost of CNC machining a part is influenced by various factors, including:
1. Material: The choice of material affects cost, with materials
like Inconel being more expensive
due to increased tool wear and slower machining.
2. Complexity: Complex features drive up costs, as machining
intricate surface shapes is more
time-consuming.
3. Tolerances: Tight dimensional tolerances increase expenses;
specifying them unnecessarily
on non-critical features can inflate costs.
4. Surface Finish: Achieving mirror finishes demands specialized
tools and strategies, prolonging
machining time and costs.
5. Quantity: Low-volume production costs more per part due to
initial setup and programming
costs spread over fewer pieces.
3. What are your tolerances for machined parts?
For most metal geometries, our tolerances are within +0.005" / -0.005".
For plastics, it's typically +/- 0.010". Tolerances may vary for large parts, especially those requiring
flatness after heat treatment.
"As Milled" finish requires a minimum 125 surface finish for CNC parts.
All fabricated parts adhere to a 0.010" dimensional and 1° angular tolerance.
Tapped holes not explicitly noted in the CAD model will match the specified diameters in that model.
Surface treatments like anodization, bead blasting, iridite, powder coating, etc., are only applied if
paid for and acknowledged in advance.
