Parts Service
CNC, short for computer numerical control, defines a machining process driven by computer
commands. This technology enables faster, more accurate, and intricate part production compared
to manual methods.
CNC machining reduces reliance on manual labor while enhancing precision and complexity.
Although humans are vital for programming and machine operation, the physical machining tasks
are automated. This synergy between human expertise and computer-driven automation ensures
seamless and efficient operations.

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.

FAQ's
1. What cosmetic standards do you guarantee?
Ensuring high-quality finishes, all CNC machined parts undergo standard deburring and
edge-breaking procedures. Critical edges requiring a sharp finish must be explicitly highlighted in
technical drawings.
Surfaces are guaranteed to be free from defects such as scratches, dents, stains, blemishes,
hanging marks, and minor imperfections. Specifically, critical surfaces (primary (a) side, per
technical drawings) will be devoid of mill steps and other marks. On the secondary (b) side,
minor hanging marks and up to 2 minor defects are considered acceptable.
To further enhance surface quality, visual appeal, and wear resistance, a variety of post-processing
and finishing methods can be applied to CNC machined parts.
2. How much does CNC machining cost?
The cost of CNC machining hinges on factors such as complexity, quantity, and lead time.
For an accurate cost estimate, we recommend submitting a 3D CAD model to receive an interactive
quote along with design for manufacturability (DFM) feedback.
Thanks to our proprietary software and automated fixturing processes, upfront non-recurring
engineering (NRE) costs are eliminated. This makes CNC machining economically viable for
quantities ranging from 1 to 200 parts. While prices may align or slightly exceed those of 3D
printing, CNC machining offers superior material properties and surface finishes.
3. What are your tolerances for machined parts?
Our standards for machined parts encompass +.005”/- .005” local tolerances across most metal
geometries and +/- 0.010" for plastics. Notably, these tolerances may vary for larger parts,
particularly concerning flatness after heat treatment.
Achieving an "As Milled" finish for CNC parts necessitates a minimum surface finish of 125.
Fabricated parts adhere to a 0.010” dimensional tolerance and a 1° angular tolerance.
Tapped holes not explicitly marked as features in the CAD model may be machined according
to the specified diameters. Importantly, surface treatments, including anodization, bead blasting,
iriditing, powder coating, etc., will only be applied if explicitly paid for and acknowledged.
