Milled CNC Parts Custom CNC Precision Machining Copper Milling Service Part
CNC machining is presently the prevailing subtractive manufacturing technology, offering a
highly adaptable and sturdy method for crafting tailored metal and plastic components.
Employing CAD models, CNC machines meticulously eliminate material from a solid block using
various cutting tools.
In essence, CNC machining yields components with precise tolerances and remarkable material
characteristics. It is well-suited for individual projects and moderate-volume production
(up to 1,000 parts) owing to its exceptional repeatability.
Nevertheless, it entails more design constraints compared to 3D printing, partially attributable
to the subtractive nature of the technology.

FAQ's
1. Machined Parts Tolerances Overview:
Our tolerances for machined parts are as follows:
Local tolerances of +.005”/- .005” are applicable across most geometries in metals, with a
variation of +/- 0.010" for plastics. Tolerances may differ for large parts, particularly
concerning flatness over large parts after heat treatment.
For "As Milled" finish, a minimum surface finish of 125 is required for CNC parts.
All fabricated parts adhere to a dimensional tolerance of 0.010” and an angular tolerance of 1°.
Tapped holes not explicitly called out as features on the quoted CAD model may be machined to
the diameters specified in that model.
Surface treatments (e.g., anodize, bead blast, iridite, powder coat, etc.) will not be applied unless
explicitly paid for and acknowledged.
2. What's the general surface texture of CNC milled and turned parts?
In the realm of CNC machining, the general surface texture of as-machined milled parts typically
exhibits a roughness of approximately 3.2μm (1.6μm for relatively new machines).
On the other hand, turned parts can achieve a finer surface with a roughness of 0.8μm.
Notably, this level of surface quality is attained without the need to adjust the machining speed.
3. Understanding CNC Machining Costs:
The cost of CNC machining a part is influenced by various factors, including:
1. Material: The choice of material significantly impacts cost. Machining materials like Inconel are
more expensive due to increased tool wear and slower cutting speeds compared to materials like
aluminum.
2. Complexity: Parts with complex features are more expensive to machine. For instance,
components with intricate surface shapes incur higher costs than those with flat surfaces.
3. Tolerances: Tight dimensional tolerance requirements contribute to higher costs.
Over-specifying tight tolerances on non-critical features can increase CNC machining expenses.
4. Surface Finish: Achieving mirror finishes demands specialized tooling and machining strategies,
prolonging machining time and elevating costs.
5. Quantity: Low-volume production is inherently costlier per part than large-volume production.
The higher fee stems from spreading initial setup and programming costs over fewer parts.
