Custom Precision CNC Machining Milling Aluminum Parts CNC Machining Part
CNC Mechanical Parts Stainless Steel Milled Parts
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 3 business days.
Product Details
CNC machining encompasses a wide range of materials, primarily
categorized into three major
groups: plastics, soft metals, and hard metals.
These materials include aluminum, bronze, copper, ceramics, plywood, steel, stone, wood, zinc,
and numerous others.
The choice of material depends on ease of workability and desired properties, with those offering
favorable characteristics often being preferred in CNC milling applications.
| Common Materials | |
| Name | Description |
Aluminum | High machinability and ductility, good strength-to-weight ratio. |
Stainless steel | High tensile strength, corrosion and temperature resistant. |
Mild steel | High machinability and weldability, high stiffness. |
Brass | Low friction, excellent electrical conductivity, golden appearance. |
Copper | Excellent thermal and electrical conductivity. |
Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
ABS | Common thermoplastic, impact resistant, easy to machine. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
| PEEK | High-performance thermoplastic, very high strength, thermal and chemical resistant. |

Application of CNC Machining Parts
CNC machining is a highly utilized subtractive manufacturing process employed across a
multitude of industries.
It plays a crucial role in aerospace, automotive, aviation, transportation, and numerous other
integral sectors.
For instance, in the aerospace industry, the production of airplane components demands an
exceptional level of precision to ensure the seamless functionality of the entire aircraft.

FAQ's
1. A quick guide to CNC machining parameters
In CNC machining, many parameters are determined by the machine operator during the
generation of G-code. Among these parameters, we will focus on the build size and accuracy
of CNC machines.
CNC machines are known for their relatively large build areas, particularly when compared to
3D printers.
CNC milling systems, for instance, are capable of machining parts with dimensions of up to
2,000 x 800 x 100 mm (78” x 32” x 40”), while CNC turning systems can handle parts with
diameters of up to Ø 500 mm (Ø 20’’).
One of the notable advantages of CNC machining is its ability to produce parts with exceptional
accuracy and tight tolerances. CNC machines can achieve tolerances that are even less than half
the diameter of an average human hair, which is approximately ± 0.025 mm or .001’’.
In cases where the tolerance is not specified in the technical drawing, the operator typically
machines the part with an accuracy level of 0.125 mm (.005’’).
2. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
If a particular fillet radius is not specified in the 3D model or drawing, please indicate your
preference.
In the absence of specific instructions, the fillet radii will be added by the machinist based on
their judgment for ease of machining.
As a general guideline, internal vertical edge radii may exceed one-third of the depth, while
internal horizontal edges could be left sharp or have a radius ranging from 0.5mm to 1mm.
3. How quickly can I get my parts?
We can produce high-quality parts in as little as two weeks if you furnish us with comprehensive
2D and 3D CAD models.
However, for more intricate parts with additional requirements or special features, the lead time
may be longer. Feel free to request a quote to obtain precise lead times tailored to your project.
In terms of shipping, the majority of our shipments are dispatched via air freight. The transit time
from China to Europe or North America typically takes a few days.
