OEM Custom CNC Machining Milling Service Parts 6063 Aluminum Metal
Accessories Medical Device CNC Machining Aluminum Parts
CNC milling represents a machining process that seamlessly integrates computer numerical
control machining systems with multi-point cutting tools, often in the form of milling cutters.
As a pivotal branch of CNC machining, CNC milling entails securing the workpiece onto a
machine bed and methodically removing material from a solid block.
This meticulous process results in the fabrication of diverse products, encompassing materials
such as glass, metal, plastic, wood, and specialized materials.
Product Details
In custom milling projects, CNC machine shops can work with a variety of metals and plastics,
provided they are suitable for machining.
The prevalent choice for precision CNC machining is aluminum alloys, prized for their natural
corrosion resistance.
Aluminum stands out as a favored material for CNC milling machine prototypes, thanks to its
combination of strength and machinability, enabling the precise fabrication of intricate features
in a single prototype.
Among aluminum alloys, the 6000 series is the most frequently encountered in milling machine
shops. Stainless steel alloys are another common choice due to their resistance to corrosion
and wear.
Additionally, carbon steel, titanium, and nylon—a chemically resistant, robust, durable
thermoplastic—are materials often employed in CNC milling projects.

FAQ's
1. How much do CNC machining materials cost?
The cost of materials in CNC machining can fluctuate significantly due to the extensive array
of available options.
Each material carries its unique price tag, and the inherent physical properties of each material
play a substantial role in determining machining costs.
For those seeking to manufacture metal components, Aluminum 6061 stands out as the most
cost-effective choice. On the other hand, ABS ranks as the most budget-friendly option among
materials.
As for the influence of machining complexity on costs, stainless steel serves as an illustrative
example. Its inherent hardness, surpassing that of aluminum, renders it more challenging to
machine, consequently elevating the overall machining expenses.
2. What are standard machining tolerances?
Typical machining tolerances fall within the range of ± 0.005 inches or 0.13 millimeters.
Tolerances represent the allowable variation for a specific dimension.
For instance, if a CNC machining tool has a tolerance of ± 0.01 millimeters, it means that the tool
can deviate by 0.01 millimeters in each cut.
When provided with a drawing, Our CNC machining service can achieve CNC parts with tolerances
as tight as ± 0.0002 inches. In the absence of a drawing, all CNC parts are manufactured according
to our ISO 2768 medium standard.
We can also work to even tighter tolerances, such as ± 0.025 millimeters or ± 0.001 inches,
when an engineering drawing specifies critical features.
3. What is the typical delivery time and quotation process?
Delivery time is determined based on the complexity of the parts.
For low-complexity parts, the lead time is typically 2-3 days. As the complexity of the parts
increases, the lead time can range from 2-5 days. High-complexity parts may require a lead
time of 5-15 days.
Similarly, the quotation process varies depending on the complexity
of your design.
Quotes can be provided in as little as 1 business day, or it may take 3 or more business days for
more intricate designs.
If you have a design that you would like our team to assess and
provide a quote for, please don't
hesitate to contact us.
