Custom Machined Aluminum Parts Machining CNC Parts CNC Parts Machining Service
Our custom CNC machining service operates through the prevalent subtractive manufacturing
technology, CNC machining, making it an optimal choice for the fabrication of personalized metal
and plastic parts suitable for prototyping and production applications.
The process involves the use of CAD modeling software and G-code to guide CNC milling and CNC
turning machines in the precise removal of material from solid workpieces.
This results in the creation of robust components characterized by tight tolerances and a diverse
range of material properties, encompassing both mechanical and chemical aspects.
The service is particularly well-suited for individual projects and productions with moderate
volumes, leveraging the advantages of automation and high repeatability.
Product Details
CNC machining of aluminum offers distinct advantages that streamline and enhance the
manufacturing process.
Numerous aluminum grades can be efficiently worked with cutting tools.
Aluminum chips readily and is relatively malleable, resulting in machining speeds up to three
times faster compared to iron or steel.
Other benefits include:
1. Machinability
2. Corrosion resistance
3. Strength to weight ratio
4. Electrical conductivity
5. Anodization potential
6. Recyclability

Company Profile
FAQ's
1. Do you offer Quick-Turn CNC Machining?
Absolutely! We provide rapid turnaround times for quick-turn parts, with many available in just
3-4 days. Additionally, we offer an expedite option, and our dedicated team collaborates closely
with you to meet your most urgent deadlines.
2. What type of surface finishes does provide?
We provide an extensive range of finishing services to achieve virtually any desired look and feel
for your parts. Our offerings include treatments for metal, texturing for plastic injection mold tools,
painting for both metal and plastic, and a variety of other options. Learn more about specifying the
surface texture you desire in our blog.
3. Can passivate my parts?
Passivation is a treatment that alters the surface chemistry of certain types of metals. We provide
passivation services for corrosion protection, enhanced durability, improved aesthetics, and more.
4. What are standard machining tolerances?
The standard machining tolerance is ± 0.005" or 0.13mm, representing the allowable range for a
dimension. For instance, if a CNC machining tool has a tolerance of ± 0.01 mm, it implies a
permissible deviation of 0.01 mm in each cut.
With a provided drawing, our CNC machining service can achieve part tolerances as low as
± 0.0002 in. In the absence of a drawing, all CNC parts adhere to our ISO 2768 medium standard.
For projects demanding tighter tolerances, ±0.025mm or ±0.001", we can accommodate with an
engineering drawing specifying critical features.
