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.
Product Details
CNC machining can be used for a wide variety of materials, with the most common being
aluminum, steel, brass, ABS, Delrin, and nylon. But really, almost any hard material can be
CNC machined.
| 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. |
| POM | High stiffness, high accuracy, low friction, easy to machine. |
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.

Company Profile
FAQ's
1. What are the benefits of CNC machining?
CNC machining offers several key advantages. It excels in rapid prototyping and the speedy
production of full-scale production parts. With CNC machining, you can achieve exceptional
precision and accuracy, making it ideal for tight tolerance machining across a wide range of
part sizes.
Additionally, CNC machining provides maximum flexibility in terms of volume, pricing, lead
times, as well as material and finish options.
2. What are typical 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 are the default fillet sizes in the absence of specified dimensions from the
3D model or drawing?
When specific fillet dimensions are not provided, we will apply fillet radii that facilitate machining,
as determined by our machinists' judgment. If you require a particular fillet radius, please ensure
it is specified.
In the absence of specific details, typical internal vertical edge radii may exceed 1/3 of the depth,
while internal horizontal edges can be either left sharp or have a radius ranging from 0.5mm to
1mm, depending on the machining requirements.
4. Quality Assurance
At our company, we prioritize customer trust and adhere to established quality management
principles. Our commitment to enhancing customer satisfaction drives us to consistently improve
our performance and capabilities.
With decades of experience, we have a strong track record of meeting stringent regulations and
maintaining compliance with PPAP standards for the automotive, aerospace, and medical device
industries. These industries set high benchmarks that guide our manufacturing processes for all
our products.
