CNC, an acronym for computer numerical control, defines the technology behind CNC machining,
where various machining processes are directed and controlled by a computer.
This computerized automation facilitates the production of parts with increased speed, accuracy,
precision, and the ability to achieve more complex geometries compared to manual machining
methods.
Additionally, CNC machining reduces the need for labor-intensive manual machining tasks that
would otherwise be carried out by humans. Although individuals are not physically machining each
part, their role is crucial in programming and operating the CNC machines, ensuring the seamless
execution of every operation.

FAQ's
1. What formats of the files can you accept?
We can accept most of the 3D file formats like SolidWorks (.sldprt)/ ProE(.prt) / IGES(.igs) /
STEP (.stp). We can also use 2D drawing (.pdf) or AutoCAD (.dwg) for quote against the parts
with simple structure. All the other files formats are not listed above but can be read in
AutoCAD/ProE/SolidWorks/ will be also fine for us.
2. What cosmetic standards do you guarantee?
Our commitment to quality includes standard deburring and edge-breaking procedures for all CNC
machined parts. Any critical edges requiring a sharp finish must be explicitly indicated in technical
drawings. Surfaces are guaranteed to be free of defects such as scratches, dents, stains, blemishes,
hanging marks, and minor imperfections.
Critical surfaces (primary (a) side, as specified in technical drawings) will be void of mill steps and
other marks. For the secondary (b) side, minor hanging marks and up to 2 minor defects are deemed
acceptable.
To enhance surface roughness, visual properties, and wear resistance, various post-processing and
finishing methods can be applied to CNC machined parts.
3. How much does CNC machining cost?
The cost of CNC machining is influenced by factors such as complexity, quantity, and lead time.
To obtain an accurate quote, we encourage you to submit a 3D CAD model, allowing us to provide
an interactive quote with design for manufacturability (DFM) feedback.
Leveraging proprietary software and automated fixturing processes, we eliminate upfront
non-recurring engineering (NRE) costs. This makes CNC machining cost-effective for quantities
as low as 1 to 200 parts. While prices may compare similarly or slightly higher than 3D printing,
CNC machining offers superior material properties and surface finishes.
4. How does compare to other suppliers on price?
While direct comparisons can be challenging, generally, We offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers in
North America and Europe.
