CNC machining, or computer numerical control machining, is a widely embraced manufacturing
method utilizing automated, high-speed cutting tools to shape designs from metal or plastic stock.
The array of CNC machines encompasses 3-axis, 4-axis, and 5-axis milling machines, lathes,
and routers. The approach to cutting CNC parts can differ, with scenarios involving the workpiece
staying static while the tool moves, the tool remaining in position while the workpiece is rotated
and shifted, or both the cutting tool and workpiece moving concurrently.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services encompass both milling (3-axis, 3+2-axis, and 5-axis) and turning
processes. For 3/3+2-axis CNC milling, we can machine parts with dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.).
In the case of 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
When it comes to CNC turning, we can handle parts with a maximum diameter of 431 mm (17 in.)
and a length of 990 mm (39 in.). For smaller parts, we recommend a minimum size of around
10 x 10 x 10 mm (0.39 x 0.39 x 0.39 in.).
Additionally, feature dimensions should not fall below 0.5 mm. Please note that our platform is
limited to a maximum size of 1000 mm (39 in.) for parts. If you have requirements beyond this
limit, feel free to contact our sales team for specialized assistance.
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.
