CNC machining operates through subtractive processes, wherein the feedstock is machined to its
final form by the removal of material. This involves drilling holes, boring lots and pathways, and
shaping metal stock into new material with varying tapers, diameters, and shapes.
In subtractive manufacturing, the achievement of shapes relies on the removal of material,
a distinctive feature when compared to additive manufacturing methods that involve the addition,
layering, and deformation of materials to achieve a specified shape.
It also contrasts with injection molding, where material is injected in a different state of matter
using a mold and formed to a predetermined shape.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services cover a range of processes, including milling (3-axis, 3+2-axis, and
5-axis) and turning. In 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.).
For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
CNC turning allows for a maximum diameter of 431 mm (17 in.) and a length of 990 mm (39 in.).
When considering smaller parts, we recommend a minimum size of around 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), with feature dimensions not going below 0.5 mm.
It's important to note that our platform has a maximum part size limitation of 1000 mm (39 in.).
For larger requirements, please reach out to our sales team for personalized assistance.
2. What cosmetic standards do you guarantee?
Ensuring high-quality finishes, all CNC machined parts undergo standard deburring and
edge-breaking procedures. Critical edges requiring a sharp finish must be explicitly highlighted
in technical drawings.
Surfaces are guaranteed to be free from defects such as scratches, dents, stains, blemishes,
hanging marks, and minor imperfections. Specifically, critical surfaces (primary (a) side, per
technical drawings) will be devoid of mill steps and other marks. On the secondary (b) side,
minor hanging marks and up to 2 minor defects are considered acceptable.
To further enhance surface quality, visual appeal, and wear resistance, a variety of post-processing
and finishing methods can be applied to CNC machined parts.
3. How much does CNC machining cost?
The cost of CNC machining hinges on factors such as complexity, quantity, and lead time.
For an accurate cost estimate, we recommend submitting a 3D CAD model to receive an
interactive quote along with design for manufacturability (DFM) feedback.
Thanks to our proprietary software and automated fixturing processes, upfront non-recurring
engineering (NRE) costs are eliminated. This makes CNC machining economically viable for
quantities ranging from 1 to 200 parts. While prices may align or slightly exceed those of 3D
printing, CNC machining offers superior material properties and surface finishes.
