Our CNC mills, or CNC milling machines, are capable of producing parts in almost any shape,
using a variety of materials. From soft metals like aluminum to tougher metals like steel, and
even plastics such as acetal, we provide cost-effective milling services. Whether you require a
single part, a batch of prototypes, or a full production order, we have you covered.
Product Details
CNC machining machines exhibit the capability to cut a diverse range of materials, including
aluminum, bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and other
engineering materials.
This versatility makes CNC machining an ideal choice for generating prototypes in product
development. It enables precise and rapid adjustments until achieving the desired end product.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services encompass CNC milling (3-axis, 3+2-axis, and 5-axis)
as well as turning. 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.).
For CNC turning, we can handle parts with a maximum diameter of 431 mm (17 in.)
and a length of 990 mm (39 in.). Recommended minimum part dimensions are approximately
10 x 10 x 10 mm (0.39 x 0.39 x 0.39 in.), and feature dimensions should not go below 0.5 mm.
It's important to note that our platform has a limitation of a maximum part size of 1000 mm (39 in.).
If your project requires dimensions beyond this limit, please contact our sales team to discuss your
specific needs.
2. How much does CNC machining cost?
The cost of CNC machining is influenced by factors such as complexity, quantity, and lead time.
For an accurate assessment, the best approach is to submit a 3D CAD model, allowing us to provide
an interactive quote along with design for manufacturability (DFM) feedback.
Notably, our use of proprietary software and automated fixturing processes eliminates upfront
non-recurring engineering (NRE) costs. This streamlined approach makes purchasing quantities
as low as 1 to 200 parts cost-effective. While prices may be comparable to or slightly higher than
3D printing, CNC machining offers superior material properties and surface finishes.
3. What are standard machining tolerances?
The standard machining tolerance is ± 0.005" or 0.13mm, defining the acceptable range for a
dimension. If a CNC machining tool has a tolerance of ± 0.01 mm, it implies a deviation of 0.01 mm
in each cut. When accompanied by a drawing, our CNC machining service can achieve CNC parts
with tolerances as low as ± 0.0002 in.
In the absence of a drawing, all CNC parts are produced following our ISO 2768 medium standard.
Additionally, we have the capability to machine to tighter tolerances, such as ±0.025mm or ±0.001",
when an engineering drawing specifies critical features.
