Machine Fabrication Service
Our CNC machining capabilities cover the spectrum, allowing us to fabricate parts of varying
complexities, from straightforward "as machined" workholdings to intricate geometries.
Operating an extensive array of CNC mills and turning centers, we can also incorporate EDM and
grinders based on your requirements. Precision is our hallmark, with tolerances reaching as low as
0.05 mm (0.0020 in), and our efficient processes ensure lead times starting at just one business day.
Product Details
CNC machining materials are generally grouped into three primary categories: plastics, soft metals,
and hard metals. This classification includes materials such as aluminum, bronze, copper, ceramics,
plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.

CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design complexity,
the number and size of features, materials used, surface finish, and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production time and cost.
CNC Milling Tolerances | ||
Limits for nominal size | Plastics | Metals |
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
Over 6mm to 30mm | ±0.2mm | ±0.10mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 120mm to 400mm | ±0.5mm | ±0.20mm |
Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes, below 0.5mm on your technical drawing. |
Specialist industries

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. Factors Influencing CNC Machining Costs:
The cost of CNC machining a part is influenced by several key factors, including:
1. Material: Variations in material costs arise as some materials, such as aluminum, are more
cost-effective to machine than others like Inconel due to increased tool wear and slower cutting
speeds.
2. Complexity: Parts with intricate features incur higher machining costs. Complex surface shapes,
for instance, are notably more expensive to machine compared to flat surfaces.
3. Tolerances: Stringent dimensional tolerances escalate machining costs. Specifying unnecessarily
tight tolerances on non-critical features can contribute to increased CNC machining expenses.
4. Surface Finish: Achieving mirror finishes necessitates specialized tooling and machining strategies,
extending machining time and subsequently increasing costs.
5. Quantity: Low-volume production inherently comes at a higher cost per part than large-volume
production. This is because initial setup and programming costs are distributed over a greater number
of parts in large-volume production.
