CNC Milling FAQ

To assist you in your design and planning process, we've compiled answers to some of the most common technical questions we receive about our CNC milling services. If you have a question that is not answered here, our engineering team is always ready to help.

What's the difference between 3-axis and 4-axis milling?

3-axis milling operates on the X, Y, and Z axes. 4-axis adds rotation around the X-axis, allowing for machining on the sides of a part without new setups, which improves accuracy and efficiency.

What is your typical internal corner radius for milled pockets?

This depends on the tool size and pocket depth, but we can typically achieve internal radii as small as 0.5mm. Please note this on your drawing if it's a critical feature.

Can you mill high-temperature plastics like PEEK?

Yes, we have extensive experience milling high-performance plastics, including PEEK, PEI (Ultem), and PPS. We use specialized tooling and techniques to manage heat and ensure dimensional stability.

What is the minimum wall thickness you can machine?

We recommend a minimum wall thickness of 1mm for metals and 1.5mm for plastics. Thinner walls are possible depending on material and part geometry, so please note it on your drawing for our DfM review.

What are the main cost drivers in CNC milling?

The main cost drivers are Machining Time, Material Cost, Number of Setups, and the complexity and tightness of Tolerances.

How should I specify the required surface finish on my drawing?

Please specify the required surface finish using the Ra value (e.g., Ra 1.6 μm) on your drawing. Our standard as-milled finish is Ra 3.2 μm, but finer finishes are available upon request.
