Frequently Asked Questions
What is CNC milling?
CNC milling is a subtractive process where rotating multi-point cutting tools remove material from a workpiece under computer control to produce precise prismatic parts, slots, pockets, holes, and complex 3D surfaces.
What materials can you CNC mill?
We mill aluminum, stainless steel, mild and alloy steel, brass, copper, titanium, and engineering plastics such as ABS, POM (Delrin), nylon, PC, PMMA, and PEEK.
What tolerances can CNC milling hold?
Standard tolerance is ISO 2768-m (±0.1 mm). With precision setups and in-process inspection we hold tighter tolerances down to ±0.01 mm on critical features.
What is the difference between 3-axis and 5-axis milling?
3-axis milling moves the tool in X, Y, and Z. 5-axis adds two rotary axes, letting us machine complex geometries and undercuts in a single setup with better accuracy and surface finish.
What surface finishes are available for milled parts?
As-machined, bead blasting, anodizing, powder coating, electroplating, brushing, polishing, and painting. Tell us the Ra or cosmetic requirement and we will advise.
What is the maximum part size you can mill?
Typical envelope is up to about 800 × 500 × 300 mm per part; larger parts can be quoted on request. Minimum wall thickness is around 0.5 mm depending on material.
What is the lead time for CNC milled parts?
Prototypes ship in as fast as 3–5 business days; low-volume production typically 7–15 days depending on quantity, material, and finishing.
How do I get a quote for CNC milling?
Upload your STEP, IGES, or X_T file (plus a 2D drawing for tolerances) on our Request a Quote page and our engineers return a DFM review and price.
