Milled Parts to Drawing
CNC milled parts from aluminium, steel, stainless steel and plastic. 3-axis and 5-axis machining — tolerances down to ±0.01 mm.
What are CNC Milled Parts?
CNC milled parts are precision-manufactured components machined from a solid block using computer-controlled milling machines. The cutting tool rotates at high speed while the workpiece remains fixed — unlike turning, where the workpiece rotates.
The process starts with CAD design data that is converted into machine commands via CAM software. This produces even highly complex geometries with tight tolerances and excellent repeatability — from single parts to large series.
3-Axis vs. 5-Axis Milling
Depending on component complexity, we use the optimal milling process — from economical 3-axis machining to simultaneous 5-axis milling.
| Feature | 3-Axis | 3+2-Axis | 5-Axis Simultaneous |
|---|---|---|---|
| Axes | X, Y, Z linear | X, Y, Z + indexed | X, Y, Z + A, B simultaneous |
| Geometries | Flat surfaces, pockets, hole patterns | Angled machining, multiple sides | Free-form surfaces, undercuts, turbine blades |
| Setups | Multiple re-clamping | Fewer re-clampings | Single setup |
| Tolerances | ±0.05 mm | ±0.02 mm | ±0.01 mm |
| Cost efficiency | Very cost-effective | Good value for money | Optimal for complex parts |

Frequently Asked Questions about CNC Milled Parts
How much do CNC milled parts cost?
The price depends on size, material, complexity and batch size. We calculate transparently and provide a binding quotation within 24 hours.
What file formats do you accept?
We prefer STEP (.stp), IGES (.igs) and 3D-PDF. DXF, DWG and native CAD formats (SolidWorks, Inventor, Catia) can also be processed. For 2D drawings, we accept PDF with dimensions.
When do I need 5-axis milling instead of 3-axis?
5-axis milling is necessary for: free-form surfaces, undercuts, machining more than 3 sides, or when tight tolerances require machining in a single setup. For flat 2D contours and simple pockets, 3-axis milling is sufficient.
Can milled parts also include turning operations?
Yes — for parts with both prismatic and rotationally symmetric features, we combine milling and turning. Typical examples: flanges with hole patterns, housings with cylindrical bores.
How large can milled parts be?
Our maximum travel range is 700 × 560 × 510 mm (X × Y × Z). For larger parts, we are happy to discuss individual solutions, e.g. through partner companies.
What is the difference between 3+2-axis and 5-axis simultaneous?
With 3+2-axis, the rotary axes are positioned and then locked before milling — the actual machining is 3-axis. With 5-axis simultaneous, all 5 axes move at the same time, enabling true free-form surfaces and complex contours.
What surface treatments do you offer?
We offer anodising, hard coat, zinc plating, electroless nickel plating, hardening, nitriding, grinding, polishing and blasting. The choice depends on material, application and desired aesthetics.
Can aluminium milled parts be anodised?
Yes — we anodise in various colours (natural, black, red, blue) and also offer hard coat (hard anodising) for particularly stressed surfaces. The anodised layer protects against corrosion and wear.
How quickly can you deliver CNC milled parts?
Standard delivery time is 10–15 working days depending on complexity. Express production from 5 working days is available by arrangement. For series orders, we agree on individual delivery schedules.
Do you also offer contract milling / contract manufacturing?
Yes — we offer contract manufacturing on our CNC machining centres. You supply the material, we handle the machining according to your drawings and specifications.
