Product Overview
CNC milling removes material from a workpiece using computer controlled machine tools, which makes it the practical route for prismatic parts with features on several faces. Parts are milled in aluminium, brass and other materials, with turning available where a component has round features as well. Precision and repeatability are the reasons milling is used for complex parts across industry.
Key Benefits
- Features on several faces produced in a controlled sequence
- Repeatability across a production batch once the programme is proven
- Aluminium, brass and other materials to the same drawing
- Turning available for parts that combine round and prismatic features
- Complex geometry produced without special tooling
Problems It Solves
- Positional tolerance lost between features machined in separate operations
- Parts too complex to produce by fabrication
- Prototypes that cannot be reproduced consistently in volume
- Tooling cost that cannot be justified at the quantity required
Where It Is Used
Applications And Buyers
Application Scenarios
- Housings and manifolds with machined faces and bores
- Brackets and mounting plates with tight positional tolerance
- Equipment components with pockets, slots and threaded holes
- Prototype parts before a production process is chosen
Who It Is For
- Machine and equipment builders
- Product developers needing functional prototypes
- Manufacturers replacing fabricated parts with machined ones
- Buyers who need the same part repeated batch after batch

Customisation Options
What Can Be Varied
- Parts machined from your drawing or 3D model
- Material grade agreed before production
- Tolerances set per feature
- Surface finish and deburring level
- Prototype quantities followed by production batches
Compared With The Alternatives
| CNC turning parts | Turning is better and cheaper for round parts; milling is the answer when the part is prismatic or has features on several faces. |
|---|---|
| Casting | Casting is cheaper at high volume but needs tooling and leaves machining allowances; milling from solid suits lower volumes and design changes. |
Use Guide
- Send a 3D model so tool access can be checked before quoting
- Specify internal corner radii, since they decide the smallest cutter that can be used
- Mark datums clearly so the part is fixtured the way it is measured
- Order prototypes in the production material to avoid surprises later
Questions
Questions Buyers Ask About This Product
What kinds of parts suit CNC milling?
Prismatic parts with pockets, slots, faces and bores, especially where features must relate accurately across several faces.
Which materials do you mill?
Aluminium, brass and other materials on request.
Can you mill and turn the same part?
Yes, turning is used alongside milling where a component has round features.
Do you take prototype orders?
Yes, and we recommend prototyping in the production material so results carry over.
How consistent are repeat batches?
Once the programme and fixturing are proven, repeat batches are produced from the same set up and inspected against the same drawing.
