High-precision CNC-milled parts made from aluminium, stainless steel, brass or plastic. Manufactured to CAD specifications, prototypes and series.
CNC-milled parts are indispensable in industry, mechanical engineering and technical manufacturing. With state-of-the-art, computer-controlled milling machines, workpieces made of aluminium, stainless steel, brass, plastics or composite materials can be produced with high precision and efficiency. They enable dimensionally accurate geometries, complex contours, exact holes and the finest surface structures. This is decisive in particular for projects with micrometre tolerances, demanding functional parts or prototypes. Our range of services covers the production of individual components, prototypes and series, including individual adjustments, special solutions and complex functional components.
What are CNC-milled parts?
CNC-milled parts are highly precisely manufactured components that are machined from a raw material by computer-aided milling machines (CNC machines). These components can comprise both simple flat parts and complex three-dimensional structures, which are distinguished by their high dimensional accuracy and attention to detail. The manufacturing process follows exact CAD specifications, with the machines moving the workpiece and tool in several axes in order to produce exact cuts, holes, grooves and contours.
It is particularly important that CNC-milled parts are suitable both for one-off production and for series production. They make it possible to realise complex geometries that would be difficult or even impossible to implement with conventional manufacturing methods. In addition, they enable optimisation of material use, reduce scrap and rework and ensure consistent quality across the entire production batch. CNC-milled parts thus form the basis for highly precise machines, devices and industrial applications that require exact dimensions, repeatable functionality and reliable performance.
Materials and substances
We process a broad range of materials, matched to the requirements of your project:
| Material | Properties | Typical applications |
|---|---|---|
| Aluminium | Light, corrosion-resistant, versatile | Mechanical engineering, vehicle construction, architecture, prototypes |
| Stainless steel | Robust, corrosion- and heat-resistant | Food technology, medical technology, chemical plants |
| Brass/copper | Good conductivity, malleable | Connectors, bearings, decorative components |
| Plastics (POM, ABS, PVC) | Light, chemically resistant compared with aluminium sheets, easy to machine | Housings, functional components, technical components |
| Composite materials | Tailor-made, vibration-damping, insulating | Lightweight construction, special applications, high-performance components |
In addition, we take into account temperature resistance of aluminium sheets, friction behaviour, corrosion protection, electrical conductivity and mechanical load capacity in order to ensure the service life and functionality of the components optimally. For special applications, we also examine material properties such as impact strength, vibration damping or chemical resistance. This enables precise adaptation to specific requirements, whether for extreme loads, highly precise functional components or innovative prototypes.
Manufacturing process
The manufacturing process comprises several precise steps that ensure maximum quality. First, the detailed planning and checking of the CAD data takes place. Drawings and 3D models are analysed, milling paths, tolerances and material requirements are defined exactly. This is followed by CNC milling on 3-, 4- or 5-axis machines, which can machine complex geometries to millimetre accuracy. Different milling strategies are used in order to minimise material stresses, prevent distortion and optimise surface quality.
Post-processing can comprise grinding, deburring, polishing, anodising of aluminium sheets, powder coating or further surface treatments. Finally, comprehensive quality control takes place: dimensional inspection, surface roughness, 3D measurement and functional tests are documented in order to ensure the highest precision and reliability.
