CNC machining

CNC Drehen und Fräsen

Manufacturing technologies

A total of 485 CNC machines are available for turning and milling metals and plastics. These include 25 5-axis machines.

Our CNC machining centre is the solution for fast prototypes and small series production. We produce both complex prototypes and small batches of precision-manufactured parts.

Additional technologies such as thread cutting, drilling, eroding and wire cutting round off the production spectrum.

We also offer a range of other finishing options in the areas of surface technology, such as hard oxidation, passivation and chrome plating.

Processable metals

The metals that can be processed include aluminium, stainless steel, aluminium steels, bronze, brass, steel, titanium and carbon steel.

Processable plastics

Processable plastics include ABS, PC, PMMA, POM, PA, PP, PET, PVC, CPVC, PS, LDPE, HDPE, PSU, PPSU, nylon, PEEK, PEI and polycarbonates.

Tolerances

Our working methods are geared towards compliance with the ISO 2768 CNC machine standard. As a rule, the tolerances according to ISO 2768 (medium) and ISO 2768 (fine) are used. If tighter tolerances are required, a corresponding declaration in the drawings is necessary. Please contact us to discuss further options.

The following should be noted with regard to the edge finish: The corners of the component are removed in the form of a chamfer or radius as shown in the drawing provided for the job. Specify the size of the resulting chamfer or radius.

Possible component post-processing

Surface treatment after machining changes the appearance, surface roughness, hardness and chemical resistance of the manufactured parts. This not only fulfils the functional requirements, but also protects and enhances the machined parts.

The following technologies are available for processing:

Anodising, grinding and polishing, bead blasting and anodising, water plating, steam polishing, passivation, hard oxidation, powder coating, painting, chrome plating, electrophoresis, electropolishing, sandblasting, heat treatment, brushing, electroplating
