Manufacturing service provider from Stolberg near Aachen
Maschinenbau Ortmanns GmbH is a contract manufacturer for parts production based in Stolberg, in the immediate vicinity of Aachen and RWTH. The company produces products and end-to-end solutions made of metal and plastic – from individual parts and prototypes to small series. The value chain includes CNC turning and CNC milling (3+2 and 5-axis simultaneous) on modern machining centers, wire EDM for external and internal contours with high surface quality, and trowalizing (mass finishing) for deburring, edge rounding and polishing. In addition, Ortmanns offers CAD/CAM programming, design, surface treatment and assembly of ready-to-install assemblies, working as an extended workbench integrated into customers' production processes. All components are measured and documented in a climate-controlled measuring room; the company is certified to DIN EN ISO 9001. With ten employees, Ortmanns manufactures for eleven key customers from the mechanical engineering sector.

Materials and processes
CNC turning
Precision manufacturing of complex workpieces with high dimensional accuracy on modern turning centers.
CNC milling (3+2 and 5-axis)
Machining of highly complex workpieces according to drawing or 3D data in all machinable materials, machined all around simultaneously.
Wire EDM
Erosion of external and internal contours in a water bath for sharp-edged workpieces with high surface quality and tight tolerances.
Trowalizing
Gentle deburring, edge rounding, grinding, smoothing and polishing in the vibratory trough.
Brass wire (EDM wire)
Continuous wire used as a tool in wire EDM for electrical erosion.
