Technology mix in perfection –
just one of our strengths
With around 100 CNC processing machines we primarily manufacture midsize series up to fully automated large scales with daily volumes of more than 25.000 pieces.
Our particular strengths are complex turning-, drilling-, grinding and milling operations of all kinds of metallic materials with narrow tolerances up to the IT6 range. We manufacture our components in several value added stages with appropriate deburring (i.a. ECM).
Since the cleanliness of our products plays an increasingly important role for our customers, we have also focused on provision and conformity with strict residual dirt specifications. We therefore, among other things, have the most advanced washing technology (also with high pressure) and appropriate equipment to determine residual dirt.

Deburring
- Electrochemical deburring (ECM)
- Pulse-ECM
- High-pressure deburring (HD)
- Barrel finishing
- Thermal deburring (TEM)
- Integrated in the manufacturing process: brushing, high-pressure rinsing
Cleaning
- Aqueous immersion bath systems with multilevel ultrasonic- and flood washing
- Aqueous chamber washing systems with ultrasonic washing and pressure flooding
- High-pressure washing systems (up to 700 bar)
Cleanliness requirements:
- Particle size: ≤ 200µm
- Residual dirt ≤ 0,5 mg / piece
- High-pressure washing systems (up to 700 bar)
At our plant for the residual dirt analysis the evaluation of technical cleanliness is done by particle size (pattern perception) and particle weight (weigh out), according to VDA19.
