High quality precision

Metal chipping: since 1968. 


Contract Manufacturing

Machining of single items and series


As a contract manufacturer and expert in the machining of complex workpieces, we specialize in the production of precision parts for our clients, including, for example, the automotive and mechanical industries, as well as the plant engineering and packaging sectors.


Other than providing the geometric design for the workpieces, we efficiently integrate any required external production steps into our workflow: heat treatment, Teflon coating, and deep hole drilling are just a few examples.


This way, the workpieces can be delivered ready for assembly and, if required, fully mounted - on time and with tested quality.


Exemplary selection of sophisticated single components

Setting Gauges

In order to be able to precisely adjust the cutting edges of in-line boring bars, we develop and design sets of gauges for our clients. The gauges can be used to adjust the cutting edge with micrometer accuracy  to ensure stable series production of high-precision bores.

The setting gauges can also be used to adjust cutting edges for valve seat or piston bore machining. We have also carried out other applications, such as the insert adjustment of a jumbo milling cutter with a diameter of 2000 mm, as part of a previous project.


Testing Gauges

Mechanical measuring and testing systems

Instead of relying on complex and cost-intensive technology, we use traditional, precise, and reliable solutions on a mechanical basis - based on the customer's specifications or on customized design.


The measuring and testing devices are manufactured in our own machine park with high vertical integration. Examples include insertion gauges, checking gauges or measuring devices for workpiece inspection during production (e.g. wheel carriers in the automotive industry).

In our construction department we develop and design solutions in the field of machining and measuring technology. The technical documentation is done according to customer specification.


Furthermore, CAM programming and prototyping technologies such as 3D printing enable us to flexibly respond to the most diverse requirements.


In-house design
