Perfect precision

STC is your expert in high-precision, metal-cutting machining with defined and undefined cutting edges. We machine and manufacture metal components and complex assemblies on over 4,500 m² of production space. As individual parts or serial parts. Depending on the requirements.


Do you want a top-notch product?

We will saw, turn, mill, grind, lap, measure and assemble components for you in series production or as individual items, with tolerances of up to 0.001 mm. Our specialty is machining with defined and undefined cutting edges. After machining we are deburring manually using microscopes for especially challenging components.


An example for our high-precision work

For the components we use in pump manufacturing, we create surfaces that make it possible to do without gaskets completely. We can create tight metal-to-metal leak tightness!
