questions

Everything you need to know about our grinding service.

Surface grinding, plus external and internal cylindrical grinding. For hardened, case-hardened or nitrided parts.

We achieve finishes of Ra 0.2 μm or better, depending on the material and the geometry of the part.

Yes, it is one of our specialities. We grind materials up to 65 HRC without difficulty.

Our grinding machines accept parts up to 500mm for cylindrical grinding and 600×300mm for surface grinding.

Yes, we offer an urgent 24-48 hour service for critical parts that need immediate grinding.

Yes, we supply measurement reports produced with calibrated instruments and full metrological traceability.
