About Cavelti Mechanik AG
Cavelti Mechanik AG is a contract manufacturer specialized in turning and turn-milling of custom precision parts in series production, based in Domat/Ems in the canton of Graubünden, Switzerland. Complex parts are produced in a single operation on NAKAMURA TOME multi-tasking turn-mill centers with 7 axes, 2 spindles and 2 turrets each, as well as on a STAR Swiss-type lathe; the machine park is equipped with automation for 24/7 operation. The material range includes stainless steel, steel, brass, titanium, aluminium, plastics and nickel-based alloys. In addition to CNC machining, the company offers design and material consulting, assembly of assemblies, vibratory finishing, laser marking with a fiber laser, and part cleaning. Quality assurance is performed with 3D coordinate measurement, optical measuring systems and surface measurement; the company is certified to ISO 9001:2015 and holds a re-stamping approval under AD 2000-HP 0 / SVTI.
