About 1AMechanics
1AMechanics GmbH, based in Pratteln in the canton of Basel-Landschaft, is a machining company specialized in mechanical manufacturing. Its core competence is vertical slotting: on two Ravensburg slotting machines, the company produces keyways, keyways to DIN 6885, keyway hub profiles (DIN-ISO 14, DIN 5463, DIN 5464, DIN 5471, DIN 5472, BSA20), involute spline hub profiles (DIN 5480, DIN 5481, DIN 5482), external slotting such as ratchets, as well as internal hexagons and internal N-edges – also on workpieces with large widths and lengths or blind holes. In addition, CNC turning and CNC milling are available on two MORI SEIKI turn-mill centers and one conventional lead-screw lathe, from one-off pieces to series production. An in-house tool grinding machine allows the manufacture and adaptation of slotting tools, including carbide. Through vetted partner companies, the company offers complete machining including turning, milling and grinding with its own planning and supervision. In engineering, the range extends from drawing creation to the design of complete gearbox assemblies including gear calculations, among other things for vintage vehicles, industrial plants and spare parts for machine tools.
