Line Card
Swiss Automation is one of the largest precision Swiss screw machine houses in the United States, with over 180 CNC Swiss-type machines on the floor running 24/7. Engineers and procurement teams at medical device, aerospace, firearms, and industrial companies work with Swiss Automation when they need tight-tolerance turned components with consistent lot-to-lot repeatability and full ISO 13485 documentation support.
The facility runs Citizen, Tornos-Bechler DECO, Star, Miyano, Hardinge, and Eurotech Swiss machines — many with up to 12 axes of cutting capability and dual-spindle configuration. That equipment depth means complex geometries, cross holes, thread whirling, and milled features are handled in a single setup, reducing lead time and eliminating transfer risk.
