Bumotec s181

Mill-turn machining center from bar stock

With more than 10 years of experience acquired on our s191 model, the benchmark on the market, Bumotec launches the new series of s181, which combines the best of Swiss made know-how and a high degree of innovation.
With twin machining stations , a milling spindle capable to reach up to 40’000 rpm’s and a high availability of tooling in the automatic tool magazine, Bumotec s181 has the capability to produce complex components from bar stock up to 32 mm diameter.
The machine mineral casting bed, the latest CNC technology and the linear motor drives ensure uncompromised thermic stability and performances.
Suitable for Watch, surgical instruments, medical implants and complex micro-mechanical components, the s181 is a major asset to help you to take on the actual and future industry challenges.
