Braillon Magnetics, an app to check magnetic clamping
Braillon has made magnetic chucks since 1921. We took over its Windows calculation software and turned it into a clear mobile app for machinists.
- The need
- Before machining a part on a magnetic chuck, you need to know whether the clamping force will hold against the cutting force. Braillon had Windows software for this, accurate but ageing and impractical on the shop floor.
- What we built
- A five-step calculation, part, material, chuck, tool, then the simulation
- 19 material grades and 6 tool types
- A clear verdict comparing clamping force with cutting force
- Saved simulations and imperial units
- Four languages and Braillon’s technical documentation built in
- An app that works with no network and no server
- How we worked
- The original calculation engine was written in C#. We ported it exactly, keeping every coefficient and even the way .NET rounds numbers, to get exactly the same results as the original software. On top, we designed a step-by-step interface that makes complex engineering concepts easy to use.
- Technologies
- React Native
- TypeScript
- NativeWind
- React Navigation
- The result
- Results match the original software exactly, with extra safeguards added after feedback from Braillon’s teams in 2026. Machinists now have the calculation in their pocket, right next to the machine.
