If you have two components that are friction fit together, where the first one is very soft and other very hard and rigid, how do you calculate a tolerance band for that fit? Well, any theoretical calculation is still only a ‘best guess’ – until the components are machined, decorated and finally fitted together.
Practically, what is the ‘correct size hole’ for the incabloc assembly? And most importantly, at what diameter is that hole either too large or too small? This is the kind of information that Swiss watchmakers are not going to tell you, so you have to figure that out by yourself. And even if they would be prepared to disclose their best kept secret, they couldn’t- because none of them use tricomponent Titanium alloy to manufacture watch main plates.
I am very pleased to share some good news: at this point in time we have reached another milestone in our ‘manufactured in Australia’ project. It is based on the following:
- ability to ‘read’ DNA of this rather delicate assembly
- measure existing components fast and compare results automatically,
- design and machine test pieces in Timascus, re-measure them at sub-micron level,
- then create numerous variations of the same feature in diameter steps of 2 microns,
- friction assembly of components
- investigate deformation of ‘soft’ incabloc housing
- find the tolerance band
- to manufacture multiple main plates, while keeping the tolerances consistently within the band.
