Machines for Watchmakers
The Model B Bobineau introduces advanced kinematic control over workpiece rotation, making it the ideal tool for repetitive geometric operations and calibrated faceting on watch bezels and cases. Compared to Model A, it integrates a **mechanical indexing** system that transforms free rotation into a controlled and lockable angular movement, ideal for those requiring absolute consistency in polygonal or symmetrical finishes on a lapidary machine. **The 360° rotation is fully lockable** and micrometrically adjustable. This allows for precise angular divisions to achieve uniform faceting, interrupted beveling, and perfect geometric decorations. **The 3-jaw self-centering workpiece holder** head is integrated directly onto the spindle to ensure maximum structural rigidity and eliminate any micro-play during operations under load. **Horizontal axis: "lock and release"** type angle adjustment for quick orientation. **Vertical axis: advanced micrometric adjustment** for a millimeter-accurate inclination setup relative to the lapping disc. Detachable body from the base: retains the modularity of the upper body, which can be easily removed from the lower bearing-supported base using the specific handle for manual finishing operations on a buffing machine. Equipped with bronze or nylon jaws, with shapes optimized for haute horlogerie profiles. A custom jaw manufacturing service is available on demand.
