The stylus of the Janvier machine follows the contours and details of the design that is on the master hub. As the stylus moves along the surface of the hub master, it records the design's profile.
Reduce the Design-
The Janvier machine simultaneously copies the drawn-out design onto the hub for work. This is usually constructed with softer components than the master wheel like steel or nickel.
The cutting tool reduces, or duplicates the design to the working hub in a smaller or reduced size compared to the hub that is master. This allows the cutting tool to create coins and medals in the size you want.
Accuracy and Precision
Janvier machines are operated with a high degree of precision to ensure a perfect transfer of design from master hub to working hub. It faithfully recreates the tiny details and contours.
