The master hub is the first mold or die that contains the exact layout of the coin or medal. It's made with high-quality CNC manufacturing.
Installation for Janvier MachineSetup for Janvier Machine
The Janvier machine consists of a stylus that trace the design on the master hub, and a cutting tool that replicates the design on the working hub.
The hub master is securely placed on the Janvier machine, serving as a template upon where the design can be transferred.
Tracing Design-
The stylus on the Janvier machine follows the contours and details of the design that is on the hub master. When the stylus travels across the surface, it record the design's profile.
Reduce the Design
Simultaneously on the Janvier, the cutting tool copies the designs traced onto the machine's hub which is normally constructed from an abrasive material such as steel or nickel.
The cutting tool reduces, or copies the design to the working hub in a smaller or reduced dimension compared to the master hub. This allows the cutting tool to create coins and medals that are the desired size.
Precision and Accuracy-
Janvier machines are operated with precision in order to ensure the exact transfer of design from the master hub to the operating hub. It replicates every detail and contour with precision.
Quality Control
Inspections and quality checks are carried out to ensure that the design is in line with the requirements and accuracy needed for the striking process.
