The Janvier machine has stylus, which copy the design of the master hub to the working one.
The Janvier machine is equipped with a master hub mounted securely. It serves as the template to where the design is transferred.
Tracking The Design
The Janvier machine features stylus that follows the contours, details and the design of the master wheel. The Janvier machine's stylus captures its profile as it moves along the surface.
The reduction of design-related
Simultaneously, the cutting tool of the Janvier machine reproduces the pattern traced on the hub that is working which is made of softer material than the hub that is used as the master, like nickel or steel.
The cutting tool duplicates or reduces the design on the hub in a smaller size or scale compared to that of the hub that is master. This is crucial to the process of minting since it allows the striking of medals or coins at the exact size.
Precision and Accuracy-
The Janvier machine works with precision to ensure precise transfer of the layout from the master hub to the work hub. It reproduces every detail and contour with accuracy.
Quality Control-
The quality of the final hub is assessed to ensure that the design of the transfer meets the specifications needed for striking process.
Further Processing
The Janvier machine makes a functional hub that is used in the coin and medal striking process. It acts as a mold or die for creating multiple blanks for medals or coins with the transfer design.
The Janvier machine's role is crucial for the minting process it allows the reproduction and reduction of intricate medal designs from a master hub to working hubs precisely. Working Hubs are utilized to produce large quantities of coins or medals through the striking procedure.
