How Can A Janvier Transfer The Gold-Colored Design Of A Coin Medal From The Master Hub Into An Operational Hub?
The Janvier machine (also known as pantographs, or reducing machines) is a specific device that allows the transfer of the design of a medal or coin from the master hub onto the working hub. Here's a brief overview of how it works. Master Hub Creation-
The master hub is actually the die or mold, that contains the exact design for the medal or coin. It is made through CNC machining, or using other precision techniques.
Janvier Machine Installation and Setup
The Janvier machine has an instrument for drawing the design on the hub master, and a cutter that reproduces the pattern.
The Janvier machine is equipped with a master hub, which serves as a template for the transfer of the design.
Tracing Design
The Janvier machine has a stylus that is able to follow the contours, details and shape of the master wheel. The stylus on the Janvier machine captures its profile as it moves along the surface.
Reduce the Design
In parallel, the cutting tool of the Janvier machine copies the design traced onto the hub that is working, which is usually comprised of softer material than the master hub, such as nickel or steel.
The cutting tool reduces or replicates the design on the hub of the wheel, but at a lower size or scale in comparison to the master hub. This reduction is essential for the process of coining because it permits medals or coins to be made at the sizes desired.
Precision and Accuracy
Janvier’s machine works with precision and ensures a perfect transfer of design information from the master to the working hub. It is able to reproduce even the smallest details and contours.
Quality Control
Quality checks and inspections are carried out to ensure that the design is in line with the specifications and accuracy required for the process of striking.
Further Processing
The Janvier machine creates a working hub that is used in the coin and medal making process. It functions as a mold or die for multiple coins or medals blanks that have the transferred design.
Janvier's machine plays a crucial role for coining. It allows for the exact replication and reduction from a master to working hubs of complex designs. These working hubs are then used in the production of medals or coins by means of the striking process.
