How Does A Janvier Transfer The Gold-Colored Design Of A Gold Coin Or Medal From The Master Hub Into An Operational Hub?
The Janvier machine (also called pantographs or reduction machines) is a unique device that transfers an image of a coin or medal from the master hub onto the working hub. Here's an overview of how it works. Master Hub Creation-
The master hub is the first coin, medal or coin mold. It is produced using CNC machining, or using other precision techniques.
Configuration for Janvier MachineSetup for Janvier Machine
The Janvier machine includes stylus, which copy the design of the master hub to the working hub.
The Janvier machine has the master wheel which is linked to the machine. It functions as a model from which designs can be transferred.
Tracing Design
The stylus on the Janvier machine tracks the contours and fine details of the design on the master hub. As the stylus moves across the surface of the hub master, it records the design's profile.
Reduce the Design
The Janvier machine simultaneously copies the traced-out design onto the hub for work. This is usually made of softer materials than the master wheel, for example, steel or nickel.
The cutting tool reduces or duplicates the design onto the working hub on the smaller or smaller size compared to the master hub. The smaller size is crucial in the making of medals and coins which allows them to be struck at the right dimensions.
Accuracy and precision
Janvier machines are controlled with precision in order to ensure a perfect transfer of designs from the master hub to the operating hub. It precisely reproduces every detail and curves, including the smallest of them.
Quality Control-
The final working hub goes through quality checks to ensure it conforms to the specifications for striking and is accurate.
More Processing
The working hub that is created by the Janvier machine is used to aid in the coin or medal striking process. It serves as a mold or a die to create multiple medals or coins that are blank and have the design transferred.
Janvier machines are essential for the production of coins and medals. They allow the precise reproduction of intricate coin or badge designs. These working centers are then utilized to make large quantities of coins and medals with the strike method.
