How Does The Janvier Machine Transfer Gold Coins Or Medals From Master Hubs To The Working Hub?
A Janvier is also known under the terms pantograph and reducing machine, can be employed to transfer designs for a coin or medal from a master hub onto a working hub. Here is a quick overview of the Master Hub Creation.
The master hub is the primary mold or die that contains the exact layout of the medal or coin. It is usually made using CNC machining or other precision methods to ensure precision.
Janvier Machine Installation
The Janvier machine comes with stylus that copies the design from the master hub onto the one that is working.
The Janvier machine comes with a master hub that acts as a template to guide the transfer of the design.
The design is traced
The Janvier stylus in the machine captures the contour of the design while it travels along the surface of the master hub. As the stylus moves across the surface of master hub it tracks its contours.
Reduce the Design
Simultaneously the Janvier cutting tool of the machine transfers the design traced on to the hub in use. The hub is constructed from a less hard metal than the master, usually steel or nickel.
The cutting instruments reduce or duplicate the design at the smaller scale or at a smaller size, compared to master hub. This reduces the possibility of striking coins and medals in the desired size.
Precision and Accuracy
Janvier's machine operates precisely, ensuring an accurate transfer from the master hub to the hub for operation. It replicates even the smallest details and contours precisely.
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.
Additional Processing
The Janvier machine's hub of working is used to strike coins or medals. It's used as a mold, or die to create multiple medals or coins that are blank and have the transferred design.
The Janvier machine's role is crucial for the minting process which allows for the reproduction and reduction of intricate medal designs from master hubs to working hubs with precision. The working hubs are used for the mass production of medals and coins by means of the striking process.
