What Is The Process By Which The Janvier Machine Transfer The Design Of The Gold Coin Onto A Working Hub?
A Janvier, also known by the names pantograph and reducer machine, is utilized to transfer the design for a coin or medal from a master hub onto an operational hub. This is a brief overview of the Master Hub Creation.
The master hub is the first die or mold that carries the exact shape of the medal or coin. The master hub is usually made using CNC machining techniques or other techniques to ensure precision.
Janvier Machine Installation
The Janvier machine has an instrument for drawing the design onto the hub master and an aide-memoire cutter that replicates the design.
The Janvier machine has the master wheel which is linked to the machine. It serves as a model to which designs can be transferred.
Finding the design
The Janvier stylus follows the design's contours as well as the details on the master hub. The stylus tracks the shape of the design when it travels across the hub's surface.
The reduction of design-related
The Janvier machine simultaneously copies the design that was traced out onto the work hub. This is usually made from softer materials than the master wheel, for example, steel or nickel.
The cutting tool reduces or transfers the design onto the hub of the wheel in a smaller size or scale in comparison to the hub that is the master hub. This reduces the possibility of striking coins and medals in the desired size.
Accuracy and Precision
Janvier machines are operated with a high degree of precision to ensure a perfect transfer of design from master hub to working hub. The machine is able to reproduce even the most minute details and contours.
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's working hub is used to create coins or medals. It is used to create multiple blanks of the coin or medal with the design transferred.
The Janvier machine's function is vital for the minting process which allows for the reproduction and reduction of intricate coin or medal designs from master hubs to working hubs accurately. These hubs will be utilized to mass produce coins or other medals by striking the process.
