What Is The Process By Which The Janvier Machine Transfer The Gold Coin Or Medal Design To The Working Hub Of The Master?
A Janvier is also known by the name pantograph or reduction machine, is employed to transfer designs for a coin or medal from a master hub onto the hub that is working. Here's an overview of the process it uses to accomplish this Master Hub Creation-
The master hub is the primary coin, medal or coin mold. To ensure accuracy the hub is usually made using CNC machineries and other high-precision techniques.
Janvier Machine Installation
The Janvier machine consists of a stylus that traces the design onto the master hub, and a cutting device that copies this design to the hub that is in use.
The Janvier machine's master hub, which serves as a model from which the design can be re-created, is hung securely on the machine.
The design is traced
The Janvier machine has a stylus that is able to follow the contours, details and the design of the master wheel. When the stylus is moved on the surface of master hub it tracks its contours.
Reduce the Design
The Janvier machine simultaneously copies the design that was traced out onto the work hub. This is usually constructed from softer materials as opposed to the master wheel such as nickel or steel.
The cutting tool reduces, or copies the design to the hub that is working at a reduced or smaller size compared to the hub that is master. This reduces the possibility of striking coins and medals in the size you want.
Accuracy and precision
The Janvier machine is operated precisely to ensure an exact transfer of the design from the master hub to the working hub. It reproduces even the tiniest details and contours faithfully.
Quality Control
Quality checks and inspections are conducted to confirm that the design used is compatible with the specifications and accuracy required for the process of striking.
More Processing
The working hub created by the Janvier machine can be used to aid in the coin or medal striking process. It is used as a mold or die to create a variety of blank coins or medals with the transfered design.
The Janvier machine plays an important part in the production process, as it allows the exact replication and resizing of intricate designs on coins or medals from a hub that is working to a master hub. These hubs then are utilized in the mass production of medals and coins through the striking process.
