What Is The Process By Which The Janvier Machine Transfer The Gold Coin Or Medal Design To The Hub Of The Master?
A Janvier machine is also known as pantograph, also known as a reduction machine. It's used to transfer the designs of a coin or medal from the master to a working center. The Master Hub Creation is explained in this video.
The master hub is the original mold or die that contains the exact design of the coin or medal. It is usually made using CNC machining or other precision methods to guarantee accuracy.
Janvier Machine - Installation and Setup
The Janvier Machine consists of two elements which include a stylus that trace the design, and a tool that cuts the design.
The Janvier machine is fitted with a master hub which acts as a template to guide the transfer of design.
Finding the Design
The Janvier machine uses a stylus to follow the contours and detail of the design. When the stylus is moved across the surface, it captures the design's outline.
Reducing Design-
The Janvier machine can also reproduce the pattern traced onto the hub that is in use. The hub is usually constructed from a soft material, such as nickel or steel, as opposed to the hub that is used as the master hub.
The cutting device reduces or transfers the design onto the hub of the wheel, but at a lower scale or size in comparison to the master hub. This reduction allows for striking coins and medals that are the desired size.
Accuracy and Precision
Janvier's machine is precise and ensures the perfect transfer of design information from the master to the working hub. It reproduces with precision all the details and contours, even the smallest of them.
Quality Control
The resulting working hub is subject to quality inspections and inspection to ensure that the design is in line with the specifications and precision required for the process of striking.
Further Processing
The Janvier working hub is an instrument to facilitate the process of striking medals or coins. It acts as a mold or die that is used to make multiple blanks for medals or coins with the transfer design.
Janvier is an essential element in minting because it has the ability to precisely replicate and reduce complex designs of medals or coins. These working hubs are then used for the mass production of medals or coins by means of the striking process.
