What Is The Process By Which An Janvier Machine Transfer Gold Coins Or Medals Design To The Working Hub Of The Master?
A Janvier machine is also called pantograph, also known as a reduction machine. It's employed to transfer the appearance of a coin medal from a master to a working center. This is a brief description of this Master Hub Creation.
The master die is the primary mould or die which contains the exact design of the coin. The master hub is usually made by using CNC machines or other precision methods to ensure precision.
Configuration for Janvier Machine-
The Janvier machine has an instrument to trace the design on the hub master as well as a cutter that reproduces the design.
The master hub is securely fixed to the Janvier machine, serving as a template upon where the design can be transferred.
A Design is traced
The Janvier machine employs a stylus to follow the contours and detail of the design. The Janvier machine's stylus keeps track of the shape of the surface when it moves on the surface.
Reduce the DesignReducing the Design
In tandem with the Janvier, the cutting tool replicates the traced designs onto the central hub of the machine, which is usually composed of steel, a soft metal or Nickel.
The cutting tool cuts or reproduces the design on the working hub on the smaller or smaller dimensions compared to the hub that is used as the master hub. This reduction is vital to the process of minting, since it allows for the striking of medals or coins at the desired size.
Accuracy and Precision
Janvier is a precision machine that guarantees a precise transfer of design from the master hub to the hub that is in use. It recreates every single detail and contour with accuracy.
Quality Control
The hub's working part will be subjected to inspection and quality control to ensure it matches the required specifications and accuracy in the process of striking.
Further Processing
The Janvier machine makes a functional hub for the coin and medal striking process. The mold or die is used to create multiple medal or coin blanks by using the transfer design.
Janvier machines are crucial to the production of medals and coins. They allow the precise replication of intricate coin or badge designs. The working hubs can be used to produce mass quantities of coins or other medals by using the striking process.
