What Is The Process By Which A Janvier Machine Transfer The Gold Coin Or Medal Design From The Master Hub To A Working Hub?
A Janvier Machine, sometimes known as pantograph machine, or reducing device is a tool employed in the process of coining to move designs from a Master Hub to a Working Hub. This article will explain how it works. Master Hub Creation-
The master hub is the original die, or mold, that contains the exact layout for the medal or coin. The master hub is usually produced using CNC machines or other techniques to ensure precision.
Configuration for Janvier MachineSetup for Janvier Machine
The Janvier machine is comprised of a stylus that trace the design on the master hub as well as a cutting tool that replicates the same design onto the operating hub.
The Janvier machine includes a master wheel linked to the machine. It is used as a model from which designs can be transferred.
Tracing Design-
The Janvier stylus in the machine captures the contour of the design when it moves along the surface of the master hub. As the stylus moves on the surface of master hub it tracks its contours.
Reduced Design-
Simultaneously the Janvier cutting tool of the machine transfers the design traced on to the hub in use. The hub is composed from a less hard metal that the master which is typically nickel or steel.
The cutting tool cuts, or duplicates the design to the hub that is working at a reduced or smaller scale as compared with the master hub. This is crucial for the process of coining because it permits medals or coins to be made at the sizes desired.
Precision and Accuracy
Janvier is a precision machine that assures a perfect transfer of designs from the master hub onto the working hub. It recreates every single aspect and contour accurately.
Quality Control
The design and quality of the hub is checked to ensure that the design of the transfer is in line with the requirements for striking processes.
More Processing
The working hub created by the Janvier machine can be used to aid in the striking of medals or coins process. The die or mold is used to produce multiple medal or coin blanks using the transferred design.
