What Is The Process By Which Janvier Transfer The Gold Design Of A Coin Or Medal That Is On The Master Hub To An Operational Hub?
A Janvier machine is also known as a pantograph, or reduction machine. It is employed to transfer the designs of a coin or medal from the master to an operating center. This is a brief overview of the Master Hub Creation.
The master hub is the original coin or medal die or mold. The master hub is usually produced using CNC methods of machining 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, and an aide-memoire cutter that replicates the design.
The Janvier machine comes with a master hub which acts as a template to guide the transfer of design.
Finding the design
The stylus on the Janvier machine tracks the contours and fine details of the design on the hub master. The stylus on the Janvier machine captures the shape of the surface as it moves along the surface.
Reduce the Design
The Janvier machine also replicates the traced pattern onto the hub that is in use. The hub is usually composed of softer materials like nickel or steel, as opposed to the hub that is used as the master hub.
The cutting tools reduce or duplicate the design at the smaller scale or in a smaller size in comparison to the master hub. This reduction is essential for the process of coining since it allows coins or medals to be struck in the desired sizes.
Accuracy and precision
Janvier is a precision machine that assures a perfect transfer of designs from the master hub onto the working hub. It faithfully reproduces the smallest contours and details.
Quality Control
The resulting working hub will be subjected to quality checks and inspection to ensure that the transferred design matches the specifications and precision required to strike it.
More Processing
The Janvier machine's hub of working is used to strike coins or medals. It acts as a mold or die to create numerous blanks for coins or medals with the transferred design.
Janvier machines are essential to the production of medals and coins. They enable the precise replication of intricate coin or badge designs. These hubs will be used to produce mass quantities of medals or coins using the striking process.
