The software CAM (Computer Aided Manufacturing) generates instructions and toolpaths for CNC machines using the 3D model.
Selection of Die Material-
Materials of high-quality and long-lasting like brass, steel or alloys that are hardened are chosen for CNC making the master hub or die. These materials are able to stand up to high-pressure striking and ensure precise replication of the model.
Fixing and Setup
To make precise cutting, the material is fixed securely to the CNC machine's table or vice. Fixturing the material correctly is essential to avoid vibrations and movement during machining.
CNC Machining Process
CNC machines utilize end mills as well as ball mills for cutting tools to carve designs into master hubs or dies.
The CNC machine will follow the set toolpaths that are programmed to remove materials from the blank materials block in accordance with the 3D specifications of the model.
Different types and sizes of cutting tools can be used to achieve various dimensions, contours, and other details of the medal or coin design.
CNC machines are controlled by computer programs to guarantee precision to micrometer-level tolerances.
Finishing & Refinement
The die or master hub is refined further after the initial machine.
Surface finishes can be enhanced by finishing or polishing surfaces using hand tools, or using equipment designed specifically for this purpose.
Quality Control Inspection and Testing
To ensure the accuracy and conformity to the design specifications the master wheel or die is put through a thorough examination. Instruments for measuring like micrometers, gauges or optical measuring devices are employed.
Treatment for Hardening (Optional)
Some dies are subjected to additional treatments such as the hardening process and other surface treatments in order to improve durability during striking.
CNC machines provide the precision and precision needed to reproduce intricate designs onto master hubs or dies. These machined tools are critical for striking gold medals or coins with precision, consistency and precise details.

How Does A Janvier Machine Transfer A Gold Coin Or Medal Design To The Hub From The Master?
A Janvier, also known by the name pantograph or reducing machine, can be employed to transfer designs for a medal or coin from a master hub onto a working hub. This is a brief description of this Master Hub Creation.
The master hub is the die or mold, that has the exact design for the coin or medal. It is produced through CNC machineries, or other techniques of precision.
Janvier Machine Setup
The Janvier machine comprises an instrument to trace the design on the hub master and a cutter that duplicates the layout.
The Janvier machine is equipped with the master wheel which is attached to the machine. It is used as a model from where designs are transferred.
Tracing the Design-
The Janvier stylus in the machine captures the profile of the design while it moves along the surface of the master hub. As the stylus moves on the surface of master hub it tracks its contours.
Reduce the Design
The Janvier machine simultaneously copies the traced-out design onto the work hub. It is typically made with softer components as opposed to the master wheel for example, steel or nickel.
The cutting device cuts or copies the design onto the hub of the wheel, but at a lower scale or size in comparison to the hub that is the master hub. This is crucial for the coining process as it permits medals or coins to be struck at the sizes desired.
Precision and Accuracy
Janvier's machine operates with precision, ensuring that the transfer is precise from the master hub into the hub for operation. It reproduces every detail and contour with accuracy.
Quality Control
The hub that is created will be subjected to quality checks and examination to make sure that the transferred design matches the specifications and accuracy required to strike it.
More Processing
The Janvier working hub acts as an instrument to facilitate the striking process of coins or medals. It is used as a mold, or die to create multiple blank coins or medals with the design transferred.
Janvier's machine plays a crucial role in the process of coining. It permits the accurate replication and reduction from an original master to working hubs of complex designs. These hubs work for the production of large quantities of coins and medals by the strike process.
