How Do High-Precision Cnc Machine Tools Carve Designs Into Master Hubs Or Dies For Striking Medals And Gold Coins?
CNC machines are employed to make master hubs, which are used for the striking of gold medals and coins. This article provides a brief description of the CNC Programming Process.
CAD (Computer-Aided Design) software can be utilized to create a digital 3D representation of the medal or coin design.
The CAM software (Computer Aided Manufacturing) generates instructions and toolpaths for CNC machines with the help of a 3D model.
Selection of Die Material-
CNC machining is done using master hubs or dies constructed of sturdy and high quality materials such as steel, brass or hardened alloys. These materials can withstand high pressure striking processes and ensure exact reproduction of the designs.
Setup and Fixtures
For precise machining, the chosen material is fixed securely to the CNC machine's table or vice versa. It is essential to fix the workpiece properly in order to avoid vibrations during the machining.
CNC Machining Process
CNC machines use tools like endmills or ballmills that engrave designs on the die or master.
The CNC machine will follow the program-defined toolpaths to remove the materials from the blank block according to the 3D design specifications.
Different sizes and types of cutting tools are used to achieve various depths, contours and the details of the coin or medal design.
CNC machines are equipped with computer algorithms which control their movements and provide accuracy as low as micrometers.
Refinement and Finishing
The hub master, also known as a die, is refined.
Surface finish can be obtained with the help of hand-polishing or special tools.
Quality Control, Inspection and Testing
The final die, or hub is then put through to a thorough inspection using the aid of measurement instruments, such as micrometers, gauges and other optical measuring instruments, to ensure it is in compliance with all design specifications.
Treatment and hardening (optional).
Some dies might undergo additional treatments, such as surface or heat hardening to enhance durability and resistance to wear during the striking process.
CNC machines are able of reproducing intricate designs on dies and master hubs with a high degree of precision. These machined tools are critical to create gold medals or coins that are consistent, precise and fine details.

What Happens When The Janvier Machine Transfer Gold Medals Or Coins From A Master Hub To A Working Hub?
A Janvier machine, sometimes known as a pantograph or reducing device is a special device used in the minting process to transfer an image of a medal or coin from a master hub to the hub that is working. Here's a brief overview of how it works. Master Hub Creation-
The master hub is the die or mold, that contains exactly the design of the medal or coin. It's usually produced through CNC machine or other precise methods to guarantee accuracy.
Janvier Machine Installation
The Janvier Machine consists of two parts: a stylus to trace the design and a cutting tool that cuts out the design.
The Janvier machine is equipped with an incredibly secure master hub. This serves as the basis upon which the design can be transferred.
Tracing the Design-
The stylus of the Janvier machine follows the contours and details of the design that is on the master hub. As the stylus moves on the surface of the master hub it tracks its contours.
Reducing Design-
The Janvier machine can also reproduce the pattern traced onto the working hub. This hub is typically made from a softer material like nickel or steel, as opposed to the hub used in the master.
The cutting tool reduces or copies the design to the hub that is working with a smaller or less size compared to the master hub. This is crucial for the process of coining because it permits medals or coins to be struck in the size desired.
Precision and Accuracy
Janvier machines are operated with a high degree of precision to ensure a precise transfer of designs from master hub to working hub. It replicates even the tiniest details and contours accurately.
Quality Control
The final working hub undergoes quality checks to ensure it meets the specifications for striking and is precise.
More Processing
The Janvier machine's hub of working is utilized to make coins or medals. It is used as a mold or die for creating numerous blanks for coins or medals with the transfer design.
The Janvier machine plays an important part in the production process because it permits the exact reproduction and resizing of intricate designs on medals and coins from a working hub into the master hub. The working hubs can then be used for the production process of mass-produced coins or medals.
