What Are The Methods Used By High-Precision Cnc Cutting Machines Cut Designs Into Dies Or Master Hubs To Strike Gold And Medals? Coins?
In the production of master hubs (or dies) to make gold coins or medal striking CNC machines that have high precision are crucial. Here is a brief outline of the CNC Programming Process.
Software known as CAD (Computer Aided Design), is used to make digital 3D models for coin and medal designs.
The software CAM (Computer Aided Manufacturing) generates instructions and toolpaths for the CNC machine with the help of a 3D model.
The selection of Die Materials
CNC Machining is performed on dies or master hubs that are made of strong and durable quality components like steel, brass, or hardened alloys. These materials are able to stand up to high-pressure striking and ensure exact reproduction of the model.
Fixtures and Setup
For precise machining, the chosen material is fixed securely to the CNC machine's table or vice versa. The correct fixing is crucial to prevent vibrations during the machining.
CNC Machining Process-
CNC machines employ cutting tools that include ball mills or end mills, to carve a design into a die or a master hub.
The CNC machine follows the preprogrammed toolpaths, precisely removing material from the blank material block in accordance with the 3D model's specifications.
Cutting tools can be of different sizes and types to create different depths, contours and designs on a coin or medal.
CNC machine movements are controlled by computer software, which guarantees precision to the micrometer level.
Finishing and Refinement-
After initial machining the master hub or die is subject to the process of refinement.
Surface finish can be achieved through hand-polishing, detailing or special tools.
Quality Control Inspection and Testing
The finished die, or master hub, is examined by using instruments such as a micrometers. gauges, and optical measuring instruments.
Hardening Treatment (Optional)
Some dies are subjected to additional treatments such as heat hardening, surface treatments and even heat to increase the durability during striking.
CNC machines are able of reproducing intricate designs on master hubs with a high degree of precision. These machined dies serve as the essential tooling needed for striking gold coins or medals that have consistency, accuracy and exquisite details.

How Can A Janvier Transfer The Gold Design Of A Coin Medal That Is On The Master Hub To A Working Hub?
The Janvier machine, sometimes known as a pantograph, or reducing machine is a special machine used in the process of minting that transfers the design of a medal or coin from a master hub into a working hub. This article will provide an overview of how this Master Hub Creation works.
The master die is the primary mold or die that contains the exact design on the coin. The master hub is usually manufactured using CNC machines or other techniques to ensure precision.
Setup for Janvier MachineSetup for Janvier Machine
The Janvier machine has an instrument to trace the design on the hub master as well as an aide-memoire cutter that replicates the pattern.
The master hub is placed on the Janvier machine, and serves as a template upon which the design will be transferred.
Tracing Design-
The stylus of the Janvier machine follows the contours and details of the design on the hub master. As the stylus moves across the surface of the master hub, it captures the design's contour.
Reduce the Design
The Janvier machine simultaneously copies the drawn-out design onto the work hub. It is typically made from softer materials as opposed to the master wheel like steel or nickel.
The cutting tool reduces or reproduces the design on the working hub at an enlarge or decreased dimensions compared to the master hub. This is essential for the process of minting, since it allows for the striking of medals or coins in the exact size.
Accuracy and precision
Janvier's machine operates with precision, ensuring an exact transfer of data from the master hub onto the working hub. It replicates even the smallest details and contours faithfully.
Quality Control-
Quality checks and inspections are conducted to confirm that the design used is compatible with the requirements and accuracy needed to strike the design.
Further Processing
The Janvier working hub is an tool for the striking process of medals or coins. The mold or die is used to make multiple medal or coin blanks using the transferred design.
Janvier is a crucial element of minting, because it can accurately replicate and reduce intricate designs of medals or coins. These working hubs will then be utilized to mass produce medals or coins using the striking process.

Enhancement of Appearance-
Gold plating and Gilding Coins and gold medals can be coated with a fine gold layer. This makes the medal or coin the appearance of a luxurious, glossy surface.
Aesthetic effects
Patina or antique finishes are made by special coatings or chemical treatments. This creates character and depth to the design by creating an aged, oxidized appearance.
Coloring and Colorization- Certain areas of a medal or coin are colored using special coatings or enamels. This is done to highlight certain features of the design, to add interest, or to create visually appealing designs.
Anti-Tarnish Coatings-
