CAM (Computer Aided Manufacturing), software that creates toolpaths, instructions and commands for CNC machines built on 3D models.
How to choose the right Die Material
CNC processing of the master hub and die uses durable, high-quality materials, such as brass, steel or other hardened metals. They can withstand the rigors of high pressurizing processes and guarantee exact reproduction of the designs.
Fixtures and Setup
The chosen material is properly fixed to the CNC's worktable and vice or vice to ensure precise cutting. The correct fixing is crucial to prevent vibrations during machining.
CNC Machining Process
CNC machines employ cutting tools like ball mills or end mills to cut the design in the hub master or die.
The CNC machine follows the programed toolpaths and precisely removes materials from the blank material block according to the 3D model's specifications.
Cutting tools can be of different sizes and shapes to achieve different depths, shapes and designs on a coin or medal.
CNC machines can be controlled by computer algorithms that ensure precision up to micrometer-level tolerances.
Finishing, Refinement and Finishing
The hub master, also known as a die, is then refined.
Smoothing, polishing and sanding by hand or using specialized tools ensure that the surface finishes meet the requirements for.
Quality Control and Inspection
The master hub or die is to be checked with measuring instruments such as gauges or micrometers to verify that it is in line with specifications for the design.
Treatment of hardening (optional) and Treatment
Certain dies could undergo additional treatments like surface or heat hardening to increase the durability and wear resistance during the striking process.
CNC machines can reproduce intricate designs precisely using master hubs and dies. These dies are the essential tools for making gold medals and coins with consistency, precision and high-quality detail.

What Is The Process By Which The Janvier Machine Transfer Gold Medals Or Coins From A Master Hub To A Working Hub?
The Janvier machine (also known as pantographs or reducing machines) is a unique device that allows the transfer of the design of a medal or coin from the master hub onto the operating hub. This is a brief overview of this Master Hub Creation.
Master dies are the primary mould or die that has the exact design of the coin. It is made through CNC machining, or using other precision techniques.
Janvier Machine Installation and Setup
The Janvier machine consists of a stylus which trace the design on the master hub, and cutting tools that copy the design on the working hub.
The master hub is fixed to the Janvier machine and acts as a template to where the design can be transferred.
Tracing the design-
The Janvier stylus follows the design's contours as well as the details of the hub. As the stylus moves along the surface of the master hub, it records the design's profile.
The Design of the Home
The Janvier machine simultaneously copies the traced-out design onto the hub for work. It is typically made of softer materials than the master wheel, like steel or nickel.
The cutting tool is used to reduce or replicates the design onto the working hub on the smaller or smaller dimensions compared to the hub that is used as the master hub. This reduces the size of the process of coining because it permits medals or coins to be struck in the desired sizes.
Accuracy and precision
Janvier's machine is operated with precision, ensuring that the transfer is precise from the master hub into the hub for operation. It replicates even the tiniest details and contours precisely.
Quality Control
The design and quality of the hub is inspected to make sure that the design of the transfer is in line with the specifications required for the striking processes.
Additional Processing
The Janvier machine's hub of working is used to create coins or medals. It functions as a mold, die or die for multiple coins or medals blanks that have the transferred design.
The Janvier machine plays a crucial part in the process of minting by allowing the exact replication and resizing of intricate designs on coins or medals from a hub that is working to a master hub. The working hubs can then be used in the production process of mass-produced coins or medals.

What Are The Benefits Of Sandblasting For Certain Types Of Finishes Or Textures, Such As Matte Surfaces Or Textured Ones?
Sandblasting is an effective technique to create matte or textured surfaces on gold or silver coin and medals. Why and how do we use this method?
Surface preparation- The coin or medal is placed inside an enclosure or chamber with a nozzle connected to an air compressor. This chamber can be sealed to contain the abrasive substance used during the procedure.
Abrasive Material Select - Abrasive particles such as glass beads, aluminum oxide silica carbide, sand and so on are propelled at high speed on the surface.
High-Pressure propulsion - Abrasive particles can be delivered to the surface of a surface with compressed gas or a different high pressure system. The finish or texture will be determined by the force and speed with which particles impact the surface.
Texture Creation – The impact of abrasive particles on the surface changes the topography of the surface, resulting in an appearance that is matte or textured. This method allows you to roughen certain areas or create a texture consistent across the surface.
Controlled Application - The intensity and duration, as well as angle and the application of sand can be controlled to achieve different textures or surfaces. Different abrasives and pressure levels yield different results.
Sandblasting - Why it is done
Texture variation- Sandblasting may create a variety and finishes like smooth grains, frosted, or grainy textured surfaces. This adds visual interest to the medals or coins.
Aesthetic Enhancement- Sandblasting alters the appearance of the surface by diffusing light reflection and diminishing shine, which may enhance the appearance of the coin or medal's appeal. Matte finishes are an excellent way to highlight the design elements.
Anti-Glare: A matte or textured finish that is created by sandblasting reduces reflections or glare. This makes the medals or coins look attractive and they are more easily read with no unwanted light interference.
Contrasting Elements in Design- Sandblasting is used to create contrasts between different areas which are polished or textured on coins or medal. This is done to highlight certain design features or to give dimension and depth.
Sandblasting can be customized and creative. offers customization options, allowing to express your creativity and artistic flair, as well as the creation of medals or coins with distinctive textures or finishes that are tailored to the specific requirements of design.
