How Does A Janvier Machine Transfer The Design Of The Gold Coin Onto The Hub That Is In Operation?
A Janvier machine is also called a pantograph, or reducing machine. It's used to transfer the appearance of a coin medal from a master to an operating center. Here's a quick overview of this Master Hub Creation.
The master hub is the original coin, medal or coin mold. The majority of them are made by CNC machining or other precision methods to guarantee accuracy.
Janvier Machine Setup
The Janvier Machine is comprised of two elements that include a stylus for drawing the design, and a tool that cuts out the design.
The Janvier machine comes with a master hub that acts as a template to guide the transfer of design.
Tracing Design-
The Janvier stylus in the machine captures the contour of the design as it travels along the hub's surface. As the stylus moves across the hub's surface, it tracks its contours.
The Design-
In tandem with the Janvier the cutting tool replicates the traced designs onto the hub of the machine which is normally made out of an abrasive material such as steel or nickel.
The cutting tools cut or duplicate the design at a smaller scale, or at a smaller size, in comparison to the master hub. This is crucial for the process of coining since it allows medals and coins to be struck at the sizes desired.
Accuracy and precision
Janvier is a high-precision machine that guarantees a precise transfer of designs from the master hub to the working hub. It replicates even the tiniest details and contours accurately.
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 working hub acts as an instrument to facilitate the process of striking coins or medals. It's used as a mold, or die to create a variety of blank coins or medals with the design transferred.
Janvier's machine is crucial in the coining process. It allows accurate replication and reduction from a master to working hubs for intricate designs. These hubs are utilized to create large amounts of medals and coins by using the striking method.

How And Why Is It Possible To Create Certain Finishes Or Textures, Like Matte Or Textured Surfaces?
This technique is used to create matte or textured finishes on gold medals or coins. Here's what this technique is and how it is employed.
Surface preparation- The metal or coin is placed in the form of a cabinet or chamber with a nozzle attached to an air compressor. This chamber is often covered to protect the abrasive materials used in the process.
The medal or coin is then sprayed with abrasive substance, which can include sand, glass beads silicon carbide, or aluminum oxide.
High-Pressure propulsion: Abrasive particles are delivered to the surface of a surface using compressed gas or other high pressure system. The texture of the surface is created through the force and speed of the particles.
Texture creation. The impact of an abrasive surface changes the surface topography to produce a rough, matte finish. This technique lets you roughen specific regions, or create a texture that is consistent across the surface.
Sandblasting that is controlled - Sandblasting can be controlled by the intensity, duration and the angle of application. This allows for different types of finishes and textures. Different types of abrasives and levels of pressure produce different results.
Sandblasting: Why is it necessary?
The process of sandblasting allows the creation of different types of textures and surfaces, such as mattes, frosted or rough surfaces. This can create visual interest and unique features for the coins or medals.
Aesthetic Improvement- Sandblasting changes the appearance of a surface. It disperses light reflections and decreases shine. This improves the aesthetic appeal of a medal or coin. Surfaces that are matte, like those that reduce glare, may highlight particular design features.
Anti-Glare Property: Sandblasting can create matt or textured surfaces which lessen reflections, glare and make the medal or coin more appealing.
Contrasting Design Elements. Sandblasting creates contrast between polished and textured ones on the coin. It can be used to highlight specific design elements or to create visual depth.
Sandblasting permits customization and artistic expression as well as the creation of unique medals or coins that feature textures or finishes designed to meet specific specifications for design.
Sandblasting can create different textures and finishes on the gold coins and medals. This enhances their appearance, appeal and aesthetics.
