What Is The Process By Which A Janvier Machine Transfer A Gold Coin Or Medal Design To The Working Hub From The Master?
A Janvier machine, sometimes known as a pantograph or reducing machine is a special device used in the process of minting to transfer an image of a medal or coin from a master hub into the hub that is working. This is a brief overview of this Master Hub Creation.
The master hub is the first mold or die that is used to create the exact design of the medal or coin. The master hub is generally made using CNC methods of machining or other techniques to ensure accuracy.
Janvier Machine Installation
The Janvier Machine is comprised of two components which include a stylus that trace the design and a tool which cuts the design.
The Janvier machine is fitted with a master hub, which serves as a template for the transfer of design.
Retracing The Design
The stylus on the Janvier machine follows the contours and details of the design on the hub master. When the stylus is moved across the surface, it records the design's outline.
Reduce the Design
On the Janvier cutting tool, it copies the designs traced onto the central hub of the machine which is normally made out of steel, a soft metal or Nickel.
The cutting tool cuts or duplicates the design onto the working hub at a smaller scale or reduced size when compared to the master hub. The smaller size is critical to the production of medals and coins, making them possible to strike with the desired dimensions.
Precision and Accuracy
Janvier is a high-precision machine that guarantees a precise transfer of design from the master hub to the hub that is in use. It faithfully recreates the most intricate details and contours.
Quality Control
The hub that is created is subject to quality inspections and a final inspection to ensure the transfered design meets the specifications and accuracy needed for the striking process.
Further Processing-
The Janvier working hub acts as an instrument to facilitate the process of striking medals or coins. It is used as a mold or a die to create multiple medals or coins that are blank and have the transfered design.
The Janvier machine plays a crucial role in the minting procedure by allowing the exact reproduction and reduction of intricate designs on coins or medals from a working hub to a master hub. These hubs work for the production of large quantities of medals or coins through the strike process.

How Do Dies Get Polished? Ensure That Gold Medals And Coins Have A Perfect Surface?
There are many reasons why it is crucial to polish dies by hand in order for them to have a smooth, flawless surface. Enhanced Detail reproduction With hand polishing, imperfections, burrs or irregularities are eliminated from the surface of the die. A smooth surface allows complex details to be better recreated on the medals and coins.
Improved coin or medal qualityA polished dash guarantees that the coins struck and/or medals have sharp lines, clear edges as well as relief. This improves the quality and aesthetic appeal of the final product.
Reduced Wear & Tear- Polishing is an excellent option to reduce friction and wear during the process of striking. A smooth surface on the die reduces the chance of inconsistent or flaws appearing on coins or medals struck with rough surfaces.
Consistency in Striking. Hand-polished dummies offer a uniform strike surface, and ensure uniformity in the coining process. Consistency is essential to maintain the design's accuracy, depth and overall quality over many medals or coins.
Longevity: Clean and well-polished Dies are more durable. They're less likely than unpolished ones to wear down or become damaged in the process of striking. They have increased durability and durability, allowing for more strikes, without compromising the quality of the produced products.
Accuracy and Precision Hand polishing allows the engraver to fine-tune specific areas of dies, ensuring that the details are precisely reproduced on medals or coins struck. This level contributes to accuracy of the final product.
Quality Control - Polishing is an integral element of quality control. The die is inspected during the process of hand-polishing to identify any flaws or inconsistencies and corrected before the die is struck.
Surface Finish Polishing can be used to create a unique appearance or surface, that can increase the appearance of metals or coins, or even add unique characteristics.
