Fixtures and Setup
Fixing the material securely onto the CNC machine's worktable, or vice is vital for precision machining. It is essential to avoid the material from moving and vibration during machining.
CNC Machining Process
CNC machines make use of cutting instruments that include ball mills or end mills, that carve a design into the form of a die or master hub.
The CNC machine follows the programmed toolpaths, precisely removing materials from the blank material block in line with the 3D model's specifications.
To get different depths of contours or details in the coin design It is possible to use various cutting tools.
CNC machines can be controlled by computer algorithms that ensure precision up to micrometer-level tolerances.
Refinement and Finishing
The hub master, also known as a die, is refined.
Smoothing, polishing and detailing with a hand-held device or using specialized tools make sure the finish of the surface meets the standards required.
Quality Control and InspectionQuality Control and Inspection
The die, also known as the master hub, is examined by using instruments such as a micrometers. gauges, and optical measuring instruments.
Treatment for Hardening (Optional)
The dies may be treated using heat hardening or surface treatments to improve durability and wear resistance during the striking process.

What Is The Process By Which The Janvier Machine Transfer Gold Coins Or Medals From A Master Hub To The Working Hub?
A Janvier machine can also be referred to as pantograph, also known as a reducing machine. It's used to transfer the design of a coin or medal from a master into an operating center. Here's a brief overview of how the Master Hub Creation works.
The master hub is the primary coin, medal or coin mold. It's made with high-quality CNC machining.
Installation for Janvier Machine-
The Janvier Machine consists of two parts: a stylus to trace the design, and a tool that cuts the design.
The Janvier machine has a master wheel that is connected to the machine. It is used as a model to which designs will be transferred.
Tracing Design
The stylus of the Janvier machine tracks the contours and fine details of the design that is on the master hub. As the stylus moves across the hub's surface, it records its profile.
Reduce the Design
The Janvier machine simultaneously copies the drawn-out design onto the work hub. It is typically made from softer materials than the master wheel, like steel or nickel.
The cutting tools reduce or reproduce the design on a smaller scale, or in a smaller size compared to master hub. The smaller size is crucial for the production of medals and coins which allows them to be struck with the desired dimensions.
Precision and Accuracy
Janvier machines operate precisely to ensure the exact transfer of the design from master hub to working hub. It can reproduce every single detail and contours accurately.
Quality Control
The working hub is subject to quality control and inspection to ensure it is in line with the specifications and is accurate for the strike process.
Further Processing
The hub of the Janvier's can be utilized as an instrument in the striking of medals and coins. It acts as a mold or die for creating numerous blanks for coins or medals that have the design transferred.
Janvier machines are vital to the production of coins and medals. They permit the exact reproduction of intricate coins or badge designs. The hubs that are working can be utilized in the production process of mass-produced medals or coins.

Why Do Dies Need To Be Polished Manually In Order To Achieve A Flawless Finish On Gold Awards And Coins?
Hand-polishing dies provide an even and smooth finish for gold coins as well as other medals. The more polished the surface is, the more accurate quality reproduction of the fine details and intricate designs on the medals or coins.
Improved coin or medal quality- A polished dash ensures that the coins or medals have sharp edges, well-defined edges as well as relief. It improves the aesthetics and quality of the final product.
Reduced Wear and Tear- Polishing helps reduce friction and wear during the striking process. A smooth die surface reduces the possibility of irregularities or defects appearing on the medals or coins struck with rough surfaces.
Consistency is key when striking. Hand-polished Diets offer an even surface for striking and ensuring consistency. To ensure that the design is maintained in its precision as well as its depth and overall quality the consistency is crucial.
Durability of the DiesDies that are well-polished are less prone to damage or wear during the striking process. Dies are stronger and last longer that allows an increased number of strikes to be made without sacrificing quality.
Precision and Accuracy. Hand polishing allows engravers to fine-tune, refine and refine specific areas of the die. The specifics will be precisely reproduced on the struck coin or medal. The accuracy of a final product is increased with this degree of precision.
Quality Control: Polishing is an important part of quality control. Polishing the die by hand allows you to identify and correct any inconsistencies or imperfections prior to the striking process.
Surface Finish - Polishing adds a unique surface texture or finish to coins and medals and increases their appeal.
Hand-polishing the dies for gold medals and coins is crucial to ensuring that minted products are high quality, exquisitely detailed, and of high aesthetic appeal. It makes a big difference in the appearance of the product as well as its durability and consistency. longevity.

How Do Gold Blanks Are Loaded Into Coin Presses At High Pressure And Stamped?
During the minting process gold blanks are loaded into coin presses, where they are stamped under high pressure to transform them into pieces of gold or coins. Here is an overview of how to load blanks.
In a feeder system connected to the press, gold blanks have been previously prepared and quality checked. This feeder system ensures an ongoing supply of blanks for the press.
Blanks for Feeding to the Press
This feeder system makes sure that each blank is placed precisely inside the chamber for stamping. This allows for precise positioning of the blanks.
Alignment and Positioning
The blanks are placed in the press, and then placed into the striking area making sure that they are centered and perfectly oriented to perform the stamping.
Moving at High Pressure
Coin presses gold blanks using high pressure by using two dies - one stationary and the other moving. The stationary die contains the negative impression of the design of the coin, and the one that moves is the hammer that strikes the blank.
The die that is moving strikes the blank with significant force, which transfers the design to the surface of the blank. The dies pressurize the design and create relief raised on the coin or medal.
Repeated Striking (Optional)-
For medals or coins with higher quality such as collector's or proof editions, multiple strikes could be employed to produce an even more sharp, clear visual or a design. Each strike refines the surface details of the blank.
Ejection and collection
Once struck, the newly-minted coins or medals are released from the press and collected in containers or trays. They are inspected for quality control, to make sure that the designs are in line with the requirements of all standards and specifications.
Post-Processing-
Minted medals or coins may undergo additional processes such as edge lettering edge reeding or post-strike processes based on the design requirements or specifications for mints.
The process of stamping under extreme pressure is essential in that it imparts the desired design onto the gold blanks, turning them into finished pieces of gold ready for circulation, collection, or commemoration. This process is extremely precise, since any slight variation in alignment or pressure can affect the quality and appearance of the final product.
