CNC machines use cutting tools, like end mills or ball mills, that cut the design into the die or master hub.
The CNC machine follows the preprogrammed toolpaths, precisely removing material from the blank block in line with the 3D model's specifications.
Different sizes of cutting tools and types can be used to create different dimensions, contours, and depths on the medal or coin.
CNC machines are controlled by computer algorithms to ensure precision down to micrometer-level tolerances.
Refinement and finishing
The hub master, also known as a die, is then refined.
Surface finishes can be enhanced by detailing or polishing surfaces using hand tools, or using specialized equipment.
Quality Control Inspect and Test
The final die, or hub is then undergoing to a thorough inspection using the aid of measurement instruments, such as gauges, micrometers and optical measuring instruments to ensure that it meets the requirements of the design.
Treatment for Hardening (Optional)
Certain dies undergo surface or heat treatments to increase their durability.
The precision and capabilities of CNC machines allow for the exact reproduction of intricate designs onto master hubs or dies.

What Are The Reasons Why The Dies Used Strike Gold Coins And Medals Undergo Vacuum-Hardening Processes
The hardening by vacuum of dies used to strike gold medals and coins is accomplished by exposing them to high temperatures under controlled conditions in a chamber. Here's a brief overview of the dies for vacuum hardening.
It is crucial that dies used to create medals and coins are completely free of any residues and contaminants.
Loading into Vacuum Furnace
Die dies are kept in the vacuum furnace, which is a specially designed heat-treating chamber capable of creating an atmosphere of vacuum.
Evacuation of Aircraft
The vacuum furnace draws air from the chamber, creating a controlled vacuum environment devoid of oxygen or other gases. This helps to prevent burning and also to guarantee uniform heat treatments.
Heating Phase
The furnace is then heated up to the required temperature to harden the dies. The temperature range is determined by the type of material and the process of hardening.
Bathing at high temperatures-
Die dies are kept at high temperatures for a specific duration, allowing the material to reach the hardness that is desired and also to preserve metallurgical structures.
Quenching and Cooling
Utilizing specialized techniques, dies are quickly cooled down or quenched after the soaking process. This fast cooling process assists in locking the desired hardness of the steel.
Tempering Optional
In some instances the tempering process is performed following the stage of hardening. Tempering is the process of heating dies to a lower temperature, which helps reduce internal stress and increase the toughness of the die while maintaining its toughness.
Quality Control and Inspection
The hardened molds are thoroughly inspected and tested to ensure that the dies meet the requirements.
Post-Treatment Handling-
Die dies are then coated or polished, and are used to make coins or medals.
The process of hardening by vacuum enhances the strength, durability of the dies, their wear resistance and the life of the dies used to create gold medals or coins. By ensuring a controlled and contaminant-free environment the process offers a consistent and reliable way to harden the dies.

Why Are Dies Polished By Hand In Order To Provide A Perfect Surface For Gold Coins And Medals?
There are many reasons why it is vital to polish dies manually in order for them to have a smooth, flawless surface. Enhanced Detail reproduction When you polish the die by hand, any imperfections, burrs or irregularities are removed from the surface of the die. Smooth surfaces allow intricate details to be more easily recreated on the medals and coins.
A die that is polished produces coins and medals that have more defined edges, sharper relief and clearer particulars. The final product will have a higher aesthetic quality and attraction.
Reduction of Wear and Tear Polishing may reduce friction during the process of striking. A smooth surface on the die reduces the possibility of irregularities or defects appearing on the medals or coins struck with rough surfaces.
Consistency in Striking. Hand-polished dies create a consistent striking face, which ensures uniformity throughout the process of minting. It is important to maintain the precision, depth and quality of a design across multiple coins or awards.
Die Durability - Well-polished Dies are less likely to break or worn out during the striking process. The dies are stronger and last longer, which allows for a greater number of strikes to be made without compromising on the quality.
Accuracy and Precision- Hand polishing allows engravers to fine-tune and refine certain areas of the die, making sure that the exact details are duplicated on the engraved medals or coins. The accuracy of a final product is enhanced due to this level of precision.
Polishing for Quality Control is an integral part of the process to ensure quality. The die is inspected during the process of hand-polishing to detect any defects or irregularities and rectified prior to the die is struck.
Surface Finishing - Polishing imparts particular surface finishes and textures that improve the visual appeal or provide unique characteristics to coins and medals that have been struck.
In the end, polishing hand-polished gold dies and medals to a high standard is vital for producing high-quality, precisely precise, and visually appealing products. It can have a major influence on the final product's appearance, durability and consistency.

How Are Gold Blanks Being Fed And Stamped Using High Pressure In Coin Presses For Minting?
During minting gold medals and coins are produced by stamping them under pressure. This article will provide an overview of the process involved in loading blanks
The gold blanks are put into the feeder system that is connected to coin presses. This feeder ensures that blanks are always delivered to the machine.
Feeding Blanks to the Press
This feeder system makes sure that every blank is positioned precisely in the chamber for stamping. The feeder system guarantees that every blank is precisely placed to allow for stamping.
Alignment of Position
The blanks that are in the press chamber are aligned, positioned and perfectly oriented for the stamping.
Fighting Under Pressure
A coin press applies pressure on gold-plated blanks using two dies, one stationary and the second moving. The stationary die is the negative impression of the coin's design while the moving die is the hammer that hits the blank.
The die that moves transfer the design of the blank onto its surface with a great deal of force. The pressure of the dies imprints the designs, resulting in the raised reliefs and details of the medal or coin.
Repetition Striking (Optional)*
To produce a more sharp image or more defined design Multiple strikes can be applied to better quality coins and medals, specifically proof editions. Each strike fine-tunes the details in the blank.
Ejection and collection
Once struck, the freshly minted medals or coins are ejected from the press and placed in trays or containers. They undergo inspection for quality control to ensure that the stamped designs meet the specified standards and criteria.
Post-Processing-
The appearance of the medal or coin might require additional processing like edge lettering (either edge or reeding) or post-strike treatment.
Stamping with high pressure, which creates a design onto the gold blanks, is crucial, as this transforms them into finished coin or medals that are used for collectors, circulation, or commemoration. Precision is required, as even the slightest deviation in the pressurization or alignment of the gold-plated blanks may affect the look and quality of the finished product.
