CNC Machining is performed on dies or master hubs that are made of strong and durable quality materials such as steel, brass, or alloys that are hardened. These materials are able to endure high-pressure strikes and provide precise replication of the model.
Setup and Fixtures
To ensure precision in machine work, the material is securely fixed to the CNC machine's table or vice versa. The correct fixing of the material is vital to stop any movement or vibrations during the processing.
CNC Machining Process-
CNC machines employ cutting tools, such as ball or end mills to carve a design into a die or a master hub.
The CNC machine takes material off the blank material blocks according to 3D specifications.
There are a variety of types and sizes for cutting out the design of a medal coin.
CNC machines can be controlled by computer programs that ensure precision up to micrometer-level tolerances.
Finishing & Refinement
After the initial machining, the hub or die is subject to refining.
Surface finish can be obtained with the help of hand-polishing or other tools that are specialized.
Quality Control and Inspection-
The final die or master hub undergoes strict inspection using measurement tools such as gauges, micrometers or optical measuring instruments to verify that the die is in good condition and conforms to design specifications.
Treatment and hardening (optional).
Certain dies are heat-hardened or treated on the surface for increased durability and resistance to wear.
The precision and power of CNC machines allows for accurate replication of intricate designs onto master hubs or dies.

What Is The Reason Dies For Gold Coins Or Medals Are They Hardened By Vacuum?
The hardening by vacuum of dies used to create gold medals and coins is accomplished by exposing them to extreme temperatures in controlled conditions inside a vacuum chamber. This is the basic information on the dies for vacuum hardening.
The dies used for striking medals or coins are created by making sure they are free of any residues or contaminants.
Loading in Vacuum Furnace
The dies are put into a vacuum-environment chamber.
Evacuation of Air-
The vacuum furnace filters the air in the chamber, creating a controlled vacuum, devoid of oxygen or other gases. This guarantees uniform heating and prevents the process of oxidation.
Heating Phase
The furnace is heated to the required temperature for hardening of dies. The temperature range varies based on the material used and the hardening processes.
Soaking in High Temperatures
The dies stay at elevated temperatures for a specified period of time, which allows materials to attain the level of hardness desired and also maintain the metallurgical structure.
Quenching (or cooling)
The dies will be quenched or rapidly cooled after the soaking. The speedy cooling allows the metal achieve the desired hardness.
Tempering (Optional).
In certain cases the process of tempering may occur after hardening. The dies are heated up at a lower temperature in order to ease internal stress and improve toughness, while maintaining hardness.
Quality Control & Inspection
Hardened dies are subjected to rigorous quality inspections and tests to ensure that they meet the standards for strength, hardness and tolerances for dimensional dimensions.
Post-Treatment Handling-
The dies will then be processed further like polishing or coating prior to being used to create the strike of the coin or medal.
Vacuum hardening improves the durability, durability, and wear resistance of the tools which are used to make gold medals or coins. The process of hardening by vacuum is a reliable and predictable method to harden dies in a controlled, safe environment free of any contaminants.

Why And How Are Premium Gold Blanks Weighed And Measured Before Being Made Ready For The Minting Process?
High-quality gold blanks are meticulously prepared for the minting process to ensure consistent and precise gold medals or coins. This is how and why the process of preparation works. Gold Material Selection - Only pure gold is used to make blanks. The refinement process is generally to ensure it meets the standards of purity for coinage.
Gold Blanks are created by blanking. Blanking is the act of cutting discs or planchets to the shape of coins out of gold by using special equipment or stamping.
Accurate Measuring and Weighting
Weighing - Each of the blanks is weighed individually to ensure it is in line with the weight requirements for the coin or the medal. This process ensures that every item contains exactly the amount of gold needed for each denomination.
Measurement Instruments - Precision instruments are employed to measure the diameter, thickness and overall dimensions of each blank to ensure that it is uniform.
Inspection and Quality Control
Visual Inspection- Each piece is visually examined to find any imperfections on the surface, irregularities or impurities which could impact the overall quality.
Rejecting non-conforming blanks In order to maintain consistency and uniformity, all blanks that don't meet the weight, dimension or quality standards are rejected.
Justification for preparation
Consistency in the Minting Process: Precisely measured and weighed blanks will ensure uniformity. Dimension and weight consistency results in uniformly struck and creates medals and coins that are of the same value and quality.
Accurate Gold Content: Each blank's weight is precisely calculated to ensure that the final medal or coin contains the intended amount of gold, ensuring accuracy in value and purity.
Uniform Blanks - Prevent any variations in size or weight which may impact on the coin’s or medal’s value, legality or usability for trade or circulation.
Quality Assurance – Strict quality controls during blank preparation will ensure that only blanks of high-quality and free from imperfections are used during the minting process. This decreases the chance of flaws being present in the final product.
Legal Compliance. For coins that are designed for circulation or even for commemorative use it is vital to comply with the requirements. This will ensure that they conform to all legal requirements and standards established by regulatory bodies and mints.
To make accurate, high value and legally compliant currency or medals, it is essential that gold blanks be prepared with accuracy and precision.
