CNC Machining is performed on dies or master hubs made of durable and high quality materials such as brass, steel or alloys that are hardened. These materials are able to stand up to high-pressure striking and ensure precise replication of the design.
Fixtures and Setup
The material selected is secured to the worktable of the CNC and vice or vice to ensure precise machine. It is essential to fix it correctly in order to prevent vibrations during machining.
CNC Machining Process-
CNC machines employ equipment like endmills and ballmills to engrave the design on the die or master.
The CNC machine follows the preprogrammed toolpaths and precisely removes materials from the blank block in accordance with the 3D model's specifications.
Different kinds and sizes of cutting tools may be used to attain different depths, contours, and details of the medal or coin design.
CNC machine movements are controlled by computer algorithm, which ensures precision to the micrometer level.
Finishing and refinement
The master hub, or die, is refined.
Polishing, smoothing, and detailing by hand or using special tools to ensure that the surface finishes meet the standards required.
Quality Control and Inspection-
The master hub, or die, is to be checked using measuring tools such as gauges or micrometers in order to ensure that it is in line with design specifications.
Hardening and Treatment (optional)-
Certain dies can be heated-hardened or treated on the surface for increased the durability and resistance to wear.
The precision and capabilities of CNC machines allows for exact reproduction of intricate designs onto dies or master hubs. Die sets provide the equipment to create gold medals or coins consistently, accurately, and with exquisite specifics.

Why Does A Gold Coin Or Medal Dies Go Through The Process Of Hardening By Vacuum?
To harden dies for gold coins or medals, they are subjected to temperature control in an oven that is a vacuum. Here's a brief overview of the vacuum hardening process for dies Preparation and Cleaning.
To make dies that will be used to create the coins or medals, they should be clean and free of any contaminants or residues.
Loading Vacuum Furnace
Die dies are placed in an environment chamber that is vacuum.
Evacuation from Air-
The vacuum furnace eliminates air from the room, forming an environment of controlled vacuum that is free of oxygen and other gasses. This helps prevent oxidation and guarantees an even heating.
Heating Phase
The furnace is then heated to a certain temperature to harden the dies. The temperature range is based on the specific material and processes for hardening.
Soaking at high temperatures
Die dies are kept at elevated temperatures for a specified period of time, which allows the material to reach the level of hardness desired and also maintain the metallurgical structure.
Quenching and Cooling
With the help of special techniques that allow dies to be quickly cool down or melted after the soak process. This fast cooling process assists in locking the desired hardness of the material.
Tempering (Optional).
In some instances, the hardening process is followed by a tempering procedure. In order to improve strength and reduce internal stress, dies can be heated at temperatures lower.
Quality Control and Inspection
To ensure they meet the standards for hardness and strength Die dies that have been hardened go through an extensive inspection and quality control.
Post-Treatment Handling-
After the hardening process dies are polished or coated prior to the time they are used in the coin process or the metal striking process.
The vacuum-hardening process increases the strength, durability as well as the resistance to wear and longevity of dies used to create medals or coins. The process of hardening by vacuum is an efficient and reliable method to make dies hard in a controlled and safe environment free of any contaminants.

How Do You Make And Weigh Gold Blanks For Minting?
The process of creating gold blanks is extremely careful to ensure that the gold coins or medals produced are consistent and exact. The process that is followed: Preparation Gold Material selection- Only high purity gold is used when making blanks. Gold is usually refined to ensure it meets the standards of purity for coinage.
Gold Blank Production: Gold is transformed into blanks using a method known as blanking or blank cutting. Blanking involves cutting the gold into disks of planchet size or coin size by using specialized equipment or stamping.
The exact measurement and weighting of the items.
Weighing- Every blank is individually weighed to ensure it is in compliance with the weight requirements for the coin or medal. This method ensures that each piece has the exact amount of gold required for the intended denomination.
Measuring. Precision instruments are utilized to determine the diameter, height, and length of each blank. This ensures consistency and conformity to the specifications of the design.
Inspection and Quality Control
Visual Inspection: Each Blank is examined visually to find surface imperfections.
Rejecting Blanks that Are Not ConformingIf a blanket does not meet the minimum weight, dimensions, or quality standards are rejected to ensure consistency and uniformity.
Justification for preparation
Consistency of Minting Process - The uniformity of the minting process is assured by precisely weighting and measuring blanks. Consistency in weight and dimension results in uniformly struck, producing coins or medals of the same quality and value.
Accurate Weight of Gold - Each gold bar has a precise weight that assures purity and value.
Uniform Blanks Help Prevent Variations Uniform blanks help to prevent any weight or size variation that could impact the legality, value, and usability of a coin or medal that is in circulation or in commerce.
Quality Assurance - Strict measures of quality control throughout the process of making blanks ensure that only high quality free of defects are delivered to the minting stage to reduce the risk of flaws appearing in the final product.
Legal Compliance. For coins that are intended for circulation or for commemorative purposes it is vital to follow the specifications. This will ensure they comply with all legal requirements and requirements set by regulatory agencies and mints.
In order to produce accurate, high value legal compliant coins or medals, it is vital that gold blanks are created with accuracy and precision.

How Are Gold Blanks Loaded Into Coin Presses At High Pressure And Stamped?
When the production process is completed gold blanks are taken into coin presses where they are stamped using high pressure. The result is completed coins or medals. Here's an overview of the steps involved in loading blanks
Gold blanks that have been examined and prepared for quality, are loaded into a feeder system connected to the coin press. The feeder system is responsible for maintaining a continuous flow of blanks into the machine.
Feeding Blanks to the Press
The feeder system directs the blanks one at a time into the chamber for striking of the coin press. This allows for precise positioning of the blanks.
Alignment of Positioning
In the press, the blanks are aligned before being placed in the chamber for striking making sure that they are completely centered and oriented for the stamping process.
Moving Under High Pressure
The coin press uses two dies, one stationary and the other that moves. The stationary die is the negative image of the coin's design, while the moving die is the hammer that hits the blank.
The dies strike the blank with lots of force. This transfers the design on its surface. The force exerted by dies creates the design, creating the relief that is raised as well as details on the coin, or medal.
Repetition Striking (Optional)*
To create designs or images that are clearer and more clear, several strikes can be used on premium coins or editions of collectibles. Each strike increases the fine details of the outside of the coin.
Ejection and collection
After being struck, freshly-minted coins or medals are thrown from the press onto 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-
If the mint requires the process, they can apply other processes like edge lettering, reeding of the edges, or post-strike treatment.
The process of stamping gold blanks using high pressure is essential because it prints the design you want to see on the blanks, transforming them into refined coins and medals that can be used for the purpose of commemoration, collection or circulation. This process is extremely precise because any variations in alignment or pressure could alter the appearance and performance of the final product.
