The Selection of Materials
CNC machining of the master hub and die makes use of robust, high-quality, durable materials like steel, brass or hardened metals. These materials are able to endure high-pressure strikes and provide accurate replication of the model.
Fixtures and Setup
The chosen material is secured to the worktable of the CNC, vice or vice to ensure precise machine. A proper fixturing technique is vital to prevent vibrations or movement during machining.
CNC Machining Process
CNC machines utilize end mills and ball mills as cutting tools to carve designs into master hubs and dies.
The CNC machine utilizes the tools that are programmed, and removes the material precisely from the block of material based on the 3D models specifications.
Cutting tools come in different sizes and shapes to produce different depths patterns and contours on a coin or medal.
The process of machining is extremely precise, with the CNC machine's movements being controlled by computer-generated algorithms, ensuring accuracy down to micrometer-level tolerances.
Refinement and Finishing
After the initial machining is complete, the die or master hub undergoes further refinement.
With the help of special tools, or by polishing, smoothing or finishing the surface, you will be able to ensure that it meets the required standard.
Quality Control and Inspection
The final die, or master hub, is examined with precision using tools such micrometers. gauges, and optical measuring instruments.
Hardening and treatment (optional).
Some dies will undergo surface or heat treatments to increase their durability.
The precision and capabilities of CNC machines allow for the precise reproduction of intricate designs onto master hubs or dies. The machined dies are vital for accurate and consistent casting of gold coins or other medals.

What Can Laser Technology Do? Employed To Improve The Quality Of Gold Coins And Medals"Die" Surfaces?
This process uses laser technology to refine and create exact details on the dies that are used to make gold coins and other types of medals. Here's how to perform surface refinement using laser technology.
Laser technology can be used to refine the surface of the master hub or die following initial processing. It is used to remove the burrs, imperfections and other surface imperfections.
Detail Enhancement-
Laser techniques for engraving and ablation can be used to enhance or improve intricate details of the master hub or die. Lasers are able to precisely etch or remove materials to create intricate lines, textures, or complex designs that are difficult to achieve through conventional cutting.
Microstructuring-
Laser microstructuring produces microscopic details and textures on the surface die. This process can create patterns or textures to enhance the appearance and security features of the appearance of medals or coins.
Treatment for Hardening or Surface Hardening
Laser technology may be used in certain instances to treat or to harden master hubs or dies. This can improve the durability and wear-resistance of the surface.
Precision Alterations
Laser technology allows precise adjustments or corrections to be made to the master hub or die without altering the overall geometry. This allows for adjustments to the surface to fix any imperfections, discrepancies or flaws which could have an effect on the quality or worth of the coins or awards struck.
Controlled Material Removal
Laser ablation allows for precise material removal. This is especially useful for areas that require precise details to be defined. It's a noncontact method for removing material, which ensures the integrity of the space.
Laser technology can be used to enhance details and to refine dies. This improves surface quality and accuracy. This technology is a complement to traditional machining methods, allowing precision manipulation and improvement to the surface characteristics of dies essential to creating high-quality gold awards or gold coins.

How Do Dies Get Polished? Ensure That Gold Coins And Medals Have The Perfect Surface?
Meticulously polishing dies by hand is vital to the creation of gold coins and medals to ensure a smooth, flawless surface. There are a variety of reasons for this. Detail Reproduction- Hand polishing removes imperfections, burrs, or other irregularities from the die's surface. The smooth surfaces permit a better reproduction of delicate details and intricate features on the medals struck or coins.
Quality of the coin or medal is improvedA polished dash will ensure that the coins or medals have crisp lines, well-defined edges as well as relief. It increases the aesthetics and the quality of your final product.
Reduced Tear and Wear Polishing is a fantastic way to reduce friction and wear while striking. A smooth die's surface minimizes the possibility of imperfections or inconsistencies with the struck coins or medals due to rough surfaces of the die.
Consistency in Striking- Hand-polished dies provide a consistent striking surface that ensures uniformity during the process of minting. It is crucial to ensure the precision, depth and quality of the design across multiple coins or awards.
Durability and longevity of DiesDies with a high polish are less susceptible to damage or wear while striking. Dies are stronger and last longer and allow for a greater number of strikes to be achieved without sacrificing quality.
Precision and Accuracy. Hand polishing enables engravers refine, fine tune and make sure that specific areas are perfect on the die. The details will be accurately depicted on the engraved coin or medal. This level contributes to precision in the final product.
Quality Control: Polishing is an important element of quality control. The inspection of the die while hand polishing is a way to identify and correct any imperfections or defects prior to the process of striking.
Surface Finish Polishing can be used to create a unique appearance or surface, which enhances the appearance of coins or medals, or give them distinctive particularities.
Hand polishing gold dies and medals to perfection is crucial to create high-end, highly precise, and visually appealing products. It is a significant difference in the appearance of the product in its quality, consistency and longevity.
