How Does A High-Precision Cnc Machine Carve Out The Shape To Create The Die, Or Master Hub, To Strike Gold Medals Or Coins?
High-precision CNC (Computer Numerical Control) machines play an essential role in the making of dies or master hubs to create gold coins or medals. Here is a brief outline of the CNC Programming Process.
A CAD program (Computer Aided Design), creates a 3D model of the design that is used for a coin.
The CAM (Computer-Aided Manufacturing) software generates toolpaths as well as instructions for CNC machines based on the 3D model.
How to choose the right Die Material
CNC machined of the master hub and die makes use of robust, high-quality, durable materials such as brass, steel or hardened metals. These materials can withstand the extreme pressure striking process, and guarantee precise reproduction of the design.
Fixtures and Setup
The material chosen is then secured to the worktable of the CNC and vice or vice to ensure precise machining. It is crucial to prevent the material from moving and vibration during processing.
CNC Machining Process-
CNC machines use cutting tool such as ball mills or end mills to cut the design in the hub master or die.
The CNC machine is used to remove material from blocks of material that are blank in accordance with the 3D specifications.
Different sizes of cutting tools and types can be used to create different depths, contours and details on the medal or coin.
CNC machines have computer-controlled algorithms that regulate their movements and provide precision as small as micrometers.
Finishing and refinement
After the initial machining, the hub or die is subject to the process of refinement.
The surface finish needs to be smoothed, polished, and then crafted by hand or with specialized tools.
Quality Control and Inspec-
To ensure precision and conformity to the design specifications The die or master wheel is subjected to rigorous inspection. Tools for measuring such as gauges, micrometers or optical measuring instruments are used.
Treatment for Hardening (Optional)
Certain dies may undergo additional treatments like surface or heat hardening to improve the durability and resistance to wear during the striking process.
CNC machines are able to reproduce intricate designs precisely using master hubs and dies. Die dies offer the required tools to make gold coins or medals in a consistent manner in a precise and precise manner, as well as with precise detail.

Based on their knowledge, they can add intricate detail and fine-tune the design. Check out how they achieved this Evaluation of Working Hub.
The engravers first look at the hub or die that was created from the original hub by Janvier. They examine the transfer's quality and the depth.
Correction of Imperfections
Engravers can correct any inconsistencies or imperfections within the transfered design. They may use precision tools to correct small errors, modify depths, or refine certain elements to ensure uniformity and accuracy.
Enhancing Details
Engravers can add fine specifics to a design by using specialized engraving equipment such as burins and pneumatic engraving machine. They make use of special tools for engraving to add elaborate details.
Dimensional Enhancement and Depth
The engravers alter the depths and contours the design in order to create dimension and depth. This process involves skillfully varying the cut's depth to emphasize specific elements and give a sense of realism or texture.
Texture and Finishing Touches-
Engravers can improve the visual appeal by adding textures and finishes to particular areas of the design. Effects and textures on surfaces can be created using techniques such as frosting, stippling or other types of shading.
Quality Control and Inspection
Engravers undergo frequent checks and inspections during the engraving process to ensure that the final design is in line with the standards for precision, clarity and aesthetics.
Collaboration and artistic interpretation-
Engravers frequently work closely with artists, designers, or other creatives to interpret a design accurately. Their artistic interpretation and skills can elevate the designs by adding subtle nuances, or refining specific details according to artistic vision.
Engravers who possess exceptional skills are recognized for their accuracy and artistic skills in manipulating metal surfaces. Their dedication to detail and careful workmanship enhances the appearance of gold coins or medals and ensures that the final product meets with aesthetics and the highest quality standards.

Gold plating and Gilding: Coins and gold medals can be plated using a thin gold layer. This adds a luxurious appearance to the piece or medal.
Aesthetic Effects
Patina or Antique Finishes - Chemical or special coatings can be used to create an antique finish. This gives depth and character to the design, by creating an aged, oxidized appearance.
Coloring or Colorization - Certain metals or coins are colored in specific areas with the help of coatings, enamels or other specialized coatings. These colors can be used to highlight particular design elements or make a contrast.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions - For coins or medals that have intricate designs or surfaces susceptible to tarnishing, anti-tarnish coats or solutions can be applied. These coatings prevent oxidation or discoloration of the surface of the metal over time.
Specialized Coatings for Security or authentication
UV-Reactive Coatings and UV-Reactive Coatings and Coatings: Some coins or medals are coated with coatings that contain UV reactive, which reveal encrypted elements or hidden components for security purposes or authentication.
Selective Coatings to Enhance Contrast
