The software CAM (Computer Aided Manufacturing), creates the toolpaths and directions for the CNC machine based on the 3D design.
Select the correct material to cut dies
CNC machining dies and master hubs are performed on tough materials such as brasses, steels, and alloys that have been hardened. These materials are able to endure high-pressure strikes and provide precise reproduction of the design.
Fixtures and Setup
The selected material is fixed onto the CNC machine's worktable or vice for accurate machine. It is crucial to prevent any movement or vibrations during the machining.
CNC Machining Process
CNC machines use tools such as endmills or ballmills to engrave the design on the master or die.
The CNC machine removes material from the blocks of blank material in accordance with the 3D specifications.
Different types and sizes of cutting tools are used to attain different dimensions, contours, and the details of the medal or coin design.
CNC machine movements are controlled by computer software, which guarantees precision to the micrometer level.
Refinement and Finishing
Once the initial machining is completed then the die or master hub is further refined.
The surface finish has to be smoothed, polished and crafted by hand or with specialized tools.
Quality Control and InspectionQuality Control and Inspec
The finished die, or master hub, can be examined with precision using tools such a micrometers. gauges, and optical measuring instruments.
Treatment and hardening (optional).
Some dies are subjected to further treatments like heat hardening, surface treatments and even heat to improve the durability during the process of striking.

What Is The Reason Why Dies Used To Strike Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
The process of vacuum hardening used to create dies that strike gold medals or coins involves placing the dies in extreme temperatures and controlled conditions in a vapor furnace. This article will provide an overview of the procedure for die preparation and Cleaning-
Diets for striking medals or coins are cleaned and free of any contaminants.
Moving into the vacuum furnace
Die dies can be inserted in a vacuum oven that creates a vacuum within the heat-treating area.
Evacuation by Airplane
The vacuum furnace removes air from the room, forming an environment of controlled vacuum that is free of oxygen or other gases. This ensures uniform heating and prevents the oxidation process from occurring.
Heating Phase-
The furnace is heated to the desired temperature in order to harden the dies. The temperature range will be determined by the type of material and the process of hardening.
Soaking at High temperatures
The dies must be held at the high temperature for a specific duration to allow the material to reach and maintain its desired hardness.
Cooling or quenching
The dies will be immediately cooled off or quenched following the soaking. This rapid cooling process helps keep the desired toughness and durability of the material.
Tempering Optional
In certain cases, hardening is then followed by a tempering process. Tempering involves heating dies at a low temperature in order to relieve internal tensions and increase durability.
Quality Control & Inspection
Die dies that are hardened undergo rigorous quality inspections and tests to ensure they meet standards for strength, hardness and tolerances for dimensional dimensions.
Post-Treatment Handling-
The dies will be subjected to further processing including coating or polishing, prior to being used for the coin or medal striking.
The process of hardening by vacuum increases the wear resistance, durability and life span of dies used to make gold medals or coins. In ensuring a safe and contaminant-free environment, this process provides an efficient and consistent method to make the dies harder.
