The CAM software (Computer Aided Manufacturing) generates instructions and toolpaths for CNC machines by using a 3D model.
The Selection of Die Material
CNC machining is carried out on dies or master hubs made of durable and high quality materials such as brass, steel, or alloys that are hardened. These materials can withstand the extreme pressure striking process and ensure precise replication of the model.
Fixture and Setup
The material chosen is then securely mounted onto the CNC's worktable vice or worktable to ensure precision machine. It is essential to avoid any movement or vibrations during the machining.
CNC Machining Process
CNC machines employ cutting tools such as ball mills or end mills that cut out the design in the hub master or die.
The CNC machine utilizes the tools that are programmed, and removes the material in a precise manner from the block of material in accordance with the 3D specifications of the models.
Cutting tools are available in different sizes and types to create different depths, shapes and designs on medals or coins.
CNC machine moves are controlled by a computer algorithm, which ensures accuracy down to micrometer levels.
Refinement and Finishing
After the initial machining is completed then the die or master hub undergoes further refinement.
The surface finish has to be polished, smoothed, and then crafted by hand or with tools that are specialized.
Quality Control and Inspection-
The final die, or hub is then subjected to a thorough inspection using the aid of measurement tools, such as micrometers, gauges and optical measuring instruments to ensure it is in compliance with the requirements of the design.
Treatment and hardening (optional).
Certain dies are heat-hardened or treated for increased durability and resistance to wear.
CNC machines can reproduce intricate designs precisely using master hubs and dies. Die machines are crucial for the accurate and consistent strike of gold coins, or other coins.
