How Do High-Precision Cnc Cutting Machines Cut Designs Into Master Hubs Or Dies For Striking Gold And Silver Coins?
When it comes to the creation of master hubs (or dies) to make gold coins or medals CNC machines that have high precision are crucial. Here's a brief introduction to CNC Programming.
The CAD (Computer-Aided Design) software is used to create a 3D representation of the medal or coin design.
CAM (Computer Aided Manufacturing), software that creates toolpaths, instructions and commands for CNC machines built on 3D models.
The selection of Die Materials
For CNC processing, such as the master hub or die, which is durable and high-quality materials such as brass, steel or even alloys that have been hardened will be utilized. These materials are resistant to the high-pressure hitting process and ensure a precise reproduction.
Fixture and Setup
The selected material is fixed onto the CNC machine's worktable or vice for accurate machine. The correct fixing of the material is vital to stop the material from moving and vibration during machining.
CNC Machining Process
CNC machines use end mills and ball mills for cutting tools to carve designs into dies or master hubs.
The CNC machine follows the programed toolpaths, carefully removing material from the blank block in accordance with the 3D model's specifications.
Cutting tools can be of various sizes and types to create different depths, shapes and designs on a medal or coin.
CNC machines are equipped with computer algorithms which control their movements and provide accuracy as low as micrometers.
Refinement and Finishing
The master hub, or die, is refined.
Polishing, smoothing, and detailing with a hand-held device or using specialized tools ensure the surface finish meets the standards required.
Quality Control Inspection and Testing
To ensure accuracy and conformance to the design specifications The master wheel or die is put through a thorough examination. Tools for measuring such as gauges, micrometers and optical measuring instruments are used.
Treatment and Hardening (optional)-
Die dies could be treated using heat hardening or surface treatments to improve durability and wear resistance during the striking process.
CNC machines can provide the accuracy and precision required to replicate intricate designs on master hubs or dies. Die dies offer the required equipment to create gold medals or coins consistently in a precise and precise manner, as well as with fine details.
