Gold and silver jewelry engraving can be done by CNC engraving machines, laser engraving, or hand engraving. Today, CNC engraving is the most efficient and precise method for modern jewelry production.
1. Design Preparation
Create or import the jewelry design using CAD software. Patterns, logos, text, or 3D relief designs are prepared and converted into machine engraving files.
2. Material Preparation
Cut and polish the gold or silver jewelry blank. Fix the ring, bracelet, pendant, or plate securely on the CNC machine fixture to ensure stability.
3. Machine Setup
Select engraving tools (diamond tip, carbide cutter, etc.)
Set engraving depth, speed, and path
Test on a sample piece if necessary
4. CNC Engraving Process
The CNC jewelry engraving machine follows the programmed path to carve the design onto the metal surface with high precision. This step ensures consistent quality and fine details.
5. Cleaning and Polishing
After engraving, remove metal dust, clean the jewelry, and polish the surface to improve brightness and smoothness.
6. Quality Inspection
Check engraving depth, clarity, and finish.
Make adjustments if needed before final packaging.
If you're looking for one or several types of jewellery CNC engraving equipment, here we list some of the common CNC engraving solutions used in jewellery manufacturing.
