CNC machines have changed how jewelry is made. They bring precision, repeatability and speed to a craft that was once fully manual. Yet the best results still combine technology with the hand of a skilled goldsmith. This guide explains how CNC machines for jewelry work, what they can do, and how to choose the right one.
What Is a CNC Machine for Jewelry?
CNC stands for Computer Numerical Control. In simple terms, the machine follows a digital design and removes material with rotating tools. So a ring, a bezel or a pendant starts as a CAD file and becomes a physical piece with micron accuracy.
Because the process is digital, it is repeatable. The hundredth piece matches the first. This is why both custom studios and mass producers rely on CNC technology today.

Main Types of CNC Machines Used in Jewelry
Not every machine does the same job. The jewelry industry uses a few key types.
CNC milling machines carve detailed designs from metal or wax. They shape complex patterns, settings and textures that are hard to reach by hand. For most jewelry work, milling is the core process.
CNC diamond-cutting machines use a diamond tool to cut bright, reflective facets. This is the “sparkle” you see on flashing rings and bangles. Because the diamond tool is extremely hard, the cut stays smooth and shiny.
CNC lathes produce symmetrical pieces. Wedding bands and bangles are typical examples, because they turn around a single axis.
The Faro angle: milling is the core process for most jewelry work, and diamond cutting adds the value-raising sparkle. Faro machines cover both, so one platform handles structure and finish together.
Which Materials Can CNC Machines Work?
CNC machines for jewelry handle a wide range of precious and technical metals. Gold, silver, platinum, titanium and stainless steel are all common. So designers can mix materials and expand their creative range without losing precision.
Each metal behaves differently. Platinum and high-karat gold are dense and valuable, so spindle speed, feed rate and tool choice must match the material. A good machine and a skilled operator manage this balance.
The CNC Jewelry Workflow, Step by Step
- Design. The piece starts in CAD software such as Rhino, Matrix or a dedicated jewelry program. Every size, border and fine detail is set here.
- CAM and toolpaths. The CAD file becomes machine instructions. Toolpaths decide how the cutter moves. Good toolpaths mean a clean finish and less rework.
- Setup and workholding. The operator clamps the raw metal and mounts the right tools. Stable workholding is critical for fine detail.
- Machining. The machine mills, cuts and engraves the piece. Multi-axis motion reaches angles a hand cannot.
- Finishing. After milling, the piece is deburred, polished and set with stones. CNC gets the part close; the goldsmith completes it.
“CNC gets the part close. The goldsmith completes it. Technology extends the craft — it does not replace it.”
CNC vs Traditional Jewelry Making
Hand fabrication and casting will always have their place. But CNC adds consistency, speed and repeatability. So for complex designs or batch production, CNC is often the better route. Many workshops combine both: CNC for the master and the structure, hand skills for the final finish.
How to Choose a CNC Machine for Jewelry
A few questions guide the choice:
- What do you produce? Rings and bangles favor compact multi-axis machines. Flat and sheet work favor stable milling platforms.
- Which metals? Harder and denser metals need rigid, vibration-free machines.
- What volume? Custom studios and mass producers have different needs for automation.
- What finish quality? Motion smoothness decides burr height and surface continuity, which shape the final polish.
Precision, stability and finish quality matter more than raw speed. A fast machine that leaves a rough surface only moves work to the polishing bench.
The Faro angle: the Faro F1 delivers high precision even on ultra-thin materials, while the Faro F35 Gold offers 7-axis flexibility for rings and bangles. Both pair with CAD-CAM workflows built for the trade.
The Faro Approach to CNC Jewelry
Faro builds CNC machines dedicated to jewelry and eyewear. The Faro F1 is a high-precision system for demanding work, stable even on ultra-thin materials. The Faro F35 Gold is a compact 7-axis machine for rings, bangles and fine jewelry, valued for flexibility and creative surface finishing.
Both platforms pair with CAD-CAM workflows built for the trade. So designers move from idea to finished piece in one controlled process. That is the point of CNC machines for jewelry: precision, repeatability and finish, together.
CNC technology has raised the bar for jewelry manufacturing. It does not replace the goldsmith; it extends the craft. With the right machine, the right workflow and skilled hands, CNC machines for jewelry deliver precision and beauty at scale.
