For jewelers, jewelry designers, and retailers, the choice of engraving machine is not always easy. Gravotech offers four dedicated jewelry engraving solutions: the M10 Jewel and M20 X Jewel mechanical machines, and the WeLase and LW2 laser engraving machines. This guide reviews the key criteria to help you find the best machine for your application, based on your level of expertise, budget, types of jewelry, marking aesthetics, materials, and work environment.
What Is Your Level of Expertise?
The first consideration is your current level of knowledge about engraving processes:
- New to engraving or using a subcontractor? Look for an easy-to-use machine like the M10 Jewel or the versatile M20 X Jewel.
- Currently engraving manually and want to modernize? Choose between the M10 Jewel and M20 X Jewel mechanical machines (quick to learn) or the WeLase laser machine (faster marking speed).
- Already own a rotary engraver and want more productivity? A jewelry laser engraver like the WeLase or LW2 offers speed, mass production capability, and greater return on investment.
What Budget for a Jewelry Engraver?
The criteria to consider include the initial budget, the current or future volume of production, and the cost of consumables and use. If you have a limited budget, mechanical jewelry engraving machines are affordable and become profitable more quickly. However, if you have a high volume of engraving, a laser engraver will give you more efficient productivity.
- M10 Jewel: Lowest initial budget. Low cost of use. Consumables include cutters and diamonds. Best for low production volume with quick ROI.
- M20 X Jewel: Moderate initial budget. Low operating cost. Higher consumable cost. Medium volume for quick ROI.
- WeLase: Moderate-to-high initial budget. Medium operating cost. Low consumable cost. High volume for quick ROI.
- LW2: Highest initial budget. Medium operating cost. Lowest consumable cost. High volume for quick ROI.
What Is Your Engraving Application?
Different machines are suited to different jewelry types:
- Rings and wedding bands only: The M10 Jewel is dedicated to bracelets and inside/outside ring engraving thanks to its integrated rotating device.
- Pendants, flat bracelets, and rings: The M20 X Jewel and WeLase are versatile -- they engrave cylindrical jewelry (rings inside and out), wedding bands, flat bracelets, and curved jewelry such as curb chains.
- Larger objects (metal cups, watch cases): The WeLase and LW2 laser engravers, as well as the M20 X Jewel rotary machine, can handle larger items.
What Kind of Marking Aesthetics?
The technology of the machine determines the aesthetic look. For a more authentic, tone-on-tone, and traditional look, a mechanical engraving machine is recommended. For a more contrasted rendering, a jewelry laser engraver is recommended. Laser machines can also perform fine cutting of precious metals (gold, silver) and produce high-resolution photo engravings.
- Engraving letters, numbers, symbols: All four machines handle this well.
- Fine cutting and contrasted engraving: M20 X Jewel, WeLase, and LW2.
- Photo engraving: M20 X Jewel, WeLase, and LW2 (not available on M10 Jewel).
- Engraving in color: All machines support this by adding colored products (wax, lacquer) after engraving.
Which Materials Can Be Engraved?
All Gravotech jewelry engraving solutions can engrave precious metals (gold, silver, gold plated, stainless steel, brass, bronze, copper) and plastic materials (acrylic, ABS). Mechanical machines produce a tone-on-tone rendering, while laser machines offer contrasted engraving. For organic and mineral materials (mother of pearl, glass, leather, wood, ceramic), the WeLase is the most versatile laser option. The M20 X Jewel also handles mother of pearl and glass.
What Is Your Work Environment?
Your working environment influences the machine choice:
- Workshop with limited space: The M10 Jewel (9 x 11.5 x 11.4 inches, 14.5 lbs) fits easily in tight spaces.
- In-store or at events: Opt for a versatile and transportable machine like the M20 X Jewel or WeLase. Both are compact and can be placed on a counter.
- E-commerce site: The LW2 laser station (23.6 x 24.5 x 30.4 inches, 132 lbs) is ideal for engraving larger parts, making serial markings, and increasing productivity with its semi-autonomous operation.
Focus: Rotary vs. Laser for Jewelry
Rotary Engraving
Mechanical engraving is the oldest technique. A rotating cutter hollows out the material for deep engraving, or a diamond scratches the surface for thin engraving. This offers a more authentic appearance, ideal for luxury jewelry and precious metals. It is the preferred choice for jewelers, jewelry designers, and costume jewelry dealers. Limitations include noise level (the cube on the M20 X Jewel reduces this) and non-contrasting results (requires consumables like paints or cold wax to add color).
Laser Marking
Laser technology locally heats the surface to create a permanent mark without removing material. It requires little maintenance, generates very little dust, and is much faster than mechanical engraving. Laser marking produces naturally black or white markings and allows photo engraving with quality rendering. It can also perform cutting operations up to 1 mm and deep markings up to 0.3 mm. Limitations include less depth than mechanical, higher purchase cost, and the machines are heavier and less transportable.
Software for Jewelry Engraving
Three software levels are available:
- Catalog: The simplest option. Pre-program engraving parameters for your product offering. Ideal for in-store use.
- ABC: For beginners. Set up an engraving in 3 simple steps: choose plate size, compose your engraving, and configure your machine.
- Gravostyle: The comprehensive package for experienced engravers addressing complex design, engraving, and cutting needs -- including photo engraving, batch production, and database communication for semi-automation.
Conclusion
A key step in the customization of jewelry is to acquire the right machine for your needs. Whether you are a beginner or experienced in engraving and cutting jewelry, the choice comes down to the types of jewelry you engrave, the volume of production, the aesthetic you desire, and your budget.
