An open-frame marking machine sitting on a jewelry bench raises three problems at once: dust and fine metal particles spread across the room, the operator is exposed to stray laser reflection from polished precious metal, and any gold removed during engraving is swept up with the vacuum instead of returning to the workshop. An enclosed benchtop unit addresses all three in one cabinet. The machine covered in this guide is a sealed fiber laser engraving platform with a 300 × 300 mm marking chamber, laser power options from 20W up to 200W, a maximum deep-carving depth of ±5 mm and a documented cut capability of up to 2 mm — built mainly for gold, silver and brass work in commemorative coins, pendants, rings and bracelets. Below you will find how the cabinet is built, what the laser can do to high-reflective noble metals, how CCD vision changes batch marking, the full specification table, and a checklist for evaluating an enclosed jewelry laser before you commit.
What Is an Enclosed Benchtop Laser Engraving Machine?
It is a Class-1-style enclosed workstation: the laser head, the galvanometer scanner and the workpiece all sit inside a sealed cabinet, and the operator works through a protective viewing panel rather than standing in the open beam path. In this model the marking chamber sits under the top-mounted optical unit, and the workpiece platform is inside the chamber, so the maximum marking field of 300 × 300 mm is contained within the enclosure instead of spreading across the bench.
The cabinet is built around the following elements, each marked on the product diagram:
- Large marking chamber with a maximum marking field of 300 × 300 mm
- Green transparent acrylic viewing panel — OD7+ protective PMMA available as an option
- OD7+ laser protective class enclosure rating
- Anti-collision safety sensor with high sensitivity on the door path
- Motorized door with membrane button control
- Dustproof plate that stops metal debris from falling into the equipment
- Spare side doors for service access and fixture changes
- Handle and foot pads for repositioning the unit as a benchtop machine
Machine size is listed at 900 × 600 × 745 (1,000) mm, so it occupies a dedicated bench or a floor-level stand rather than a corner of an existing work table. Up-and-down adjustment of the Z axis is electric and driven from a button, which matters once you are changing between flat plates, ring fixtures and deeper relief work several times a day.
One Cabinet, Four Jobs: Marking, Engraving, Deep Carving and Cutting
Most marking machines do one thing. This platform is specified as a precious metal solution that covers four operations without changing machines:
| Marking | Logos, purity stamps, serial numbers, dates and personalised text on gold, silver, brass, stainless steel and plastics |
|---|---|
| Engraving / embossing | Relief work on coins, pendants and medallions |
| Deep carving | Depth of ±5 mm for three-dimensional relief and deep relief lettering |
| Cutting | Documented cut up to 2 mm, for pendant outlines, charms and pierced designs |
For gold, silver and brass sheet the product documentation lists a thickness range of 1 mm to 5 mm, with a documented maximum cut of 2 mm — the detail page illustrates this with a caliper reading of 2.02 mm beside the caption "Can be cut to Max 2mm". If your production involves sheet outside the documented range, send us the exact alloy and thickness before ordering so we can confirm what the machine will achieve on your material rather than relying on a table value.
Working with High-Reflective Noble Metals
Gold, silver and polished brass are the hardest common materials to mark safely, because a mirror-like surface sends a large part of the beam straight back up the optical path. Two design choices in this machine are aimed at that problem:
- Germany Scanlab galvanometer fitted with special protection for high back reflection, so the scanner head tolerates reflected energy from polished noble metal.
- Sealed chamber geometry, which keeps reflected light inside the enclosure rather than into the room.
The focused materials are listed as gold from 9K to 24K, silver from 925 grade to pure silver, and bronze of all varieties. That range matters in practice: 9K and 18K alloys, sterling silver and pure silver all behave differently at the same power setting, and a machine that is stable across the full range saves you from re-tuning every time the alloy changes.
CCD vision for batch work on small parts
The optical system supports a CCD visual function that lets batch marking be set directly on the computer interface. Instead of aligning each small workpiece by eye against a fixture, the operator positions the batch on screen and the software handles the pattern placement across the array. For rings, small charms and other components that are hard to clamp repeatably, this shortens setup and reduces the scatter that comes from manual alignment.
Laser Power Options: 20W to 200W from the Same Platform
The model is offered with fiber laser sources at 20W, 30W, 50W, 60W, 100W and 200W, using Raycus, Max, IPG or JPT sources depending on configuration. Beam quality is specified at M² ≤ 1.4, the wavelength is 1064 nm, and the fiber laser module is rated for a 100,000-hour life span. Cooling is air-based, which means no water chiller and no chiller maintenance on the bench.
Which power you need depends on what the machine has to do more of:
- Marking and marking-plus-light-engraving — lower power options handle logos, purity stamps and serial numbers on jewelry, including the fine work that the 0.03 mm minimum line width and 0.2 mm minimum character rating are there for.
- Deep carving and cutting — the ±5 mm deep carving and 2 mm cut figures are the headline capability of the higher-power configurations, since removing material rather than changing its surface needs more energy per unit of time.
- Mixed production — most jewelry workshops run both. In that case the decision is usually made on the heaviest job in the schedule, not the average one.
Note that the detail page also carries a "Laser power: 1KW~3KW" line inside its thickness-range block, which belongs to a different machine family and does not match the specification table; the specification table — 20W through 200W — is the authoritative figure for this model.
2D, 2.5D and 3D: Focus Options and Precious Stone Marking
Focus control is where an enclosed laser earns its keep on curved and relief work. On this model, 2D, 2.5D and 3D auto-focus are available as options, allowing the focal plane to follow the surface instead of assuming a flat workpiece:
- 2D — flat surfaces: plates, coin faces, tags and sheet stock.
- 2.5D — partial relief and shallow curvature, common on medallions and stamped jewelry.
- 3D — continuous depth variation, for domed surfaces and full three-dimensional relief engraving.
A UV laser source is also available as an option for precious stone marking, which extends the machine beyond metal for workshops that set and finish stones in the same shop. Confirm the configuration you need at the quotation stage, since these are build options rather than retrofits.
Safety, Containment and Gold Recovery Inside the Cabinet
The reason to choose an enclosed machine over an open one is mostly downstream of the marking itself.
Operator protection
The enclosure is rated to OD7+ laser protective class, with a green transparent acrylic viewing panel so the operator can watch the marking process directly instead of using a camera feed. OD7+ protective PMMA is offered as an upgrade for the panel. An anti-collision safety sensor with high sensitivity sits on the door path, and the door itself is motorised with a membrane button, so the chamber cannot be opened mid-cycle in normal operation.
Material containment and recovery
The cabinet and its internal parts are sealed for the collection and recycling of gold. Combined with the dustproof plate that stops metal debris from falling into the equipment internals, this is the practical difference between an enclosed jewelry laser and an open marking head: the precious metal you remove stays inside the machine where it can be recovered, rather than spreading across the bench and the floor. For a workshop processing gold daily, recovered material offsets a meaningful part of the machine's running cost over its service life.

Free Accessories, Standard Configuration and Installation
The machine ships with a free accessory set that covers the items needed to start safely: spare protective panels for the work area, a full hex key set for maintenance and fixture changes, and a pair of laser safety goggles. Optional equipment includes the automatic plate feeder and cutter, the OD7+ protective PMMA panel upgrade, the 2D / 2.5D / 3D auto-focus system and the UV laser source for precious stone work.
Installation is a benchtop or stand-mounted job. Confirm the AC supply matches the 220V / 50–60 Hz / 10 A input rating, allow clearance around the 900 × 600 mm base for the side doors and the feeder if that option is fitted, and set the machine on a level surface using the foot pads. The sealed chamber means no external fume extraction ducting is required for the enclosure itself, but the dustproof plate should be checked and cleared as part of routine maintenance so that collected debris does not build up inside the cabinet. Our application team provides online video guidance for parameter setup, so marking and cutting parameters can be tuned on your own parts rather than guessed from a table.
Frequently Asked Questions
What is the maximum marking area on this machine?
The maximum marking field is 300 × 300 mm, contained inside the sealed marking chamber. That is the largest field in the range and covers coin blanks, pendant sheets, multiple ring fixtures and batch arrays of small components in a single run.
Can it cut as well as engrave?
Yes. The platform is specified for marking, engraving, deep carving to ±5 mm and cutting up to 2 mm. The detail page documents the cutting capability with a caliper reading of 2.02 mm. For sheet outside that range, confirm the alloy and thickness with us before ordering.
Which gold and silver alloys does it handle?
Gold from 9K to 24K, silver from 925 grade to pure silver, and bronze of all varieties. High-reflective noble metals are handled by the Germany Scanlab galvanometer, which is fitted with special protection for high back reflection.
Is the machine safe to operate without a separate laser safety enclosure?
The machine is itself an enclosure, rated to OD7+ laser protective class, with a green transparent acrylic viewing panel (OD7+ protective PMMA optional), an anti-collision safety sensor and a motorised door with membrane button control. Operators should still follow standard laser safety practice and wear the supplied safety goggles where the local assessment requires it.
How does the machine handle gold recovery?
The cabinet and internal parts are sealed for the collection and recycling of gold, and the dustproof plate prevents metal debris from falling into the equipment. Material removed during engraving and cutting is therefore collected inside the machine for recovery rather than dispersed into the workshop.
Can it mark precious stones as well as metal?
A UV laser source is available as an option for precious stone marking. It is a build option rather than a retrofit, so specify it at the quotation stage if your work includes stone marking.
How to Evaluate an Enclosed Jewelry Laser Before You Buy
Use this checklist when comparing enclosed machines, whether you are evaluating this model or another:
- Send your own alloy and thickness. 9K gold, sterling silver and pure silver need different parameters; a test on a competitor's sample tells you nothing about your own material.
- Test the deepest carve and the thickest cut you actually run. The documented ±5 mm carve and 2 mm cut are the limit figures, not the everyday settings.
- Confirm the field size against your largest part. A 300 × 300 mm field is what allows batch arrays and large pendant sheets without repositioning.
- Check the enclosure rating and recovery design. OD7+ protective class, sealed cabinet parts and a dustproof plate all affect long-term operating cost, not just safety compliance.
- Ask whether the focus option you need is a build option. 2D, 2.5D and 3D auto focus and the UV source are configuration choices, so they must be settled before the order is placed.
- Match the power to the heaviest job. The 20W to 200W range covers very different work; choose on the hardest task in your schedule.
