LASER Engraver RR-Writer 20W


The LASER-marker is a tool becoming almost indispensable to have in both the jewelry and industrial sectors. It is particularly useful for the marking of texts, logos, designs and graphic patterns. From serial numbering to photo engraving, the LASER-marker is perfect for customizing metallic objects or precious alloys.

Now in its third series, OROTIG’s LASER-markers have evolved, enhanced by a new range of power and automations: two new 20W models, 20W-S "Standard" and 20W-HQ "HighQuality", make it possible to reach new levels of quality and reducing significantly working time.

Based on MULTI-DIODE PUMPED FIBER technology, OROTIG’S LASER-generators guarantee the highest productive performance, capable of supporting even the most intense workloads, without compromising on the quality and precision, synonymous with highest quality standards.

This new and revolutionary technology assures extreme and long-lasting reliability, high energy efficiency, high productive performance.

Below are the main features of this new LASERmarker


  • An integrated video camera facilitates the viewing of the LASER-marking area, in order to position pieces better and to ensure total control during the marking phase.

  • An adjustable Z-axis facilitates the focusing of pieces in the marking area, thanks to the aid of two high clarity pilot diode-LASERs.

  • Powerful enough to cut up to 8-mm thick metal plates.

  • The "COLD-Light" technology, thanks to the scarce generation of heat, eliminates the need for pre-heating the equipment and avoid the use of auxiliary cooling devices.

  • Operating commands can be viewed and executed using either the machine’s control pad, or the software.

  • The possibility to import images, models, logos, texts etc., from a broad range of files with different extensions.

Rotary Axis Digitally Controlled All the OROTIG's Writers can be provided with a rotary device with automatic movement, controlled by software. A tool necessary for LASER-marking rings, bracelets and all round or curved objects. With its 1/500 scale precision, this device guarantees the perfect positioning of markings, even on particularly curved surfaces.
Supports for Rings and Bracelets Especially designed to be firmly applied to the rotary axis device, these three-pin chucks are perfect for LASER-marking the inner or the outern side of rings, bracelets and items with a round shape. A special handling support on one of the pins of those chicks can be adapted to have micro-marked by LASER large rings as well as rings exposing very large gems
Software for LASER-Marking Simple and intuitive, the software is able to import and export DXF, PLT, JPEG, BMP files and, thanks to an additional, optionally provided, extension, files from other more common CAM software. The software, translated into more than 50 languages, is an easy and immediate tool for the management of functions
Automatic Feeder for Plate Cutting The automatic feeder for metal plates provided by OROTIG makes it possible to mark and cut objects from a metal sheet, without the need of single manual positioning at each task. Fitted with pneumatic electro-valves and electronic movement controls via a console, it is able to re-position the metal sheet any time in need of without the presence of a standing-by operator.
3D Software Extension Ideal for the three-dimensional reproduction of designs and engravings with major detail, requiring different levels of engraving depth. This software extension, optionally provided, is based on the management of STL files, allows the 3D reproduction of solids authentic to their real proportions.
3 Axis Auto-Movement Axis position management through software, allowing the serial marking of multiple objects on the same tray and at the same time, even having different shapes and sizes. Based on the management of Cartesian coordinates, the use of this module, makes possible to program the movement of all axes depending on the position of the objects to be LASERmarked, making possible to boost productivity by the serial marking
Foot Pedal Control Once the design or the pattern or the job file has been selected and the marking parameters have been set for it, thanks to the control pedal, it is possible to repeat the same operation several times, without needing to re-interface with the software. The control pedal is a very useful tool for all those who need to repeat the same marking operation numerous times during the same production cycle.

The RR-Writer by OROTIG could also be fitted with a rotary axis device, to facilitate LASER-marking of curved surfaces, such as the inside or outside of rings or bracelets.

This Series of LASER Writers meets the highest standards of quality imposed by the most renowned producers of high-end jewelry. It is perfect for marking all types of precious and semi-precious metals, steel, titanium as well as many other materials, metallic and non.
