LASER ENGRAVERS

RR Writer Series

This laser marking machine is 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 photoengraving, the laser marker is perfect for customizing metallic objects or precious alloys.

 

FEATURES

  • An integrated video camera facilitates the viewing of the laser marking area and ensures 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 1.5 mm - 2.0 mm thick metal plates, depending on the machine.

  • The cold light technology, thanks to the scarce generation of heat, eliminates the need for preheating the equipment and avoids 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.

  • 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.

Supports for Rings and Bracelets

Specially designed to be firmly applied to the rotary axis device, these three-pin chucks are perfect for laser marking the inner or the outer side of rings, bracelets, and items with a round shape. A special handling support on one of the pins of those chucks can be adapted to have large rings and rings exposing very large gems and stones micro-marked by laser.

Digitally Controlled Rotary Axis

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.

Automatic Feeder

The automatic feeder for metal plates provided by Orotig makes it possible to mark and cut objects from a metal sheet, without the need for 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 without the presence of an operator standing by.
