Optical Laser Wrist

Designed for multi-axis gantry laser processing machines, laser robots and custom equipment. For profile/bevel cutting, welding/cladding and drilling applications. Each system is custom assembled as per customer specification. Available in 25mm or 50mm clear apertures for either CO2 or Nd:YAG applications.

Dual axis wrists feature two floating mirror mounts in a sealed beam delivery system, collective junction box for electronic and fluid connections and an electrically-interlocked quick-disconnect magnetic coupler designed to accept various process head styles. Internal crash protection breakaway mechanism. Contains proximity sensor position limits on both axis of rotation.

Optical Laser Wrist (OLW) Attachments

A large variety of attachments are possible with the Optical Laser wrist. Below are some examples of attachments we have created before. The images above contain renders and pictures of these attachments.

• Standard Cutting & Drilling Head
  • For use when the programed tool path and surface features are accurate enough to maintain laser focus without the need for dynamic tracking.
• Auto-Focus Profile / Bevel Cutting Laser Process Head
  • Designed for dynamic surface tracking using capacitive height sensing electronics. The +/-10 mm ability to locate the laser focus precisely on the actual part is used to compensate for complex geometry where surface features may not be to print or the programed tool path of the machine it is installed on.
• Parabolic Welding / Cladding Laser Process Head
  • The welding process is normally less demanding on the location of the laser focus, where the programmed tool path is all that is required to maintain process parameters.
