25mm Laser Process Heads

Optical Laser Wrist : OLW-25

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.

Auto-Focus Profile / Bevel Cutting Laser Process Head (OLW-25-AF)

Designed for dynamic surface tracking using the CHS-8000 Auto Focus 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.

OLW-25-AF Features

• ±10mm travel with limit Center Position Sensors
• 90º Mirror Design
• Floating Mount
• X-Y-Z Axis Adjustable Focus Lens Cell with Collar Mounted Process Head
• Rated up to 18 Bar (265 PSIG)
• Translation Speeds of 100mm (4.0")/Sec
• Several Focal Lengths and Nozzle Tip Designs Available
• Available in 25mm for Nd:YAG or CO2 Applications

Parabolic Welding / Cladding Laser Process Head (OLW-25-PW)

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.

OLW-25-PW Features

• Parabolic Mirror Design
• Floating Mount
• Several Focal Lengths & Nozzle Tip Designs Available
• Manifold Purge Gas Nozzle & Air Knife Option
• Available for CO2 Applications
