• Allows the hardening of complex and variable components in power-train and hardening applications.
• Variably adjustable process parameters: track mid-point; track width left and right; pre-heating and hardening temperatures and power; defocussing; and emissions coefficient. Parameters can also be changed during the process.
• Reliable hardening and quality: made possible by the highly dynamic temperature control mechanism via the variable scanner mirror speed and subsidiary slow laser power controls (based on Patent EP 08 022 027 B2).
• Significantly reduced set-up time; process can be easily adapted and adjusted; the optional auto-focus module allows spot diameter to vary without requiring a change to the operating clearance.
• By using scapacs^® components, the optical system can be optimally adapted to the laser source and the process parameters (fibre diameter, laser source, required power distribution).
• Optionally, a monitoring camera can be integrated into the system.
• Optionally available with external line projector so that operating clearance can be optimally set.

Variable fibre coupling

• Trumpf-D
• Trumpf-B
• Optoskand QBH
• Optoskand MMI

Collimation

• Fixed collimation or with integrated auto-focus module.
• The auto-focus module allows the focus diameter to be modified based on the process. The stand-off clearance to the component does not need to be adjusted.
• An additional safety glass under the end of the glass fibre prevents contaminants from penetrating while the fibre is being changed.

Pyrometer

• Integrated camera-based pyrometer.
• The path of the pyrometer measurement beam is coaxial with the path of the laser beam.
• Thus the scanner also moves the pyrometer’s measurement field.
• The measurement distance from the pyrometer to the laser focus is constant which allows it to be optimally adjusted.
• An error in the scanner positioning does not affect the measurement result.
• Temperature fields can be selected using software functions. No mechanical adjustment of the sensors is required.

Monitoring camera

• Integrated coaxial-aligned monitoring camera; camera observation is independent of the position of the scanner mirror.
• Thus the component remains still for the observer (this is not the case for the pyrometer camera).
• The location of the hardening track can be checked easily and securely using the camera.
• So the initial commissioning process is faster and less prone to errors.

Scanner unit

• Highly dynamic scanner unit.
• 1-D linear projection.
• Variable programming options for the scanned line  (wide left, right and centre position).
• External cooling for the entire optics and the scanner unit. This prevents the penetration of cooling water into the optical system.

Flange mounting on the robot

• Can be quickly swapped out with high-precision tool coupling.
• Measurement for the optics, just as for all scapacs^® devices, is enabled at the appropriate measuring stations.

Safety glass drawer

• Dust-proof drawer for safety glass.
• Additional protective glass between the lens and the safety glass drawer: offers extra protection for the focusing lens.
• Efficient cross-jet module (not shown here).
• Process jet uses nozzle from Silvent (not shown here) in order to prevent water vapour from the quenching bath from reaching the optics.

Controller

• Modern, bus-based control strategy.
• Actuators and sensors are bus nodes.
• The RLH controller is the bus master and is separated from the RLH processing head.
• Controller can be installed as needed (for example, in the facility’s equipment cabinet).
• The RLH system can communicate with the production facility on different Fieldbus types, such as Interbus, Profibus, Devicenet or Profinet.
• A facility PC can be used for parameterization.
