01HSA5 series 

Winbro Group has installed over 250 of the acclaimed HSD series machines across the world into the most advanced aerospace and land based gas turbine industries. Developed from the original specification for these machines, the HSA5-III encompasses the latest design, control and process concepts. Enhanced features of the machine include:

  • Windows 7® based operating system
  • Patented Part Probing
  • Integration of a range of fiber based lasers
  • Winbro LaseMill software

02Machine Overview 

The HSA5-III is built upon a robust fabricated steel base which is welded, stress relieved and machined.

A fabricated column, mounted to the rear of the base carries the Z axis, on to which is mounted the integrated laser scanning head. The “X” and “Y” assembly is mounted on machined pads at the front of the base. The A / B rotary / tilt table is mounted directly to the X-Y table, and driven by torque motors.

03Laser Ablation Process 

HSA5-III machine uses a fiber laser which delivers 50 - 100 Watt of average power, pulsing through a Q-switch at up to 100kHz. A Galvo-Scanning head is used to move the beam on a programmed path with a typical focal length of 163mm (6.4”) and the laser spot size of approximately 75 microns (0.003”).
