Turnkey Laser System Design for Machining Thermally Stable Diamonds

Precision MicroFab™ designed, manufactured and installed an entirely new production-level laser system to drill diamond carbide and thermally stable diamonds. This system replaced a legacy system and considerably reduced run time per part, increasing the daily productivity by a factor of three. This is just one example of our custom laser manufacture capability. We will custom tailor a laser system specifically for your application.

Highlights of the System’s Features and Benefits:

  • Aerotech stages and amplifiers.
  • A top of the line computer with the latest motion control software.
  • Rock-solid Fiber laser technology.
  • Air-actuated collet spindle with less than 0.00005” TIR, driven by an Aerotech motor.
  • Beam delivery integrated with video microscope and optics mounted on the stages. Optics and beam delivery module retracts for safe and easy part loading and unloading.
  • Applications specific custom motion controls.
  • Extremely compact machine base footprint of 28” by 26” plus monitor and keyboard arm.
