  • Drawing Die Laser Drilling System compact and solid constructed
    Compact design within a minimum of space

  • To obtain very smooth surfaces, the machine uses different drilling strategies.
  • Depending on the finish qualitiy, the typical drilling time for a diamond die with 0,2 mm in diameter lies between 30 seconds and 4 minutes.
  • In the rapid drilling mode, larger PCD drawing dies (e.g. drawing dies with a diameter of 1 mm and a height of 2.5mm) can be drilled within 10 to 12 minutes.
  • The accuracy of the created drawing angle is within the +/- 1° tolerance field.
  • If the heights of the diamond insert are varied, the program provides a constant reduction length, thus considerably reducing the drawing dies´s postprocessing.
  • All drilled drawing dies are recorded in Log-files.
  • The machine is suitable for 24/7 operation


  • Diode pumped Nd:YAG laser with high beam qualitiy, ground mode resonator, Q-switched pulsed 1-Hz to 10-kHz, optimized laser pulse length and pulse peak power to remove natural diamond, ultra-stable laser resonator, recommended room temperature 18 to 25°C
  • External supply 1.5 kW, 230 VAC, filtered compressed air 6 bar, water cooling between 18 and 22°C
  • Hard stone test plates for the laser resonator and for all positioning tables
  • Triaxial DC precision tables with resolutions of up to 0.1 µm
  • Precision rotary measuring table for double-sided angle drilling of front and back in one setting
  • No offset between the drawing die´s drawing and exit cone
  • Air-cushioned precision rotary table with collet chuck for drawing dies with mount diameters between 25 and 30 mm and a concentricity better than 1 µm
  • 8- axis CNC controller with a 0.1 µm resolution
  • Automated measuring of the diamond´s position and height
  • Integrated pneumatic transport system for approx. 120 drawing dies
  • Magazine for mount diameters from 20 to 30 mm
  • Height of mount from 6 to 15 mm
  • Laser safety class one due to closed system with laser protection window
