Ultrasonic Disc Cutter

Ultra Sonic Disc Cutter


The ultrasonic disc cutter is used for producing 3mm diameter disks/rods of ceramic, metal, semiconductor and/or geological specimens for TEM analysis. The titanium cutting tool excursion is driven with a lead zirconium titanate (PZT) crystal at a driving frequency of 26 kHz. Boron or silicon carbide powder slurry is used as the cutting media.  


  • produces discs from materials as thin as 40 ┬Ám and cylindrical rods up to 10 mm length
  • uses an electrical continuity detector to automatically terminate the cutting process
  • site-specific sample positioning with 10um accuracy via integrated microscope attachment


  • Maximum sample diameter = 40mm
  • Hard materials (e.g. sapphire) exhibit very slow cutting rates
