The WSD-K2 is the first small-scale wire saw from Takatori. Designed for R&D and limited pilot production, the WSD-K2 uses diamond wire to slice workpieces up to 156mm in diameter using 1 to 10 wires. The machine is popular for diamond wire process development, and is used for materials like sapphire, SiC, glass, and more. The physics department at the University of California Santa Barbara use the WSD-K2 to slice bulk crystals of GaN grown by Nobel prize-winning physicist Shuji Nakamura.
