Abstract
Skeleton matrix W-Co bonded diamond dicing blade was fabricated by using a doctor blade method and sintered by PECS (Pulsed Electric Current Sintering) method. Fabricated dicing blade shows 2 times higher cutting speed than commercial dicing blades on 3.2 N applied force cutting test with using Al2O3·TiC as a cutting material. Commercial dicing blade shows decrement of cutting speed, because of the decrement of the diamond grains and their protrusion height. Fabricated dicing blade surface was kept the diamond grains and their protrusion height even though after 750mm cutting.
