GRADES
EHWA GRADES ( Tool Materials)
In today's modern industry, we're pushing the boundaries of new materials and precise machining. As we improve our production processes and tackle challenges with machining advanced materials, there's a growing need for cutting tools that go beyond the usual options like high-speed steel or ceramics. Polycrystalline Diamond (PCD), a synthetic diamond product produced by sintering selected diamond particles with a metal matrix, utilizing advanced technology for precise temperature control and high-pressure conditions.
