The right PCD dies for Cu and Al rod breakdown machines

摘要

Temsa Diamond Die Division SA, Spain, specialises in the manufacture of diamond dies and tools for the cable and wire industries. The company's manufacturing programme covers natural diamond (ND), synthetic monocrystalline (MCD), and synthetic polycrystalline (PCD) wire drawing dies, extrusion dies and cable guides for cable coating, and special dies in PCD for pipe calibration and cable compacting. There is a common discrepancy between the actual possibilities of PCD blanks and the so called 'maximum recommended bore size' proposed by the PCD blank manufacturers, particularly in the design of sets of dies for the Cu and Al rod breakdown machines.
