Diamond Wire Drawing Die Blanks

As one of the abrasive powdermanufactures,E-Grind supplies all types of diamond powdersincluding Resin bond diamond, Metal bond diamond, Saw Grit and Wheel Grit. Diamond mesh grit are used to make grinding wheels for cutting and grinding process. Diamond micron is for lapping and polishing. Saw Grit is the strongest diamond, designed to meet the requirements of the stone processing in construction and ceramic industries, frequently used in Titanium cladding version to enhance the bonding; wheel grit is in sizes from 70/80 to 325/400, mainly for Metal bond and electroplating bond tools.

Grind is one of theprofessional wire drawing dies suppliers and diamond dies manufacturers, we provide two series of PCD wire drawing die blanks: CDB Series and TDBY Series. 5 grades of grain size available: 3 microns, 5 microns, 10 microns, 25 microns and 50 microns.

What is PCD Wire Drawing Dies Used for?

The diamond wire drawing dies/diamond drawing dies blank is made by sintering diamond micropowder under the action of various metals (containing cobalt) catalysts using ultrahigh temperature and ultrahigh-pressure processes. During the sintering process, high-strength diamond bonds are formed between the diamond microcrystalline particles, and the diamond fine powder particles are strongly combined to form polycrystalline diamond (PCD). The diamond wire drawing die blank manufactured by this method has high wear resistance, hardness and thermal conductivity, but also has good mechanical strength and toughness. It is suitable for drawing copper, aluminum, nickel and other non-ferrous metals, stainless steel and various alloy wire.
