SUMIDIA WD

“SUMIDIA WD” is firmly bonded polycrystalline diamond developed through the use of our original ultra high-pressure sintering technology, which provides both strong and wear resistant wire drawing material.

• Characteristics SUMIDIA WD has stable quality superior to natural diamond.

Excellent breakage resistance Because of its firmly bonded polycrystalline structure, SUMIDIA WD eliminates the cleavage faults found in natural diamond.

Excellent wear-resistance SUMIDA WD offers superior wear resistance, uniform wear and excellent fracture strength.

High quality polished surface The homogeneity of sintered body is implemented in our original technology. The diamond content ratio in sintered body is increased and each diamond grain is firmly bonded. SUMIDIA WD has a high quality polished surface like natural diamond.

• Series SUMIDIA WD has 3 series such as with support ring, and with heat resistance

WD700

WD800 (Heat-Resistant type)

The WD700 series are self-supported die blanks. These blanks are suitable for all types of wiredrawing applications especially where cost-cutting is required.

The WD800 series are self-supported thermally stable blanks. These blanks are especially suited for applications which require high temperature in mounting and need high heat resistance in drawing.

WD900 The WD900 series are reinforced by a special outer ring. This feature makes it possible to draw not onlycopper and aluminum wire but high tensile steel wire as well.

• Grades

SUMIDIA WD HAS 5 GRADES: F, S, M, C, and E. • Available grades are limited by the shape and size

Grade

The F grade WD has a ultra fine diamond grain size. It is suitable for drawing dies that require a high quality surface finish or high fracture strength.

SUMICRYSTAL

“SUMICRYSTAL” is synthetic single crystal dia- mond which Sumitomo Electric succeeded in mass production for the first time in the world. “SUMICRYSTAL” is manufactured under severe quality control has stable quality, so it is suitable for industrial materials.

Synthesis of SUMICRYSTAL

Large high quality single crystal diamonds are synthesized under ultra-high pressure (50,000 atmospheres) and high temperature (over 1,300 ℃). The figure to the right shows the inside of an ultra-high pressure apparatus. A temperature gradient is created in the interior of the heater. This gradient is used to melt the carbon source into a molten solvent metal. This process allows the diamond to grow on a seed crystal. In order to accurately synthesize large high quality crystal, it is necessary to have purity materials and advanced technology for maintaining synthesizing conditions constant over a long period of time.

The inside of an ultra-high pressure apparatus.

Sumicrystal PD dresser blanks are single crystal diamonds processed into the shape of a long, thin prism. These Sumicrystals provide high precision dress- ing through reliable performance and long tool life.

PDX

Revolutionary Unique Shape The unique shape of the PD blanks gives the diamond consistent cross-section. This allows uniform diamond surface throughout the dressing process. The alongated shape also drastically reduces diamond pull-out. Characteristics

New Product with a Modified Face Orientation (1) Face orientation is a (211) face which increases life of the product (2) Abrasive resistance direction runs parallel with (111) face, facilitating setting of a blank when manufacturing dressers. Characteristics

Furthermore, the process of inspecting and selecting of crystals can be eliminated. (2) Excellent Fracture Resistance Cracking and fracturing of the diamond during wire drawing is greatly reduced. (3) Precise Crystal Orientation The top and bottom faces are in the (111) orientation and the degree of divergence in the orientation is less than 1 ° . This is a major determinate of die life. (4) Grinding is Not Necessary Because the top and bottom faces are made parallel by cleavage, further grinding is eliminated.
