Wire Drawing Diamond Shaving Dies
Long Tool Life to Reduce the Setup Time and Waste Materials Diamond shaving dies are the best choice for wires needs excellent surface finish of cupper, aluminum, gold, titanium wires, compared to tungsten carbide or tool steel dies. ・Shaving dies are apply for shaving wire surface during intermediate process of wire drawing. ・Improve wire surface roughness and strict quality requirement. ・Depend on wire material, diamond shaving dies provide 20~100 times if compare with tungsten carbide shaving die. ・Reduce set up time, wire material loss because of long die life. ■Features ・Shaving copper wires, Aluminum wires, Gold wires and Titanium wires ■Applications
What are Diamond / CBN?
Diamond
Diamond comes from the Greek word "adamas" (a thing hard to be conquered) and became “Diamond" in the middle of the 16th century. The Japanese name is Kongoseki. It is a mineral made of pure carbon, generally known as a gem. Because it is the hardest among natural substances, it is also used for industrial applications. Approximately 80% of all natural diamond is used for industrial applications; nearly all artificial diamond is for industrial applications. Synthetic diamond, also called artificial diamond, is diamond artificially created using carbon materials. The synthetic diamond is mainly produced by high temperature, high pressure synthesis (HPHT) or chemical vapor deposition (CVD). Synthetic diamond is far inferior to natural diamond in terms of transparency and radiance. In addition, it is greatly inferior in terms of beauty derived from diamond’s refractive index of light. Synthetic diamond, therefore, is mostly used for industrial applications.
Diamond Compacting Dies
Synthetic Diamond (Sumitomo Electric Industries, Ltd. Sumicrystal)
Excellent Wearing Resistance, Stable Weight Per Size and Length Compacting dies are tools to strand conductors and at the same time, compact them to a circular shape and are used for power cables and automotive low voltage wires (wire harness). We offer a wide range of sizes to meet your applications by polycrystalline material and applying our advanced machining technology. ・Compacting dies are tools to compact the conductor to a round shape. ・Outstanding wear resistance assures production of wire products of a consistent size and weight pre unit length. ・The long tool life reduces setup time and wire material loss due to die replacement. ・Stable wire diameter leads to the cost reduction of insulation. ・Can get stable surface quality. ■Features ・Stranded wires of power cables, Automotive wire harnesses, Wire ropes ■Applications
CBN
CBN is an acronym for “Cubic Boron Nitride” constitute of boron and nitrogen. CBN has the high hardness of diamond. Compared to diamond, which starts oxidation at 700°C, CBN has a thermal tolerance up to 1,300°C , so CBN is superior for high temperature processing.

Design to Minimize Adhesion of Tin to the Case Adjust the plating thickness in the tin plating process. The optimum shape is set to prevent tin from adhering to the problematic case, and titanium material is used to suppress it. ・Using titanium metal for the die casing, it is avoided the tin stick on the die casing. ・Standard case dimension is φ 25 × 7 mm ■Features
