ND Dies, Natural diamond dies,Fine wire dies
ND Dies, Natural diamond dies usually used as Fine wire dies
Diamond is known as the hardest material in the world, has the extremely high degree of hardness and the good thermal conductivity and the light thermal properties, widely applies in the industrial field in the tool manufacture, in optics product and the conductor profession.
- Precise die orientation
- Accurate die profile
- Highly polished finish from bell to back relief
- Accurately sized
- Straight & consistent reduction angle
- Maximum wear resistance
- Minimum die pull
- Excellent wire surface quality
- Hole diameters: 0.013 - 1.000mm
STAR WIRE DIE produces high performance natural diamond dies which are widely used to draw fine wires like magnet wire (normally less than 0.5 mm), tungsten wire and stainless steel wire (less than 0.1 mm).
|Reduction Angle: Normal for Soft Materials is 16°- 20° Hard Materials is 12°- 16°.
Bearing Length: Shown at % of Hole Diameter. Normal for Soft Materials is 20% - 40%. Hard Materials is 40% - 60%.
