Natural Diamond Wire Drawing Die

1.Natural Diamond Dies Introduction:

Natural diamond is the hardest material among the world's known materials. It has extremely high hardness, good thermal conductivity and photothermal properties. It is widely used in tool manufacturing, optical products and conductors in the industrial field. Its physical properties are: density 3.515g/cm3; hardness: 1.25-10.76GPa.
The diamond of the diamond wire drawing die which is usually used in the natural diamond wire drawing die is a diamond of type la diamond. Such diamonds contain certain nitrogen impurities (on the order of 0.1%) and these nitrogen impurities aggregate into small aggregates. It also contains small pieces (associated with nitrogen impurities), and the exact structure of these pieces is currently unknown.

The natural diamond wire drawing die produced by Coolervie is made of high quality natural diamond materials and has been carefully selected and processed. High surface finish and good wear resistance are its main advantages. It is suitable for the drawing of various types of wire with high surface quality requirements. Due to some unobservable defects in the content of natural diamonds, the service life of natural diamond wire drawing dies is quite different, which is the only shortcoming of its long-term use.

4. Process:

---Blank inspection-All PCD, MONO/SSCD, ND, and TC dies produced by Coolervie are checked under Microscope by 100X material magnification, so that dies with any impurities, cracks and spots could be easily detected and rejected. If these cracks or spots exist, the abnormal internal-stress will cause die cracking during die manufacturing or wire drawing process.
---Outer casing production:Only high-quality casing can be a good carrier for high-quality dies. Coolervie uses excellent stainless-steel materials, and completes three sets of process: cutting casing, creating setting area, and creating blank area in the cutting process of fully automatic machine tools, ensuring the perfect concentricity without moving the die shell.
---Reinforcement-Diamond should be firmly protected by metal matrix, which is formed by the sintered metal powder, reinforcing diamond to endure wire impact without breaking and to extend wire die life. Coolervie's auto-sintering process is accomplished by the combination of an infrared sensor, auto-feeder and a high frequency sintering machine.
---Coning-An automatic turning machine completes front and back cones and two parallel flats.
Cylindrical grinding-In order to ensure the precise dimension and roundness of casing, every casing should be ground by centerless grinding machine to tightly control the tolerance within 5 microns.
---Laser die profile drilling-The precision and consistency of our dies profiling has been improved dramatically since we purchased a state-of-art laser die drilling unit. A double side profile drilling is achieved by this most up-to-date laser drilling machines.
---Shaping and polishing-Advanced automatic or semi-automatic ultrasonic die working machine ensure the accurate die profile and good surface finish.
---Hole size calibration-Wire lapping machine is used for controlling precise tolerance of die hole.
