Different materials of wire drawing dies
At present, the materials of wire drawing dies include alloy steel dies, hard alloy dies, natural diamond dies, polycrystalline diamond dies, CVD diamond dies and ceramic dies. In recent years, some new materials have been developed.
Comparison of advantages and disadvantages of various wire drawing die materials:
Main comparison - advantages - disadvantages - scope of application
1. Alloy steel wire drawing dies- easy to make - poor wear resistance, short life - basically eliminated
2. Natural diamond drawing dies- high hardness, good wear resistance - high brittleness, difficult to process - wire die with a diameter of less than 1.2mm
3. Carbide wire drawing dies- good polishing, low energy consumption - poor wear resistance, difficult processing - various diameter wire
4. Polycrystalline synthetic diamond(PCD) wire drawing dies - high hardness, good wear resistance - difficult processing, high cost - small wire, wire
5. CVD coating wire drawing dies- high finish, good temperature resistance - complex process, difficult processing - small wire
6. Ceramic wire drawing dies- good wear resistance, high temperature resistance, corrosion resistance - thermal shock, poor toughness, difficult processing - not widely used
How to choose suitable wire drawing dies?
Drawing dies of different materials have their relatively reasonable processing objects. The rationality of drawing processing mainly refers to the matching of the mechanical, physical and chemical properties of the wire drawing die and the wire to obtain the longest service life of the die.
In the drawing process of small wire , natural diamond, polycrystalline diamond and CVD coating die are commonly used wire drawing die materials. When drawing small-diameter wires, the CVD-coated diamond die overcomes the anisotropy of the natural diamond die, and at the same time has excellent strength and hardness, the highest drawing output, and the surface quality meets the requirements. The test proves that the service life of CVD coated diamond wire drawing die is equal to that of natural diamond die, and the product qualification rate is high.

No clogging, easy to trim, extend the trimming cycle and reduce processing costs. 5. The cutting edge quality of the grinding workpiece is consistent and the smoothness is high, which ensures stable quality when processing downstream products.
At present, the main diamond processing methods include mechanical polishing, thermochemical polishing, tribochemical polishing, laser polishing, ion beam polishing and chemical mechanical polishing.Due to the anisotropy of diamond, "hard" and "soft" polishing directions have completely different material removal rates.Experimental results show that atomic-level roughness values can be obtained in a shorter time by mechanical polishing in the crystallographic directions <100> and <110> or in another direction deviating from <110> at an angle not exceeding 20°.
