Impregnated Diamond Dressers

  
 
   

Impregnated Diamond Dressers contains large number of processed Blocky Diamond granules, uniformly distributed. They are manufactured according to the Grit Size, Concentration and application, where surface finish is the criterion. These types of dressers are applied in thread grinding with grit specification 'f', 'ff' and 'fff'.

The important factors affecting the performance of Diamond Dressers are:
 
  • Type of Natural Diamonds

  • Effect of Heat on Diamond

  • Abrasion Resistance & Orientation
 
     
 

Types of Natural Diamonds
Shape of Diamonds vary from Octahedron, Dodecahedron, Cube, Macle, Elongated and Twinned Diamonds. Quality of any diamond is mainly a matter of structure. If the structure is irregular with inclusions, weak spots, flaws, air pockets and carbon impurities, the diamond is liable to fracture or wear excessively. Most of the good quality diamonds are mined form South Africa. However there is no correlation between Quality, Origin and Color.

Effects of Heat on Diamond
At higher temperature Diamonds turns into graphite and oxidizes. Temperature at which Diamond is damaged depends on its quality. In dressing process, Diamond must be cooled.

Abrasion Resistance and Orientation
Resistance to abrasion of Diamond is related to its structure. It varies from one direction to another and from one plane to another. The "ART" of setting a Diamond in a position, so that most wear resistant line of attack is used is called as "Orientation".
