Impregnated Diamond Dressers is quite similar to that of Multipoint diamond dresser. In this dresser the crushed diamond grit in both Natural & Synthetic grades are set in a several layers in random pattern. With this type of tool, the dressing work is carried out by several small diamonds which together result in excellent performance. To achieve good results, the diamond particles must have at least double the grinding wheel grain to be dressed. Tools with higher diamond content are more efficient in this case. These tools are more suitable for fine and sensitive grinding wheels where a lower surface finish is required.


Advantages of Impregnated Diamond Dressers

  • Dressing time is reduced as higher feed rates can be used.
  • They are tougher & more wear resistance.
  • These tools can be used completely without any requirement of maintenance.
  • Extend wheel life by less stock removal per dressing.
  • No resetting or re - lapping required.
  • These tools are inexpensive and easy to use.


To get the maximum tool life

  • Set the multipoint tool into the center of the grinding wheel so that tool face gets completely in contact with the wheel.

  • Depth of cut should not exceed more than 0.02 - 0.04 mm.
  • Use plenty of coolant to increase the tool life.
  • The mounting must be vibration free, with the clamping length as short as possible.
  • Multi - point dressers must be used with higher crossfeed velocity rates than single point or blade dressing tools as their effective width is generally much greater.
  • Slower crossfeed rates would lead to high overlap ratios and thus may blunt the grinding wheel.
