Basics

DRESSO impregnated tools contain tiny diamonds or crushed diamonds. The size of the diamond grain may be selected in relation to the size of the wheel grain of the grinding wheel to be dressed. The cross section of the diamond grain therefore does not exceed a desired size, whereby practically only diamond tips are used. DRESSO tools therefore provide the result of new, sharp grain diamond throughout their lifetime. The aggregate size depends on the dimensions of the grinding wheel.

Benefits:
≫ The work surface of the grinding wheel cuts freer and is more slip-proof.
≫ Reduction of grinding force.
≫ Extension of dressing intervals.
≫ High surface quality combined with high cutting ability of grinding wheel.
≫ High commercial value due to faster dressing traverse speeds and longer tool life (reduction of downtimes).
≫ Possibility of sharp-edged profiles on grinding wheels.

Basics:
≫ The dressing tool must absolutely be coordinated with the grinding process.
≫ Sufficient cooling is absolutely necessary. This preserves the diamonds and increases the tool life many times over.
≫ The dressing increment must be limited to a minimum (0.002 mm - 0.025 mm max).
≫ Never draw across the grinding wheel without infeed.
≫ An important factor is to determine the optimal overlap rate. This is a critical contributor to the grinding results. The overlap rate results
    from the product of the effective width of the dressing tool and the rotation speed of the grinding wheel over the dressing traverse 
    speed in mm/min.

Degree of overlap:
2  -  3  =  rough grinding                                          ud  -  degree of overlap
3  -  4  =  universal grinding bd  -  effective-width of dressing tool [mm]
4  -  6  =  finishing ns  -  revolution of grinding wheel [min-1]
 >  6  =  superfinishing vd  -  lateral dressing feed [mm/min]

vd  =  bd . ns / ud
ud  =  bd . ns / vd
udmax  =  grit size of grinding wheel [usmesh] / 15

NOTE! If bd > 3 mm for a multi-grain aggregate, then 35% of the effective width should be considered (d.h bd = d/3), since the grain portion is less than the effective width.
