         2 . A method of dressing the flat surface of the grinding wheel according to  claim 1 , wherein the dressing unit has a longitudinal axis, and wherein the step of rotating the dressing unit includes connecting a motor to the dressing unit to rotate the dressing unit about its longitudinal axis. 
     
     
         3 . A method of dressing the flat surface of the grinding wheel according to  claim 1 , wherein the dressing unit is barrel shaped. 
     
     
         4 . A method of dressing the flat surface of the grinding wheel according to  claim 3 , wherein the barrel shaped dressing unit has sides that are adapted to engage the flat surface of the grinding wheel. 
     
     
         5 . A method of dressing the flat surface of the grinding wheel according to  claim 4 , wherein the sides each have a first end and second end, and each end is chamfered. 
     
     
         6 . A method of dressing the flat surface of the grinding wheel according to  claim 4 , wherein the dressing unit sides are plated with a grit. 
     
     
         7 . A method of dressing the flat surface of the grinding wheel according to  claim 6 , wherein the grit is diamond. 
     
     
         8 . A method of dressing the flat surface of the grinding wheel according to  claim 6 , wherein the grit is cubic boron nitride. 
     
     
         9 . A dressing unit for dressing the flat surface of a grinding wheel, the dressing unit having a barrel shape, with sides that are adapted to engage the flat surface of the grinding wheel, with each side having a first end and second end, with each end being chamfered. 
     
     
         10 . A dressing unit for dressing the flat surface of a grinding wheel according to  claim 9 , wherein the dressing unit has sides plated with a grit. 
     
     
         11 . A dressing unit for dressing the flat surface of a grinding wheel according to  claim 10 , wherein the grit is diamond. 
     
     
         12 . A dressing unit for dressing the flat surface of a grinding wheel according to  claim 10 , wherein the grit is cubic boron nitride. 
     
     
         13 . A method of dressing a flat surface of a grinding wheel, the method comprising:
 the step of bringing a barrel shaped dressing unit into contact with the flat surface, the barrel shaped dressing unit having sides that are adapted to engage the flat surface of the grinding wheel, with each side having a first end and second end, with each end being chamfered, the dressing unit having a longitudinal axis, and   the step of rotating under power the dressing unit against the flat surface by connecting a motor to the dressing unit to rotate the dressing unit about its longitudinal axis.   
     
     
         14 . A method of dressing the flat surface of the grinding wheel according to  claim 13 , wherein the grit is diamond. 
     
     
         15 . A method of dressing the flat surface of the grinding wheel according to  claim 13 , wherein the grit is cubic boron nitride.
