Steps To Maximize The Life Of Your Resin Bonded Grinding Wheels
To achieve the best performance from a resin bonded Diamond or CBN grinding wheel, it must first be trued and then dressed on the machine it is to be used on. Truing involves grinding or wearing away of the abrasive surface, so that it will run concentric with the axis of rotation. Depending upon the type of abrasive, the following truing methods will apply.

Once truing has been completed, the surface of the grinding wheel face will be smooth, with few abrasive crystals protruding. It is imperative for the Diamond or CBN wheel to be dressed so that new cutting points can be exposed. This is accomplished by holding an aluminum oxide stick( catalogue numbers 50012 & 50013 ) firmly against the rotating wheel face, allowing the stick to remove some of the bond material. When the stick begins to wear rapidly, proper dressing has been accomplished, and the superabrasive wheel is ready for use.
