Manual dressing of the grinding wheel is an important factor in producing satisfactory work on your crankshaft grinder. The wheel must be dressed each time it is placed on the machine, even though it may not have been removed from the wheel center.
Mount the wheel dresser on the grinder table. Bring the rotating grinding wheel up close to the diamond and start the coolant flow. Never dress without coolant. Frictional heat buildup can cause the diamond to come loose or separate from its mount. Lack of lubricating properties, along with cooling, abrades the diamond needlessly.
Best results will be obtained if the diamond is brought into contact with the center of the wheel; fed in a maximum of .002˝ then traversed each direction (left and right) off the edge of the wheel. Learning the best traverse rate for dressing the wheel is a matter of trial and error for each operator. You have to be fast enough to prevent glazing, but slow enough to minimize spiral lead marks.
Dressing from the center of the wheel outward to each edge helps minimize the effect of the spiral lead marks on the finish of the workpiece. Do not remove more than .002˝ per pass. Excessive in-feed will cause the wheel to act like it
