In addition to forming  grinding wheel dressing proper use of appropriate dressing tools, but also not ignore the following dressing essentials:
 1) diamond dressing tool tip should center of rotation in the same plane, and by trimming the center of the wheel spindle.
 2) In order to reduce the consumption of diamond pen, available when tinkering SiC wheel dressing tool. This can improve the efficiency of wheel dressing.
   3) If the wheel type face is connected to two convex arcs, you should trim a large arc; if it is a convex and a concave arc connected, you should first trim concave arc; if it is convex arc with line connected, should be trimmed straight; concave arc if it is connected with a straight line, you should first trim concave arc.
   4) by grinding the workpiece is convex arcs, then the repair concave arc radius of the wheel should be bigger than the workpiece radius 0.01mm; such as by grinding the workpiece is concave arc, then the radius of the wheel repair convex arc , should be less than the radius r of a small piece 0.01mm.
