Dressing a wheel

[Highpower]

According to Machinery's Handbook:

Quote:Guidelines for Truing and Dressing with Single-Point Diamonds.—The diamond nib
should be canted at an angle of 10 to 15 degrees in the direction of the wheel rotation and
also, if possible, by the same amount in the direction of the cross feed traverse during the
truing (see diagram). The dragging effect resulting from this “angling,” combined with the
occasional rotation of the diamond nib in its holder, will prolong the diamond life by limiting
the extent of wear facets and will also tend to produce a pyramid shape of the diamond
tip. The diamond may also be set to contact the wheel at about 1?8 to 1?4 inch below its centerline.
