(1) "Shoulder grinding" means a periphery grinding operation where a limited amount of grinding with the side of the  wheel  may  be performed.

(2)     "Snagging" means the grinding which removes relatively large amounts of material without regard  to  close   tolerances  or  surface   finish requirements.

(3)    "Surface feet per minute" or "sfpm" means the distance in feet that any 1 abrasive grain travels in l minute on a  peripheral   surface  of  a rotating grinding wheel.

(4)   "Surface grinding" means the precision grinding of a  plane  or  formed surface.

(5)   "Tool or cutter grinding" means the precision grinding or sharpening of various types of cutting tools.

(6)   "Tuck pointing" means the removal, by grinding, of mortar, cement, or other nonmetallic material.

(7)    "Wheel types" means the classification of abrasive wheels as     listed in the following order:

SHAPE TYPES OF GRINDING WHEELS

SHAPE TYPES OF GRINDING WHEELS CONES AND PLUGS

On all cones and plugs grinding is performed by all surfaces except the flat (dimension “D”) on the mounting side. These shapes normally have a blind hole threaded bushing for mounting.

RELIEVED AND/OR RECESSED WHEELS

A relieved side is a depression in the side of the wheel which is tapered from a radial flat at the periphery

(A) to an inside flat (K) or recess diameter (P).
