9 GRINDING APPLICATION

but it is not a real circle, its a triangle-like or quadrangle like-circle. If workpiece is
put on the highter place than connecting line between centers of two griding wheels,
when bevel point on workpiece contacts regulating wheel , the point pressing against
grinding wheel doesn’t symmetrize it. Furthermore, skew poit contacts work rest.The
other parts on workpiece don’t touch the two griding wheels. In this way, diameter of
finshedworkpiece is longer than diameter got from above mentioned assumptive state;
only skew point is ground and coming out a nearly real circle through grinding. In
fact real circle is enhanced by supoort blade which is formed an angle on top of
workrest as point and line in fig. shown when lower part on surface of workpiece
contacts regulating wheel or blade cetner of circle on workpiece will descend. Its
ground diameter is shortere when center of circle ascends its ground diameter is
longer which resulting in a real circle because the uneven parts on workpiece offset
each other. Besides workpiece is easily upward severed because of higher angular
velocit or too high of center on workpiece.
