Abstract
A cutting process in which a blade under tension is moved relative to a workpiece. The blade has a longitudinally-extending abrasive-holding portion defined by blade material that is softer than the workpiece to be cut and overlies a high tensile strength core. The abrasive-holding portion defines a cutting surface extending between opposite sides of the blade and defining less than one-half the total outer surface of the blade, and abrasive particles are partially embedded into a longitudinally-extending segment of the cutting surface but not into the sides of the blade.
Claims14
A system for charging abrasive particles into a blade including a longitudinally-extending abrasive-holding portion as said blade is moved in a direction generally parallel to its length, said system comprising:
- a charging roll mounted for rotation about an axis generally perpendicular to the direction of movement of said blade and including an annular groove having a width slightly greater than the width of said abrasive-holding portion and less than the sum of said width of said abrasive holding portion plus twice the nominal size of said particles, whereby said blade may be charged by positioning said abrasive-holding portion in said groove and embedding said particles into the portion of said abrasive-holding portion facing the base of said groove.
A system for charging abrasive particles into a blade including a longitudinally-extending abrasive-holding portion as said blade is moved in a direction generally parallel to its length, the portion of said blade into which said particles are to be charged defining in traverse cross-section an arc, and said system comprising:
- a charging roll mounted for rotation about an axis generally perpendicular to the direction of movement of said blade and including an annular groove having an arcuate base subtending an arc of less than 180 degrees and extending the width of said groove, the radius of said arcuate base of said groove being greater than that of said arc of said portion and less than the sum of that of said arc of said portion and the nominal size of said particles, whereby said blade may be charged by positioning said abrasive-holding portion in said groove and embedding said particles into the portion of said abrasive-holding portion facing the base of said groove.
