Superabrasive electrodeposited cutting edge and method of manufacturing the same

A method of manufacturing a cutting edge, characterized in that a layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, to a first surface of a margin of a base member of thin-walled metallic material, adjacent to a border and extending therefrom, and then base member material forming the margin and opposite to the deposition of said superabrasive particles is entirely or partly removed.

A method of manufacturing a cutting edge, characterized in that a first layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, to a first surface of a margin of a base member of thin-walled metallic material, adjacent to a border and extending therefrom, then base member material forming the margin and opposite to the deposition of said first layer or layers of superabrasive particles is entirely or partly removed, and then another layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, opposite to and coextensive with the first layer or layers of superabrasive particles.

A cutting edge for use in cutting and drilling tools including circular saws and blades, band saws, gang saws, annular blades, and core drills, said edge comprising a mass of superabrasive particles electrodeposited on a thin-walled metallic base member along a border of said base member,

• wherein said mass forms one or more layers at the border of said base member and fixed thereto, each layer comprises at least five superabrasive particles in a row with extending direction of said base member from the border, said base member comprises at the border thereof a thinner-walled stay member, to which said superabrasive mass is fixed entirely or partly, and said stay member exhibits a zigzag contour along a perpendicular direction to the extending direction from the border of said base member.

A method of manufacturing a cutting edge, characterized in that a layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, to a first surface of an edge stay of a base member, the edge stay comprising a thin-walled metallic material adjacent to and extending from a border of the base member, and then the edge stay is entirely or partly removed.

A method of manufacturing a cutting edge, characterized in that a first layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, to a first surface of an edge stay of a base member, the edge stay comprising a thin-walled metallic material adjacent to and extending from a border of the base member, then the edge stay is entirely or partly removed, and then a second layer or layers of superabrasive particles are fixed, by an electrodeposited metal layer, continuously or intermittently, opposite to and coextensive with the first layer or layers of superabrasive particles.

A cutting edge for use in cutting and drilling tools including circular saws and blades, band saws, gang saws, annular blades, and core drills, said edge comprising a thin-walled metallic base member, an edge stay, and, a mass of superabrasive particles electrodeposited along a border and over the edge stay of said base member, wherein said mass forms one or more layers at said border of said base member and fixed thereto, and each layer contains parts comprising at least five superabrasive particles in a row in an extending direction of said base member from said border, and said superabrasive mass has a projection length twice or more as great as the thickness of the base member.
