Abstract
The invention relates to a serrated cutting tip and a serrated cutting tool having the cutting attached thereto capable of working a work piece at a fixed workability. The cutting tip includes a bond layer, which has super abrasive particles contained therein and grooves formed on a face which is in contact with the work piece, and a blank layer for strongly supporting the bond layer, by which a working plane of the cutting tip contacting the work piece is uniformly maintained during working use and debris can be readily discharged. As a result, workability is improved and lifetime is prolonged.
Claims31
A cutting tip attached to an outer periphery of a shank, which has a predetermined rotation radius and a first thickness, and adapted to work a work piece, the cutting tip comprising:
- a bond layer having a first width in a direction of the first thickness, a first height in a direction same as that of the shank and a radius of curvature same as that of the shank, the bond layer including grooves which are alternatingly formed on a first plane of the bond layer which is in contact with the work piece and a second plane of the bond layer adjacent to the outer periphery of the shank;
- and
- a blank layer having a second width in a direction of the first thickness, a second height in a direction same as that of the shank and a radius of curvature same as that of the shank, the blank layer being tightly coupled with the bonding layer in a corresponding manner with the grooves formed on the second plane of the bond layer adjacent to the outer periphery of the shank to attach the bond layer to the outer periphery of the shank,
- wherein the bond layer contains super abrasive particles and metal powder, and the blank layer contains metal powder.
A serrated cutting tool comprising:
- a shank having a predetermined rotation radius and a first thickness;
- and
- a cutting tip attached to an outer periphery of the shank for working a work piece,
- wherein the cutting tip comprises:
- a bond layer having a first width in a direction of the first thickness, a first height in a direction same as that of the shank and a radius of curvature same as that of the shank, wherein the bond layer includes grooves which are alternatingly formed on a first plane of the bond layer which is in contact with the work piece and a second plane of the bond layer adjacent to the outer periphery of the shank;
- and
- a blank layer having a second width in a direction of the first thickness, a second height in a direction same as that of the shank and a radius of curvature same as that of the shank, the blank layer being tightly coupled with the bonding layer in a corresponding manner with the grooves formed on the second plane of the bond layer adjacent to the outer periphery of the shank to attach the bond layer to the outer periphery of the shank, and
- wherein the bond layer contains super abrasive particles and metal powder, and the blank layer contains metal powder.
