PROBLEM TO BE SOLVED: To provide a cutting blade capable of precisely finishing the dimension of a workpiece by only a cutting operation and capable of eliminating a post-processing step after cutting.SOLUTION: The super hard alloy baseplate outer circumference cutting blade includes a cutting blade part 20 on the outer circumferential edge of a thin circular ring-shaped baseplate 10 formed of a cemented carbide. The cutting blade part includes: cBN abrasive grains and/or diamond abrasive grains formed by pre-coating with a magnetic material; a metal or alloy formed by electroplating or electroless plating which connects between the abrasive grains and between the abrasive grains and the baseplate; and a thermoplastic resin with a melting point of ≤350°C impregnated between the abrasive grains and between the abrasive grains and the baseplate, or a thermosetting resin formed by curing a liquid-state thermosetting resin composition with a curing temperature of ≤350°C impregnated between the abrasive grains and between the abrasive grains and the baseplate. |
