SUPER HARD ALLOY BASEPLATE OUTER CIRCUMFERENCE CUTTING BLADE AND MANUFACTURING METHOD THEREOF

摘要

The disclosed super hard alloy baseplate outer circumference cutting blade is formed from a super hard alloy and has a cutting blade part on the outer circumferential edge of a thin circular ring-shaped baseplate. The cutting blade part contains: 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 metal and/or alloy with a melting point no greater than 350°C impregnated between the abrasive grains and between the abrasive grains and the baseplate. Also disclosed is the manufacturing method of said super hard alloy baseplate outer circumference cutting blade.
