摘要： PROBLEM TO BE SOLVED: To provide a cutter capable of high-speed cutting by thinning a cutting blade by strengthening a bond for forming a tip and reducing cutting resistance in a cutter containing abrasive grains such as diamond. SOLUTION: In the cutter, the high-speed cutting can be achieved by uniformly increasing a forming density of a portion joining the bond and a substrate, a plate part extending in the radial direction is interposed in the inner part of an abrasive grain layer, and through-holes are formed for joining the bonds facing each other with the plate part therebetween. The wall part forming the through-holes is incliningly provided with respect to the vertical direction to the radial direction of the substrate. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rotatable cutter having a joining strength to a substrate and increasing a cutting performance by providing a thin chip with a uniform forming density and an abrasive grain distribution. SOLUTION: A rotatable cutter has: a base plate 2 in which mounting holes are formed; a joining layer 7 formed radially outward of the substrate 2; and an abrasive grain layer 5 formed radially outward of the joining layer 7. The cutter further has a reinforcement member so extending as to ride over the joining layer 6 and the abrasive grain layer 5 in the radial direction of the substrate and joining these layers to each other. The reinforcement member is made of a metal sheet 9 or a metal mesh. When the reinforcement member is formed of the metal sheet 9, a large number of through-holes are so arranged that, when any circumferential line is drawn coaxially with the substrate, the through-holes appear. The chip having the joining layer and the abrasive grain layer, the substrate, and the metal sheet are firmly joined to one another without influencing the distribution of the abrasive grains of a diamond in the abrasive grain layer.

摘要： PROBLEM TO BE SOLVED: To provide a blade for cutting, which can suppress growth of wear due to deterioration in hardness at cutting edges and can maintain its cutting performance for a long time by radiating frictional heat generated during cutting.
SOLUTION: Frictional heat generated during cutting is radiated through a wavy cross-sectional portion 1 of the blade for cutting to suppress a temperature rise at cutting edges. As a result, deterioration in hardness is prevented and growth of wear is suppressed. Therefore, an initial shape of the blade is maintained for a long time and deterioration of its cutting performance is suppressed.
