Abstract
PURPOSE: To enhance the bond struength at the interface of a cutting edge layer of a diamond- base sintered material and a holding layer of special steel and improve toughness, machineability, etc. by forming the composite sintered part piece to be mounted to a cutting edge part into the two-layer composite body of said cutting edge layer and holding layer.
CONSTITUTION: A green compact piece of special steel or the like is inserted into a vessel, and the diamond-base powder to form its upper cutting edge layer is inserted and filled therein, thence these are sintered under an extra high pressure and temp., after which they are quickly cooled. This yields the composite sintered part piece comprising the two-layer composite body of a holding layer 1 imparted with hardness and a cutting edge layer 2 of a diamond-base sintered material. This is divided and cut and the cut piece is brazed to one corner of a cutting tip 3 made of superhard alloy or the like, whereby the two-layer construction of which the part to become a relief face and a rake face is constituted of the cutting edge layer 2 of the diamond-base sintered material is provided. Thereby, the composite sintered part piece for cutting edges having superior toughness and heat and abrasion resistances is obtained and the machining characteristics superior for machining of hard-to-machine materials are provided.
