SUPER-ABRASIVE GRINDING DEVICE AND A MANUFACTURING METHOD THEREOF WHICH INCREASES CUTTING CAPABILITY BY ATTACHING A SUPER-ABRASIVE GRINDING PARTICLE LAYER TO AN EXTERNAL SIDE OF A WIRE ROD HAVING TENSION STRENGTH WHICH IS MORE THAN 35Kg/mm2

摘要

PURPOSE: A super-abrasive grinding device and a manufacturing method thereof are provided to attach a super-abrasive grinding particle by metallic bond by a brazing reactive metal.;CONSTITUTION: A cutting tool of ultra grinding property includes a wire rod(100) and an abrasive material layer(200). The wire rod material has a regular length. The wire rod has tension strength which is more than 35kg/mm2. The abrasive layer is formed in the circumference of the wire rod at a constant thickness. The abrasive material layer includes abrasive material particles(220). The abrasive material layer has Knoop hardness which is more than 2150 kg/mm2.;COPYRIGHT KIPO 2013
