DIAMOND INSIDE BLADE CUTTER

摘要

PROBLEM TO BE SOLVED: To lower cutting resistance, to lengthen dress interval and to decrease the number of dressing by providing a metal layer with high thermal conductivity at least on the surface layer of the top part of an abrasive grain layer of the surface layer of the abrasive grain layer. SOLUTION: A high tension stainless thin sheet is used as an alloy and a base metal 1 is placed between vinyl chloride discs 2 under a condition the interval is kept at about 0.3mm and it is immersed into a nickel plating liq. with a liq. compsn. with a plating hardness of about Hv250 and while electric plating is performed, diamond abrasive grains 3 are fixed to form an abrasive grain layer 4. The abrasive grain used in this case is a natural diamond with a mean particle diameter of about 30μm and the thickness of the plating of the abrasive grain layer is 85μm on one side. A inner peripheral blade whetstone with a blade edge structure is prepd. thereby. A metal layer 5 is formed on this with copper plating.
