することができる。 As described above, the present invention prevents the buildup of the abrasive grain layer by partially protruding and covering the groove, the end face of the base metal, or the cemented carbide abrasive fixing portion of any of these with an insulating plate having the required rigidity. Since the part and/or the hanging part can be eliminated, a cutting blade with low cutting resistance can be manufactured.
また、絶縁板は部分的にせり出すだけであり、
砥粒固着部分の全面を被覆するものではないの
で、メツキ液の流通が十分に確保され、生産能率
を阻害することがない。 In addition, the insulating plate only partially protrudes,
Since it does not cover the entire surface of the part where the abrasive grains are fixed, sufficient distribution of the plating solution is ensured and production efficiency is not hindered.
