がある。Therefore, conventionally, as shown in FIGS. 6 to 8, slits 12 of any shape are formed at equal intervals in the strip plate 11, and cutouts 13 are formed between the slits 12. , when bonding a chip 14 made of a material harder than the material of the strip plate 11 and the material to be cut to the cutout portion 13, the thickness of the cutout portion 13 of the strip plate 11 is smaller than that of the strip plate 11. After inserting the chip 14 formed thicker, the chip 14
While heating it, pressurize it from both sides to crush it.
The peripheral edge of the chip 14 is the notch 13 of the strip plate 11.
This manufacturing method of a band for cutting a hard material or metal is characterized in that the band is integrally bound to cover the outer peripheral edge 15 of the band (see Japanese Patent Publication No. 62-38088).
There is.
