ることになり、反りの発生を防ぐことか垂壁となる。(Background technology) Many considerations have been made to prevent the occurrence of warping and warping during production of round-plated blades formed into a disk shape from a single copper plate. There is a problem. I got it, a general H-type copper circular saw blade has a Vickers hardness of 600 to 700.
In particular, when a round mackerel blade is made using zirconia Zr2O ceramics, the hysokurse hardness is 1.
000 to 1300, which means that the sharpness is greatly improved because it is extremely low. However, zirconia zr2
When manufacturing a round protection I-blade with a senmic phase such as O, the phase that warps during the firing process is thicker, making shield making more difficult than with general steel I. By the way, when the warpage becomes large, the cutting resistance becomes large and the cutting top 11t also becomes a shape, and it becomes a hanging wall in order to prevent the occurrence of warpage.

In addition, a positioning hole 1b, a heat dissipation hole 1, and a slit IC1 arc-shaped end face 1d for preventing sunburn are provided. Najaku, is the saw blade piece l zirconia zrto etc? It is made using the so-called 7'7-kutsuk method, which involves firing after molding. In general, the curvature of the saw blade is caused by heat treatment, or in the case of ceramic I/C metals, due to the micropatterns of the material being fired. CLtt's Tani Ayu force is somewhat warped, and even as a trap, the overall anti-ji firefly is extremely small.

Therefore, it is possible to reduce the cutting resistance by reducing the angle of 9, and it is also possible to cut hard materials more easily. 17t1 Since the heat dissipation P can be formed at the same time as the cutting of the saw blade, the slits for preventing sunburn can be formed at the same time, so there is also an advantage that the cutting edge can be improved.
