It will not break after a lifespan of 0 to 500,000 times. In addition, in the case of a metal cutter, it is necessary to oil the sliding parts to prevent seizure. Since it is necessary to supply oil, the environment in which it is used becomes dirty and the workpiece becomes dirty, which may lead to poor quality. Furthermore, in the case of metal cutters, since chemicals are used in the manufacturing process for chemical fibers, etc., rust and corrosion are likely to occur.

"Example" As shown in Fig. 1, a fixed cutter 1 and a movable cuff 2
Both are made of zirconia. Reference numeral 3 is the fulcrum, and 4 is the cutting edge. In this cutter, a warp ΔL is applied to the blade member in the longitudinal direction as shown in FIG. 2B. Concerning the warping direction, convex warping or concave warping can be considered, and the combination thereof affects the sharpness and life. As shown in Figures 3 and 4, a convex blade on the 4th side is displayed as a (+) warp, and a concave blade on the 4th side is displayed as a (-) warp, and the number of cuts per hour is 100. Fig. 5 shows the experimental results of the relationship between warpage and sharpness, using an example in which +11 is a fixed cutter, (2) is a movable cutter, the upper side of the table is a zirconia cutter, and the lower side is a metal cutter. show. Furthermore, the relationship between sharpness and service life is shown in FIG. From the results shown in Figures 5 and 6, the zirconia cutter is
It was confirmed that if a warp of 0.2 to -0.2 is applied, the life will be long.

"Effects of the Invention" As described above, the present invention provides a cutter consisting of two blade members, in which the blade members are made of zirconia ceramic, and the blade members are warped by +0.2 to -0.2 in the longitudinal direction. This is a cutter that has a conventional metal cutter.
For a lifespan of 400,000 to 1,500,000 times, the cutter of the present invention has a lifespan of 1
It has a long life of more than 0 million cycles. In addition, in the case of a metal cutter, it is necessary to lubricate the sliding parts to prevent seizure, but in the case of the zirconia cutter of the present invention, it is possible to do so without lubrication, and there is no need for lubrication, so the usage environment The workpiece is clean and the quality is improved. Furthermore, due to the manufacturing process of chemical fibers and the use of chemicals, rust and corrosion occur with metal cutters.
This does not occur with the cutter of the present invention.
