Description of the invention () Fine cutting remains in the meantime. In such a cutting method, the screening operation of the sheet C and the thin band-shaped unused object c 'is extremely difficult. In particular, today's electronic parts are small in size, and the aspect ratio of the sheet C is as small as 0.6 (fflffl) X 0.3 (ffiffl). In this case, the sheet C and the thin band-shaped object C 'are not used. Screening is extremely difficult. In addition, if the front and back of the small piece C is only 0.6 (BIB) X 0 · 3 Uffl), it is pressed by a cutting blade A M guillotine to cut to maintain processing accuracy. Then the blade angle needs to be very small K to control the deformation of the cutting surface of the workpiece W to the minimum. Therefore, the cutting blade angle of these cutting blades A is composed of 10 to 30 degrees side-view V-shaped double-edged surfaces 2a, 2a, and the blade portion 2 is formed. The thickness of the blade portion 1 is only about 0.4 to lfflia. However, in order to control the deformation of the cutting surface of the workpiece W to the minimum, so that the blade angle is extremely small, and the thickness of the blade (the thickness of the blade body portion 1) is not changed, the areas of the left and right edge surfaces 2a and 2a become larger. It becomes a large resistance during breaking, and a large cutting force is required during cutting. As a result, the blade portion 2 has a problem of buckling and deformation. In addition, the cross-sectional shape of the blade portion 2 is an elongated rectangular shape. When pressing, the workpiece is often broken at the right-angle corners of the left and right blade surfaces 2a, 2a and the end portion, and high-quality sheet C is often not obtained. A huge impact on yield. The present invention is a solution to the above problems, and an object thereof is to provide a cutting blade, which is easy to screen ceramic laminates and the like when cutting a workpiece.

Description of the invention () Sheets and unused objects produced during cutting. Another object is to provide a cutting blade having high buckling strength and a sharp blade edge at a desired blade angle. Still another object is to provide a cutting blade capable of cutting a high-quality sheet having a regular length on four sides. The technical device to achieve the above-mentioned purpose is a flat-blade cutting blade, which is a workpiece V from a ceramic laminate and the like, and cuts a rectangular sheet C at regular intervals in the vertical and horizontal rows. Among them, the blade portion 2 formed from the blade tip to the blade body portion 1 is connected to the sheet C on the same line as the cutting object, and each of the cl on the straight line and the non-opposed portion 2b, and the non-opposed range portion It is characterized in that the non-cutting recessed portion 3 is recessed from the tip of the blade to a height direction orthogonal to the length direction of the blade, and the cutting blade portion 2 'is formed at equal intervals in the length direction of the blade. In the frontal technical device, the workpiece W sucked and held on the indexing table is rotated 90 degrees before the process, after the rotation, the process is to move the cutting processing device to the aforementioned marks M and M and lower the cutting blade. As shown in FIG. 8, the cutting of the blade portion 2 ′ is performed at each cutting, and only the sheet C is cut out in a vertical and horizontal direction from the workpiece W as if cut out. In addition, the blade portion 2 is a concavely curved surface 2c ', 2c' that is bilaterally symmetrical with respect to the center line X, forming a blade portion 2c and a commercial blade body portion 1 of a predetermined height gradually thickened. The blade edge portion 2c and the blade body are gradually thickened.

Therefore, the respective blades formed by a pair of concave curved surfaces 2d ', 2d' on the left and right of the blade tip portion 2c, and the connected portion 2d Thickness is less than the maximum blade thickness of the lower section. Thin-walled portions are gradually increased after forming in the middle. It is also effective when the thickness of the segmented blade is small. According to the above-mentioned technical device, the blade has less contact with the workpiece W, which further reduces the cutting resistance, and can cut the workpiece W with a smaller cutting force. Moreover, each piece formed at equal intervals is left. It is more appropriate to cut and implement the blade portion 2 ', and form both ends thereof in a plan view V shape.
