Embodiment Construction
[0050] Although the scribing wheel of the present invention will be described in more detail below, the present invention is not limited to these embodiments.
[0051] figure 1 and figure 2 One embodiment of the scribing wheel of the present invention is shown. figure 1 is the front view seen from the direction of the axis of rotation of the marking wheel, figure 2 for side view. Such as figure 2 As shown, a blade 11 having a substantially V-shaped cross section is formed on the peripheral portion of the disk-shaped wheel.
[0052] The front edge angle θ of the blade 11 is usually an obtuse angle, and the specific angle is appropriately set according to the material or thickness of the substrate to be cut, but is usually in the range of 90 to 160 degrees (for example, 100 to 140 degrees). In addition, if figure 1 As shown, a plurality of V-shaped grooves 13 are formed at predetermined intervals on the ridge line of the blade 11 , that is, the blade leading edge 12 ...
