1. a scribing wheel for brittle material, this scribing wheel for brittle material is made up of such as lower part:

  • total rotary shaftThe bottom of two frustums of a cone intersect and form the edge, periphery of circumference crest line, and along described circumference crest line in circumference sideThe multiple breach being upwards staggered to form and projection,Described circle that described projection remains after being formed breach by described circumferential ribs line, that there is length in a circumferential directionWeek, the part of crest line was constituted, and described projection rolls when being crimped on brittle substrate, with at described fragility materialLine and the vertical slight crack stretched from line, its feature is formed towards the thickness direction of described brittle substrate on material substrateIt is,Described breach is formed with the spacing of 20~

    50 μ

    m on the complete cycle of described circumference crest line, its degree of depth be 0.5~

    3.0 μ

    m, the length on its circumferencial direction is shorter than the length of the circumferencial direction of described projection, and described breach has to describedThe breach face cut inside the radial direction of the bottom of stitch marker, the tangent line on the end of described projection lacks with describedActinal surface is with the angle of intersection of 30~

    60 °
