1. hard brittle material tracing wheel;

  • This hard brittle material with tracing wheel by constituting like the lower section;

    the bottom of two frustums of a cone of total turning axle is intersected and is formed the outer peripheral edges portion of circumference crest line;

    And a plurality of breach and the projection that are staggered to form in a circumferential direction along said circumference crest line;

    This hard brittle material is 4~

    20mm with the external diameter of tracing wheelSaid projection forms part residual behind the breach, that have a said circumference crest line of length in a circumferential direction by said circumferential ribs line and constitutes;

    Said projection is being crimped on rolling under the state of brittle substrate;

    On said brittle substrate, to form the vertical slight crack that line and the thickness direction from line towards said brittle substrate stretch;

    It is characterized in thatSaid breach forms with the spacing of 1000~

    5000 μ

    m on the complete cycle of said circumference crest line, and the length of said breach on its circumferential direction is shorter than the length of the circumferential direction of said projection.
