Slicing machine for slicing a crystal ingot with a rotary blade having an inner peripheral cutting edge |
摘要 |
<p>A slicing method is disclosed in which a crystal ingot is sliced by a rotary blade (14) while the inner peripheral cutting edge of the blade (14) is kept in a highly rigid state. In particular, in a slicing machine which is adapted to slice out a crystal ingot (20) into thin pieces by use of an inner peripheral cutting edge 16 of a doughnut-shaped rotary blade (14), an axial force is previously applied to the rotary blade (14) prior to starting of the slicing to thereby displace the rotary blade 14 in the axial direction thereof and thus, while the rigidity of the inner peripheral cutting edge (16) is kept in a high state, the crystal ingot (20) is sliced so as to realize a highly accurate slicing operation. <IMAGE></p> |
