fig1 and the table 28 can be moved back and forth by a drive source which is not shown also there is erected a support member 30 on the left end portion of the slicing feeding table 28 on the front surface of the support member 30 there is supported a feed slider 32 such that it is free to move in the longitudinal direction of the support member 30 that is in the vertical direction the feed slider 32 is threadedly engaged with a feed screw which is not shown mounted in the longitudinal direction of the support member 30 and therefore the feed slider 32 can be moved in the vertical direction by means of rotation of the feed screw in addition the feed slider 32 supports an ingot 34 to which a slice base 36 is fixed thanks to this the ingot 34 can be moved in the directions of the arrows a b that is in the slicing directions as well as in the vertical direction that is in the direction for adjustment of the slicing thickness of the ingot referring now to fig2 there is shown a section view to illustrate a rotary mechanism 18 which is used to rotate the inner periphery slicing blade 14 and the grind stone 16 as shown in fig2 a cylinder shaped rotor 38 is mounted to a base section 40 which forms a.
