PURPOSE:To make a saw blade difficult to cause vibration, to make the diamond tip difficult to cause its wear, besides to make the saw blade capable to be made in a thin blade which is difficult to be bent by escaping from even the bending mottles of the cutting place of a stone and to improve the cutting efficiency and the yield of the stone. CONSTITUTION:A stone 45 is placed on a slide 41 reciprocating in the fore and aft direction, the stone 45 is cut in the necessary quantity each from the upper part with the rotating lower peripheral face of a saw blade 7 borne on a support block 3 rotatable with the axis 1 in the right and left direction as the center being abutted on the stone 45 under the maintaining state at the specified position, in that case the above cutting is executed with a pair of rollers 29 supported on the arm 24 with the center of the saw blade 7 as the fulcrum being under the thrust contact state to the both side faces of the stone cutting position vicinity of the saw blade 7. |
