WIRE SAW AND WORK SLICING METHOD

IN A WIRE SAW, IT IS AN OBJECT TO SUPPRESS THE CUTTING THICKNESS OF A WORK, CUTTING CAPABILITY AND COARSE DEGREE OF A CUTTING PLANE FROM BEING VARYING BETWEEN THE ONE END AND THE OTHER END OF A MACHINING ROLLER. A PLURALITY OF MACHINING ROLLERS (13,14) ARE ARRANGED IN PARALLEL AT PRESCRIBED INTERVALS, AND A LARGE NUMBER OF CIRCULAR GROOVES (13A,14A) ARE FORMED ON THE OUTER PERIPHERY OF EACH OF THE ROLLERS. IN AN AXIAL DIRECTION OF THE MACHINING ROLLERS (13,14), A PLURALITY OF FLOWS OF SUPPLY REELS (23), TAKE-UP REELS (24) AND WIRES (15A,15B) ARE ARRANGED. THE WIRES (15A,15B) SUPPLIED FROM THE SUPPLY REELS (23) ARE WOUND ON THE CIRCULAR GROOVES (13A,14A) OF THE PLURALITY OF MACHINING ROLLERS (13,14) SO THAT THEY ARE TRAVELLED BETWEEN THE PLURALITY OF ROLLERS (13,14), AND TAKEN UP BY THE TAKE-UP REELS (24). THE WORK (20) IS CUT/SLICED BY A LAPPING OPERATION OF ABRASIVE GRAINS CONTAINED IN THE SLURRY WHICH ARE SUPPLIED ON THE RESPECTIVE SETS OF WIRES (15A,15B) WHICH TRAVEL BETWEEN THE PLURALITY OF MACHINING ROLLERS (13,14) IN A LONGITUDINAL DIRECTION IN A MANNER OF SHARING PREDETERMINED AMOUNTS.
