摘要： PROBLEM TO BE SOLVED: To prevent wire gathering/separation caused by the surface tension of cooling liquids adhered partially to many wires, in a multi-wire saw. SOLUTION: The multi-wire saw 1 cuts a workpiece 4 into many thin wafers 5 by bringing the traveling many wires 3 into contact with the workpiece 4 while supplying the cooling liquids 7 to the wires 3 with many fixed abrasive grains parallel at prescribed pitch. When cutting is started, the wires 3 are traveled at a low speed in a state that the cooling liquids 7 are not supplied and the wires 3 are bitten into the workpiece 4. After the cutting is formed at a cutting starting position of the workpiece 4, the supply of the cooling liquids 7 is started, wire speed is increased, and the cutting of the workpiece 4 is continued by making the wire speed as normal time speed.

摘要： PROBLEM TO BE SOLVED: To simplify a structure of a workpiece measuring device, and to easily execute workpiece measuring work for workpiece positioning in a short time.SOLUTION: A wire saw is constituted so that a plurality of annular grooves 15 are formed at outer circumferences of a plurality of working rollers 14 arranged on axes parallel to each other, and a wire 16 is turned between the annular grooves 15, and a workpiece W is cut by the wire 16 at a position between the working rollers 14. Wide annular grooves 26 for measurement which are parallel to the annular grooves 15 for wires and wider than the annular grooves 15 for wires are formed on the outer circumference of one end of each of the pair of working rollers 14 facing each other. A bar 28 of a workpiece measuring device 27 is stretched over between the annular grooves 26 for measurement, and the end face position of the workpiece W is measured by a measuring instrument 29 which is movably supported on the bar 28, and the crystalline azimuth of the workpiece W is measured thereby.

摘要： PROBLEM TO BE SOLVED: To prevent wire gathering/separation caused by the surface tension of a machining liquid adhered partially to many wires, in a multi-wire saw. SOLUTION: The multi-wire saw 1 cuts a workpiece 4 into many thin wafers by bringing the many traveling wires 3 into contact with the workpiece 4 while supplying the machining liquids 7 to the many parallel wires 3. In the multi-wire saw, a liquid holding plate 8 is arranged in a wire gathering/separation generation region at lower sides of the many wires 3 corresponding to the workpiece 4, and a gap for holding the liquids is formed between the many wires 3 and the liquid holding plate 8. When the cutting of the workpiece 4 is started by the travel of the many wires, the machining liquid 7 is filled on the liquid holding plate 8, all of the wires 3 are dipped into the machining liquid 7, the surface tension of the machining liquid 7 eliminates influences on the wires 3, and thereby wire gathering/separation is prevented.
