PURPOSE:To provide a wire supply method for a wire saw by which a wire supply speed can be maintained at a low speed even if a workload is increased and groove machining of a multiple groove roller can be carried out easily and a wire reel can be made lightweight and failure processing of a work can be restrained. CONSTITUTION:In a wire supply method by which two or more wires 1 and 2 are wound round respective V groove groups of plural number of multiple groove rollers 7 in a multiparallel shape, a wire supply speed can be lowered by reducing an abrasion loss of the wires 1 and 2. Thereby, in the case where the wires 1 and 2 are put in reciprocating differential motion, a workload balance of the wires 1 and 2 between an outward route and a backward route can be improved, so that processing accuracy can be also improved significantly. |
