Abstract
In a multi-wire saw, each wire guide has a cylindrical exterior configuration, and is composed of sectorial portions which are circumferentially separated and integrally formed in the axial direction thereof. Each sectorial portion provided in the wire guide has wire guiding grooves extending circumferentially on the peripheral surface thereof in parallel along the axial direction of the wire guide, and one group of sectorial portions which are located alternately to another group, is projected further out than the other group of sectorial portions, to form an envelope of a cylindrical shape as an exterior form.
