<p>The saw consists of a row of wires (2) which are tensioned between at least two wire guide cylinders (4) and perform a continuous or reciprocating motion while held against the workpiece (31) to be cut, which is mounted on a support (3). The wire guide cylinders have an outer covering which can be charged when it is worn or to modify the spacing between the wires. The covering is in segments fixed to the cylinders' outer surfaces, and is made from a metal coated with a synthetic material, preferably polyurethane, with grooves in it for the wires. The metal is one with a low coefficient of expansion, e.g. an Fe-Ni alloy.</p> |
