Abstract: A newly proposed wire cleaning apparatus used for removing slurry from a wire, which reciprocatively travels between a slicing chamber and a wiring chamber. The wire cleaning apparatus has a couple of multigrooved guide rollers 41, 42 rotatably provided at a cover 30. A slurry receiver 20 is detachably attached to the cover 30. A centrifugal force is generated during repeated reciprocative movement of the wire 5 between the multigrooved guide rollers 41 and 42. Slurry is shaken off from the wire 5 by the centrifugal force and gathered in the slurry receiver 20. Removal of the slurry is accelerated by spraying a cleaning liquid W at the same time. Introduction of the cleaning liquid W into the slicing chamber is inhibited by on-off control of the cleaning nozzles 41, 42 in response to a travelling direction of the wire 5.
