WIRE TYPE CUTTING WORKING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent warpage or undulation to accurately perform cutting. SOLUTION: The wire 4 provided between grooved rollers 12a, 12b, 12c under tension is allowed to run alternately in reverse directions by operating the drive motor 12d of a wire running device 2. The running direction altering operation of the drive motor 1d is detected by the pressing force detector 23 provided to a pressing device 3 and the pressing moving speed of a member W to be cut to the wire 4 by the press device 3 is controlled by the detection signal of the pressing force detector 23 so that the pressing force of the member W to be cut to the wire 4 is kept constant.
