Multi-wire cutting device for controlling wire tension by adjusting Roller's position

摘要

The present invention relates to a multi-wire cutting device to enable tension adjustment using a position adjustable roller. The multi-wire cutting device includes: a first block in which a plurality of first coupling holes are formed; A second block having a plurality of second coupling holes formed therein; At least one first main roller which is rotatably and detachably fastened to the first coupling hole; At least one second main roller which is rotatably and detachably fastened to the second coupling hole; A cutting wire wound around the first and second main rollers; And a driving motor for rotating the first main roller or the second main roller, wherein the cutting wire is transferred when the first main roller and the second main roller rotate by the driving motor. Cutting, but the separation distance of the first main roller and the second main roller is characterized in that it is variable.
