For cutting the multi-thread machine and line compressing apparatus of stone

The present invention relates to a kind of for cutting the multi-thread machine of natural or cast stone, comprising: diamond wire loop；In a pair of of line guide roll of cutting section upstream and downstream；Compressing apparatus with movable support member, compressing apparatus are subdivided into the first tension device for moving greatly and the second tension device for subtle tension；First and second tension devices are vibrated around the first and second oscillation pins；Second tension device is subdivided into first and second groups in an alternating fashion, in a group for the adjacent diamond wire of even number and be the adjacent diamond wire of odd number in another group；Second subtle tension device space-alternating in one group in first and second groups, and in the space between the second adjacent tension device for being present in another group and between another group of adjacent diamond wire, each hypothesis in the second tension device is in each tightened position tensed, those of in first and second groups diamond wire from each other across.
