ダイヤモンドワイヤーソーに高張力が働くことと考え
る。The above-mentioned conventional diamond wire saw has a diameter of 20 to 25 m / air in air.
Although the cutting is performed while traveling at a speed of s, when used underwater, the vehicle can only travel at a speed of 4 to 5 m / s (see Table 1). If the vehicle is to be run faster than this, the size of the driving machine must be increased, and the wire rope 5 is also broken by high tension. The reason for not being able to drive fast is that the resistance is high in water and therefore
It is considered that high tension works on the diamond wire saw.

In the initial state, the diamond abrasive grains 2 protrude only about 0.1 mm from the surface of the bond 3 only by sand blasting. Bad stick. That is,
Bead 4 slips.

い。Means for Solving the Problems In order to solve the above problems, the present invention is premised on use in water, and the invention according to claim 1 uses beads in which diamond abrasive grains are dispersed and fixed in a bond. The known diamond wire saw, wherein the wire rope is fixed at required intervals in the length direction of the wire rope and the outer periphery of the wire rope between the beads is coated with a fixing material made of resin or the like, wherein the outer periphery of the fixing material is The surface was made flat, and the outer peripheral surface and the outer peripheral surface of the beads had a lower step than the latter, and the step was 0.5 mm or less. The step must be formed without fail, and therefore does not include 0 mm, that is, the case where both outer peripheral surfaces of the fixing material and the beads are flush.

ビーズ外周面と面一にした構成としたのである。According to a second aspect of the present invention, in the above structure, the fixing material in contact with the front end of the wire rope in the running direction of the wire rope on the outer peripheral surface of each bead is raised to be flush with the outer peripheral surface of the bead. It is.

用につれて、ビーズ表面が摩耗し（ボンドが摩耗し）、
ビーズと固定材の両外周面が面一となれば、走行抵抗は
より軽減されて、走行速度は向上し得る（表１参照）。The diamond wire saw according to the present invention travels in the same manner as in the prior art and cuts a stone or the like. At this time, the step between the outer peripheral surfaces of the fixing material and the beads is generally about 1.25 mm in the past, but is 0.5 mm or less. Reduction can be achieved, and the traveling speed can be improved. With use, the bead surface wears (bond wears),
If the outer peripheral surfaces of the beads and the fixing material are flush with each other, the running resistance can be further reduced and the running speed can be improved (see Table 1).
【００１０】また、ビーズと固定材の両外周面に段差を
形成しているため、使用初期においてもその段差の存在
により、ビーズ端縁が石材等に確実に喰い付き、円滑な
切削を行い得る。Further, since a step is formed on both the outer peripheral surfaces of the bead and the fixing material, the edge of the bead is surely bitten by a stone or the like due to the presence of the step even in an early stage of use, so that smooth cutting can be performed. .

定材の両外周面が面一になっても切削性に支障はない。Here, the diamond abrasive grains of the beads used in this type of diamond wire saw have a particle size of:
Most of them have a particle diameter of 0.5 mm. For this reason, in a state where both outer peripheral surfaces of the bead and the fixing material are flush with each other, the diamond abrasive grains are further reduced due to abrasion of the bond, and the spontaneous action of the cutting of the outer peripheral surface of the bead is performed. The protruding state of the grains is stable in sharpness. For this reason, even if both outer peripheral surfaces of the bead and the fixing material are flush, there is no problem in the machinability.
【００１２】固定材のビーズ端縁側を盛り上げたもの
は、その固定材の存在によってビーズの喰い付きが抑制
され、初期の喰い付きがよすぎる場合には有効である。
また、ビーズ端面の異常摩耗もその固定材の盛り上がり
によって緩和される。The fixing material in which the edge of the bead is raised is effective when the biting of the beads is suppressed by the presence of the fixing material and the initial biting is too good.
Also, abnormal wear of the end face of the bead is reduced by the swelling of the fixing material.

The beads 4 are fitted at required intervals in the length direction of the wire rope 5, the fixing material 6 is covered in a sleeve shape between the beads 4, and the beads 4 (metal ring 1) and the wire rope
Press in between step 5. The beads 4 are obtained by placing a metal ring 1 in the center of a mold, filling a metal bond 3 and diamond abrasive grains 2 therearound, and sintering them. After sintering, sandblasting is performed so that the abrasive grains 2 protrude from the outer surface of the bond 3. Perform so-called stand-out.

されて、円滑な切削作用が続行される。In the initial state, when a cutting operation is performed, the edge of the bead 4 smoothly bites into a stone or the like due to the presence of the step t, thereby performing the cutting operation. As shown in FIG. 5b, when the bonding material 3 is worn and the outer peripheral surfaces of the fixing material 6 and the beads 4 (bond 3) are flush with each other, the abrasive grains 2 may fall off or a new abrasive may be used. The grain 2 makes a face, and the blade is spontaneously generated, and a smooth cutting operation is continued.
