Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting stones or the like with a diamond tip saw, and particularly, when cutting hard stones or the like, it is possible to cut the stones accurately without lowering the feed rate of the band. Regarding things.

[0002]

2. Description of the Related Art The cutting mechanism of a diamond tip saw is
As shown in FIG. 1, first, the driving rotary body 1 and the driven rotary body 3
Are arranged, and these driving rotary body 1 and driven rotary body 3 are arranged.
A band 5 made of a steel plate is wound between them. A plurality of diamond tips 7 are attached to one side of the band 5 by metal bonding at a predetermined pitch. Then, the band 5 is rotated in the direction indicated by the arrow a in FIG. 1, and the work (for example, stone material) 11 is cut in the direction indicated by the arrow b in FIG. (Or stone 11 and band 5
Push into. ) Thereby, the work 11 is cut.

Recently, it has become possible to cut a thin plate having a thickness of about 3 to 5 mm from a hard stone material or the like with the above-mentioned diamond tip saw. In this case, conventionally, the band is directly cut into the stone as shown in FIG.

[0004]

According to the above conventional structure, there are the following problems. First, it was difficult to accurately cut the thin plate. This is shown by the one-dot chain line in FIG. 7, even though the diamond tip saw is different from the circular saw in that the entire surface of the band is evenly contacted with the stone material and the surface of the stone material is also polished and flattened in advance. As described above, when a diamond tip is suddenly cut into a hard stone, the diamond tip tends to escape to the left and right, and the cutting line shifts. Therefore, conventionally, the feed speed of the band was lowered until a groove serving as a guide was formed at the cut position, and the feed speed was increased after a certain amount of the cut groove was formed to perform the cutting, but the work is troublesome. Moreover, there is a problem that it takes a long time.

The present invention has been made on the basis of such a point, and an object thereof is to accurately cut and cut a band when cutting it into a work such as a stone material without reducing the feeding speed of the band. Another object of the present invention is to provide a method of cutting stones and the like with a diamond tip saw that can be used.

[0006]

In order to achieve the above object, a method of cutting a stone material or the like by a diamond tip saw according to the present invention is to cut a diamond tip saw having a plurality of diamond tips attached to one side of a running band into a work. In a method of cutting a stone material or the like with a diamond tip saw that cuts by inserting, a guide layer made of a soft material is formed on the front side of the band cutting direction in the work, thereby guiding the band. .. Further, by including an abrasive such as sand in the guide layer, the setting function of the diamond tip can be maintained together with the guide.

[0007]

As described above, according to the cutting method of the present invention, the guide layer of a soft material is formed on the front side of the band cutting direction in a work such as a stone material, and when the band is cut into the work, the soft material is first used. Since it cuts into the guide layer, it can be cut accurately without reducing the feed rate of the band, and when cutting into a work such as stone material, the guide layer serves as a guide, so there is no escape to the left and right of the diamond tip accurately Can be cut and cut. Further, when the guide layer contains an abrasive such as sand, the diamond tip is automatically set up every time it is cut, so that clogging and cracking can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. First, as the cutting mechanism of the diamond tip saw, as shown in FIG. 1, the conventional cutting mechanism is applied as it is. That is, the drive rotating body 1 and the driven rotating body 3 are arranged, and the band 5 made of a steel plate is wound between the drive rotating body 1 and the driven rotating body 3. A plurality of diamond chips 7 are attached to one side of the band 5 at a predetermined pitch. Then, the band is indicated by an arrow a in the figure.
By rotating in the direction indicated by, the band 5 is cut into the work 11 in the direction indicated by arrow b in the figure. Thereby, the work 11 is cut. The work 11 such as a stone material used here is a rectangular parallelepiped block having a flat surface as shown in FIG. Perform the cutting work to slice into thin plates of thickness.

In the present invention, the guide layer 13 is formed on the front surface side of the band 5 in the work 11 in the cutting direction. The guide layer 13 may cover the entire surface of the work 11 as shown in the drawing, or may be partially formed only at a cutting position. The point is that the guide layer 13 may be formed at the cutting line. The guide layer 13 is made of foamed cellular concrete in which sand and cement are mixed and foamed. Then, this is formed to a predetermined thickness and adhered to the surface of the work 11 with an adhesive. The guide layer 13 is made of a soft material and has a thickness that allows the diamond tip to be easily cut and can guide the band after the cut, and is arbitrarily selected.

Next, the cutting method of the present invention will be described. When the traveling band 5 is cut into the work 11 on which the guide layer 13 is formed, as shown in FIG. 4, the diamond tip 7 attached to the band 5 first cuts into the guide layer 13.
At this time, since the guide layer 13 is made of a soft material, the guide layer 13 is cut at a normal band feeding speed and can be accurately cut into a predetermined size. Further, when the guide layer 13 contains an abrasive 15 such as sand, the diamond tips are sharpened by the sand, and new diamond abrasive grains are exposed.

Next, when the diamond tip reaches the work 11, as shown in FIG. 5, the band 5 and the diamond tip 7 have grooves formed in the guide layer 13 which serve as guides and do not cause escape to the left and right. , Cut to the correct position and cut exactly according to the cutting line. Further, since the diamond tip 7 is in a sharpened state, the work 11 can be cut in a good cutting condition.

According to this embodiment, the following effects can be obtained. First, since the guide layer 13 made of a soft material is formed on the front surface side of the work 5 such as a stone material in the cutting direction of the band 5, when the band 5 is cut into the work 11 having the guide layer 13, the guide layer 13 made of a soft material is first formed. Since it is cut into 13, the cut can be accurately made without reducing the feed rate of the band 5. When cutting into the work 11 such as a stone material, the guide layer 13 serves as a guide to prevent the diamond tip 7 from escaping to the left and right, and it is possible to cut and cut accurately. Therefore, a product with accurate dimensions can be obtained.

If the guide layer 13 contains an abrasive 15 such as sand, the diamond tip 7 is cut every time it is cut.
Since it is automatically sharpened, clogging can be suppressed, and it is possible to prevent deterioration of cutting quality and generation of cracks 17 as shown in FIG. 7.

The present invention is not limited to the above embodiment.
For example, the guide layer 13 may be formed of foamed concrete alone, or may be made of other materials such as ordinary concrete and resin material. Also, the method of attachment is not limited to adhesion and is arbitrary. Further, the work 11 may be a hard material other than a stone material, and the shape thereof is not limited to the rectangular parallelepiped shape and may be any shape. Further, the guide layer 13 may be formed at least on the front surface side of the work 11 in the band cutting direction, and may be formed on the entire surface of the work including the other surface of the work or the front surface side.

[0015]

As described above in detail, according to the method for cutting stones or the like by the diamond tip saw according to the present invention, since the guide layer is formed, it is possible to accurately cut without lowering the feed rate of the band, and to the work such as stones. When cutting, the guide layer serves as a guide, so there is no escape of the diamond tip to the left and right, and accurate cutting and cutting can be performed. Further, when the guide layer contains an abrasive such as sand, the diamond tip is automatically set up every time it is cut, so that clogging and cracking can be prevented.
