Abstract

PURPOSE:To prevent the surface of native stone from yellowing due to the rusting of iron powder by a method wherein a cutting device, which contains at least a cut-off abrasive wheel and a cutting water feeding means for circulatingly supplying cutting water to the cut-off abrasive wheel, is employed. CONSTITUTION:Cutting water 7, some part of which runs on the surface of native stone 4 and falls through the clearance at the side of a stationary stand 2 in a case 1, falls in the case 1 through the notched hole 2a of the stationary stand 2. The cutting water collected in the case 1 is pumped up with the pump 6b of a cutting water feeding means 6 so as to be fed to a nozzle 6a again for circulating reuse. Since the disc portion 5a of a cut-off abrasive wheel 5 is made of rustless material, even when powder-like matter, which develops through wearing at the cutting of the native stone 4, is by the cutting water and adhered to the surface of the native stone 4, no rusting of the powder-like matter develops through secular change. Even when the native stone cut at building site is pasted to wall or the like, no later yellowing due to rusting develops on the surface of the native stone.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone material processing method.

[0002]

2. Description of the Related Art A portable type cutting device for cutting natural stone material is provided, for example, with a fixed base 2 mounted on a case 1 and a movable base 3 reciprocated on the fixed base 2 as shown in FIG. The movable stone 3 is placed on the movable base 3 and the plate-shaped natural stone material 4 which is a workpiece is placed on the movable base 3 and is moved together with the cutting stone 5 placed on the fixed base 2. It is designed to cut 4. At this time, the cutting water 7 is supplied from the nozzle 6a of the cutting water supply means 6, and the cutting water 7 is positioned below the cutting grindstone 5 and drops into the case 1 through the notch hole 2a provided in the fixed base 2. Stored and fixed base 2
The cutting water 7 in the case 1 is sucked up by the pump 6b installed on the above through the hose 6c, and is supplied again from the nozzle 6a to the cutting position by the cutting grindstone 5.

[0003]

In this way, when the natural stones are attached to a wall or the like while being cut by the cutting device at the construction site as described above, yellowing is applied to the surface of the natural stones with the passage of time after the attachment. There were cases where discolored parts appeared. When the cause was investigated, the disk portion 5a of the cutting grindstone 5 was made of iron, and the iron powder was removed by the cutting water 7 due to wear during cutting.
It was found that the iron powder may be mixed in, and a part of it may be attached to the surface of the natural stone material 4 as it is, and may be rusted and yellowed due to aging. Then, this invention makes it a subject to provide the stone processing method which was able to prevent the yellow discoloration of the natural stone surface by such rust of iron powder.

[0004]

As a means for technically solving this problem, the present invention provides a cutting grindstone having a disk portion formed of a material that does not rust, such as stainless steel, and cutting water to the cutting grindstone. The gist is to cut and process a natural stone material by using a cutting device including at least cutting water supply means that is circulated and supplied. Furthermore, the gist is that the cutting device is a portable type.

[0005]

[Operation] Since the disk part of the cutting wheel is made of stainless steel or other non-rusting material, even if powdery substances are generated during cutting of stone and adhere to the surface of natural stone by cutting water, The powder does not rust.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings (the same members as in the prior art are designated by the same reference numerals). Figure 1
In the figure, reference numeral 1 denotes a case, on which a fixed base 2 is removably attached, and a notch hole 2a and a pair of guide grooves 2b are formed at important points.

Reference numeral 3 denotes a moving table formed in an almost L shape,
The guide piece 3a is attached to the lower part, and the guide piece 3a
Is slidably engaged with the guide groove 2b of the fixed base 2, whereby the movable base 3 is formed so as to be capable of reciprocating on the fixed base 2 along the guide groove 2b.

Reference numeral 4 denotes a plate-shaped natural stone material which is a workpiece, is placed on the moving table 3, and is cut by the cutting grindstone 5 while moving the moving table 3.

The cutting grindstone 5 is disposed above the notch hole 2a of the fixed base 2, and the disk portion 5a thereof is made of a rust-proof material such as stainless steel. The motor 8 shown in FIG. Is rotated.

Reference numeral 6a denotes a cutting water supply nozzle, which sprays cutting water 7 to the cutting portion when the natural stone material 4 is cut by the cutting grindstone 5.

The cutting water 7 thus sprayed falls into the case 1 from the notch hole 2a of the fixed base 2 as shown in FIG. 1, and a part of it flows on the surface of the natural stone material 4 to the side of the fixed base. It falls into the case 1 through the gap between the parts. The cutting water stored in the case 1 is supplied to the pump 6b of the cutting water supply means 6 as described above.
It is sucked up by and is supplied again to the nozzle 6a for circulation and reuse.

By the way, as mentioned above, since the disk portion 5a of the cutting grindstone 5 is formed of a material that does not rust such as stainless steel, the natural stone material 4 is abraded when cutting and a powdery substance is generated and flowed by the cutting water 7. Even if it is adhered to the surface of the natural stone material 4, the powdery material will not rust due to a change with time. Therefore, even if it is attached to a wall or the like after being cut at the construction site, the surface of the natural stone material 4 will not turn yellow due to rusting thereafter.

[0013]

As described above, according to the present invention,
In the method of cutting natural stone materials using a cutting water circulation type cutting device equipped with a cutting grindstone, the disk part of the cutting grindstone was made of rust-free material such as stainless steel, so it was rubbed at the time of cutting and powdered from the disk part Even if the powdery substance adheres to the surface of the natural stone due to the flow of the sprayed cutting water, it does not rust due to aging.Therefore, the yellowing of the surface does not occur after the natural stone is attached. Has the effect of preventing.
