DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method of manufacturing a stone working grinding machine.

[0002]

2. Description of the Related Art In the industry, marble, granite, and the like that have been generally cut and polished flat are called stone materials. Stone is repeatedly modified and polished to form beautiful and practical products. The most important step is the polishing of the corners of the stone, and the stone processing is a necessary and important manufacturing step for commercializing the stone.

[0003] The types and specifications of conventional stone processing and grinding machines vary widely. For example, the shape of the cross section of the stone processing grinding machine includes an arc shape, a ladder shape, a slope shape, and the like, and is used according to the processing shape. The standard is divided into rough polishing, fine polishing or fine polishing depending on the coarseness of the abrasive particles. A generally used grindstone processing and grinding machine is manufactured using an electroforming method or the like, using a hard member such as diamond or boulder powder as an abrasive. With the stone working grinding machine manufactured in this way, for example, rough grinding molding of stone as described in “Granite and marble construction method” disclosed in US Pat. No. 5,476,410 is performed.

As shown in FIG. 1, in a conventional stone processing and grinding machine, a grinding machine base 10 is manufactured in consideration of the processing shape of the stone. The grinder base 10 is provided with an abrasive on the outer surface, and a circular hole 25 is formed at the center of the axis 20 of the grinder base 10. The grinding machine base 10 is connected to the grinding device by the circular hole 25. As shown in FIG. 2, in the conventional stone processing grinding machine, an abrasive tape 30 provided with an abrasive 40 is adhered to the surface of the grinding machine base 10. This stone processing grinding machine is mounted on a grinding device, and the stone is processed by a rotary polishing method. At this time, the abrasive 40 provided on the abrasive tape 30 polishes the stone.

The surface of the grinding machine base 10 is provided with an arc and a curved surface as required. However, in the step of adhering the abrasive tape 30 to the grinder base 10,
Since the abrasive 40 is provided on the abrasive tape 30 in advance, it is difficult to completely and tightly adhere the abrasive tape 30 to the surface of the grinding machine base 10. For this reason, a deviation occurs in the grinding angle, which affects the appearance and angle of the stone material after molding. Further, a shearing force is generated between the abrasive 40 and the stone to be polished, and the abrasive tape 30 or the abrasive 40 falls off, affecting the stone processing.

As shown in FIGS. 3 and 4, in another conventional stone processing and grinding machine, an abrasive tape 30 provided with an abrasive 40 in the same manner as described above adheres to a different type of grinding machine base 10. Have been. This stone processing grinding machine
(1) adhesive force of the abrasive 40 to the abrasive tape 30;
(2) the adhesive strength of the abrasive tape 30 to the grinder base 10 and (3) the abrasive tape 30 to the grinder base 10
Is an important factor in manufacturing a stone working grinding machine, and is not a preferable manufacturing method.

[0007]

A conventional stone working grinder is manufactured by manually applying an abrasive to an abrasive tape, and then manually applying the abrasive tape to a grinder base. Applying the abrasive by hand is labor and time consuming. That is, production efficiency is limited and costs are increased. For this reason, the conventional stone processing grinding machine is expensive.
Also, when the abrasive tape is adhered by hand, wrinkles are liable to be generated on the tape, and the wrinkles cause errors in the polishing angle and the like, and the appearance of the stone processing grinding machine is not beautiful. Conventionally, stone processing is often performed by mechanical processing, and a stone processing grinder is mounted on a grinding device to perform polishing. However, when performing polishing, the abrasive tape is peeled off due to poor adhesion or the like. And other problems.

Accordingly, the present invention has been made to solve the above-mentioned problem, and has as its object to provide a method of manufacturing a stone working grinding machine which simplifies a manufacturing process and can be manufactured more easily. It is another object of the present invention to provide a method of manufacturing a stone working grinder in which an abrasive is tightly coupled to a stone working grinder and prevents the abrasive tape from coming off.

Another object of the present invention is to provide a method for manufacturing a stone working grinding machine which can save the manufacturing time of the stone working grinding machine and reduce the manufacturing cost. Another object of the present invention is to
It is an object of the present invention to provide a method of manufacturing a stone working grinding machine having a beautiful appearance and a precise polishing angle.

[0010]

According to the method for manufacturing a stone working grinding machine of the present invention for achieving the above object, an abrasive, a binder and a fibrous member are charged into a molding die,
Abrasive, binder and fibrous member are formed into an abrasive-containing member by a chill casting method or a hot press method, the abrasive-containing member is formed into a predetermined shape, and the abrasive-containing member is strengthened to strengthen the abrasive-containing member. One surface of the member is covered with an elastic member, and the abrasive-containing member covered with the elastic member is formed into a cover mat having a hollow portion, and the grinder base is covered with the cover mat. Glue. The cover mat can also be manufactured by filling an elastic member on one surface of a fibrous member and hot-pressing an abrasive and a binder.

The hollow portion of the abrasive-containing member may be directly filled with an elastic or hard member to form an integrally formed stone working grinding machine. Alternatively, it is also possible to form a stone working grinding machine in which the hollow portion of the cover mat is filled with an elastic member or a hard member and integrally formed. The abrasive-containing member has flexibility and is easy to remove from the molding die. Since the abrasive, the binder, and the fibrous member are formed at the same time, the abrasive is less likely to fall off during grinding.
