Abstract

(57) [Summary] [Object] The present invention provides a stone polishing machine in which each polishing member is similarly worn and a good cooling effect is obtained. [Structure] A stone polishing machine according to the present invention is a stone polishing machine which mounts a plurality of polishing members on one surface of a main body 10 to rotate a stone around a central axis to polish a stone and supply cooling water through the attached shaft. As the polishing member, a plurality of tangential polishing members 15 arranged near the outer periphery and extending around the central axis, and a plurality of radial polishing members 16 inside the tangential polishing member and extending radially are provided. It is characterized by that.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stone polishing machine that is attached to a rotating shaft to polish stone.

[0002]

[Prior art]

 In the conventional stone polishing machine, a plurality of polishing members are attached to one surface of a disk-shaped main body and rotated around the central axis to polish the stone material and supply cooling water through the attached shaft. . However, since the speed of rotation of the polishing member is higher toward the outer side away from the central axis of the main body, the amount of wear becomes larger, and the inner polishing member had to be replaced with almost no wear. In order to solve such a point, a stone polishing machine is also used, which has a polishing member formed so as to extend in an arc shape around the central axis line and made longer toward the outer side, but cooling water hits the inner polishing member and the There was a drawback in that the polishing member and stone could not be cooled sufficiently and overheated and deteriorated.

[0003]

[Problems to be solved by the device]

 The present invention provides a stone polishing machine in which the polishing members inside and outside are worn out almost in the same manner, and the cooling water flows well to obtain a sufficient cooling effect.

[0004]

[Means for Solving the Problems]

 This invention is a stone polishing machine for mounting a plurality of polishing members on one surface of a main body to rotate a stone about a central axis and supplying cooling water through the attached shaft. Stone material characterized in that a plurality of tangential polishing members arranged in the tangential direction around the central axis and extending in a tangential direction and a plurality of radial polishing members inside the tangential polishing member and extending radially are provided. It provides a polishing machine.

Embodiments of the present invention will be described below with reference to the drawings. In the embodiment of the present invention shown in FIGS. 1 and 2, reference numeral 10 is a disk-shaped main body, for example, having a hole 13 penetrating its central portion. The hole 13 is shown to have a step, but it may have no step. Further, the main body 10 may have a planar shape other than the circular shape. Reference numeral 15 denotes a plurality of tangential direction polishing members, for example, six, which extend around the central axis away from the center of the hole 13 near the outer periphery of one surface of the main body 10, and are brazed or bonded so as to project from the main body. It is attached by. Numeral 16 is, for example, six radial polishing members which are inside the tangential direction polishing member and which extend radially with respect to the central axis. This radial polishing member is, for example, three outer radial polishing members arranged in the outer side at equal intervals extending inwardly from the vicinity of the tangential direction polishing member, and the outer radial polishing member alternately with the radius near the inner end thereof. There are, for example, three inner radial polishing members that are arranged at equal intervals and extend inward from the position to near the center. The area ratio of the respective polishing surfaces of the tangential direction polishing member 15, the outer radial polishing member 16 and the inner radial polishing member 16 is formed to be, for example, approximately 3: 2: 1.

When a stone is polished while supplying a cooling water by connecting a hollow shaft (not shown) to the hole 13 of the stone polishing machine, the cooling water is rotated by the radial polishing member 16 to be the impeller of the pump. Similarly, it is possible to accelerate and flow to the periphery to cool the polishing member and the stone material well, and at the same time, the tangential polishing member 15 and the radial polishing member 16 are worn at substantially the same amount.

In another embodiment of the present invention shown in FIG. 3, there is shown a case where nine tangential polishing members 15 and three radial polishing members 16 having exactly the same shape are provided. It was confirmed that even in such a case, the wear state was almost the same and a good cooling effect was obtained.

[0008]

[Effect of device]

 It is said that each of the polishing members 15 and 16 can be abraded in the same manner when polishing the stone material, and that the radial polishing member 16 satisfactorily flows without blocking the cooling water to sufficiently cool the polishing member and the stone material. Have an effect.
