FIG. 6 is an explanatory view showing how the glass surface is polished by the cross section of the glass polishing machine 1. In order to polish a glass surface using the glass polishing machine 1 of the present invention, the paper 4 or the compression felt 5 is attached to the rotating disk 2b, the water is sprayed on the glass surface, and the glass polishing machine 1 is operated. And polish the glass surface. At that time, the operator moves the glass surface at a predetermined speed while holding the handle 2c with one hand and holding the hand above the rotary polishing tool 2 with the other hand in the P direction.

At that time, the turntable 2b rotates in a planetary manner along the outer circumference of the gear as described above (see FIG. 6 (a)). Further, although a force may be applied to the glass polishing machine 1 in the P ′ direction and the P ″ direction, by mounting the cover member 3 on the rotary polishing tool 2, a uniform force is applied to the glass surface. As a result, the inclination of the glass polishing machine 1 is prevented, and since water containing 2% of a neutral detergent is soaked, the glass surface can be polished smoothly.

Further, as shown in FIG. 6 (b), the rotary disc 2b has a rotation locus which is rotated to the outer peripheral shape of the gear for average polishing, and the rotary disc 2b has a conventional diameter. It is suitable for polishing curved surfaces because it is comparatively smaller than that of Further, the miracle of rotation of the turntable 2b is rotated to the outer peripheral shape of the gear, which prevents the outer peripheral edge of the turntable 2b from polishing only a specific position. As described above, in the glass polishing machine 1 of the present invention, by using the rotary polishing tool 2 with the covering member 3 mounted thereon, it is possible to prevent the polishing agent 6 from scattering during polishing of glass and to rotate during polishing. It is possible to prevent the polishing tool 1 from blurring and to move the glass surface smoothly because it has dampness.

Next, as the present embodiment, the manner in which the windshield of an automobile is polished using the glass polishing machine 1 having the above structure will be described. Generally, the windshield of an automobile is formed by a curved surface which is structurally gentle in fluid dynamics in order to reduce air resistance caused by traveling at high speed. In the case of polishing the windshield of such an automobile, the first paper 4A is attached to the rotary disk 2b of the glass polishing machine 1 for polishing, and then the first paper 4A is replaced with the second paper 4B. Grind.

After finishing the polishing with the second paper 4B, water containing about 2% of the detergent is sprayed from the spray container onto the windshield of the automobile. Next, a compression felt 5 is attached to the glass polishing machine 1, the cover member 3 is sprayed with water containing about 2% of a detergent from a spray container to be moistened, and the cerium compound 6 is added in an appropriate amount (for example, 5 g). Attach) Then, by moving the windshield about one reciprocation per place by the glass polishing machine 1 with the compression felt 5 attached, dirt and fine scratches can be repaired by polishing without excessively scraping the surface of the windshield, After polishing, the polishing agent may be removed by washing it away.

In the above embodiment, the windshield of an automobile is described as an example of the method for polishing the window glass. However, the method for polishing the window glass of the present invention is applicable to the window glass of a train or a building. However, the place and the kind of glass are not particularly limited as long as the glass requires polishing. Further, in the above-described embodiment, the cerium compound is used as the abrasive, but the material of the abrasive is not particularly limited as long as the same effect can be obtained.

[0028]

According to the window glass polishing machine of the present invention, since the covering member of the glass polishing machine is made to contain water for polishing, the polishing material is hard to dry and the rotary polishing tool can be easily moved. There are advantages. Since the glass polishing method uses air pressure to rotate the turntable,
Even if water is used in the polishing process, there is no fear of electric leakage or electric shock. Also, the turntable of the glass polishing machine is relatively small (1
(0 cm) and the rotation locus is configured to rotate like a planet along the outer circumference of the gear, so that the rotating plate comes into uniform contact with the glass surface and there is no variation in polishing, and the glass surface can be polished to a minimum. It is suitable for polishing curved surfaces.

Further, since the glass polishing machine does not use a motor, it has a small weight and is lower than conventional ones, so that it is stable and hard to shake when used, and can be used with one hand like an automobile windshield. It has the advantage that it can be used even with the hand extended. In addition, since the rotation of the turntable is relatively slow (750 rpm), it becomes easy to brake the moving direction of the glass polishing machine, and an operator unfamiliar with the polishing operation can easily perform the glass polishing operation.
