Description

Grinding disk

The present invention relates to a polishing disk, and more particularly, to a polishing disk comprising a disk holder which is detachably attached to a polishing machine such as a grinder and a polishing wheel which is provided in the disk holder and which provides a polishing function through an abrasive, The abrasive is manufactured to be electrodeposited through a plating or bonding method while having abrasive on the polishing surface of a shank having a synthetic resin material or a metallic material having the cushion and the peripheral surface of the abrasive surface, And to improve the productivity and the workability.

In general, polishing refers to smoothing the surface of a solid by rubbing it with the edges or surfaces of other solids. It is used to polish the surface with abrasives (most of which are very hard materials used to polish stones or metal) .

In using the abrasive, the abrasive paper or the like, which is made of an abrasive agent, is manually hand-held and polished. However, a polishing machine may be used to polish a large amount of articles in a short time or to obtain a high degree of planarity and smoothness.

There is a hand grinder that can be easily grasped by hand. The grinder includes a body having a built-in motor and capable of grasping a hand, and a grinding disk fixed to the end of the body, So that the polishing operation is performed by the abrasive.

Here, the conventional polishing disk as described above is disclosed in a public utility model 1998-059542.

Fig. 1 is a view showing a conventional polishing disk as disclosed in the aforementioned Utility Model Application Publication No. 1998-059542.

1, a conventional polishing disk is provided with a disk holder 20 on the other side of which a polishing pad 10 having an abrasive deposited thereon is fixed to an end of a hand grinder, through an arm / And the surface of the object to be polished is polished in accordance with the contact between the object to be polished and the polishing pad 10 of the polishing pad 10 during rotation of the disc holder 20 according to the operation of the grinder.

However, according to the above-described conventional polishing disk, the polishing pad 10 does not have a state of being bonded to the edge of the polishing surface of the disk holder 20, and when the surface of the subject to be polished has a bent state, There is a problem in that the polishing operation can not be performed normally and the polishing operation must be performed by using other polishing means because the abrasive formed on the polishing pad 10 is not brought into contact with the surface of the surface and the boundary portion.

In addition, since the polishing pad 10 is bonded to the disc holder 20 via the female / male Velcro 30, the adhesion state between the polishing pad 10 and the disc holder 20 is lowered due to the heat generated during the polishing operation, The polishing pad 10 is detached from the disc holder 20, and the stability and productivity of the work greatly deteriorate.

In addition, when the adhesive force by the Velcro is lowered as described above, since the entire polishing pad 10 and the disc holder 20 need to be replaced, the service life of the polishing pad 10 is shortened, .
