Abstract

The present invention relates to a grinding wheel in which a grinding portion is joined to the outside of a grinding wheel body, and more particularly, to a grinding wheel having a tapered inclined surface (30) formed between the outer side of the grinding wheel body (10) The tapered inclined surface 30 has a concavo-convex coupling part 35 formed on the tapered inclined surface 30 to provide high durability because of high bonding force against grinding resistance during grinding work.

Description

{GRINDING WHEEL}

The present invention relates to a grinding wheel in which a grinding portion is joined to the outside of a grinding wheel body, and more particularly, to a grinding wheel having a tapered inclined surface at a boundary between an outer side of a grinding wheel body and a grinding portion, The present invention relates to a grinding wheel having high durability due to high bonding strength to grinding resistance.

Generally, a grinding machine is a machine tool for grinding a metal workpiece by a cutting action by a high-speed rotation of the grinding wheel.

Such a grinding wheel has been disclosed in various structures and shapes. As shown in Figs. 1 and 2, a grinding portion 2 composed of diamond, CBN abrasive grains and a bond is bonded to the outside of the grinding wheel body 1 .

However, since the boundary between the grinding wheel body 1 and the grinding portion 2 of the grinding wheel is joined by a simple horizontal surface 3 structure, the grinding wheel body 1 and the grinding portion 2) are easily separated from each other.

That is, since the coupling force between the grinding wheel body 1 and the horizontal plane 3, which is the boundary between the grinding wheel body 1 and the grinding wheel 2, is weak, the boundary between the grinding wheel body 1 and the grinding wheel 2 is easily separated Therefore, there is a problem that the durability of use is poor and the commerciality thereof is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a grinding machine which comprises a grinding wheel body and a grinding wheel body joined to each other by a tapered inclined surface, The present invention has an object of providing an excellent durability because of its high bonding force against grinding resistance during grinding work.

According to the present invention, a grinding portion composed of a diamond, a CBN abrasive and a bond is joined to the outside of a grinding wheel body having a shaft hole formed at the center thereof;

The outer side of the grinding wheel body and the boundary between the grinding wheel body and the grinding portion are tapered to form a tapered inclined surface.

According to the present invention, the concave-convex coupling portion is formed by any one of a rectangular concavo-convex shape, a semicircular concavo-convex or triangular concavo-convex shape.

According to the present invention, a grinding portion is joined to an outer side of a grinding wheel body, wherein a boundary portion between the outer side of the grinding wheel body and a grinding portion is formed as a tapered inclined surface, and a concave- It is excellent in durability and thus has an effect of improving the quality of the product.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a front and side sectional view showing a conventional grinding wheel.
2 is a front view and a side sectional view of a grindstone to which the present invention is applied;
3 is an enlarged view of a portion "A"
Figs. 4 and 5 are side sectional views showing another embodiment of Fig. 3; Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 2 to 5, the grinding wheel 20 having excellent bonding strength according to the present invention is formed by bonding a grinding portion 20 composed of diamond, CBN abrasive grains and a bond to the outside of a grinding wheel body 10 having a shaft hole 12 formed at the center thereof Respectively.

Particularly, the outer side of the grinding wheel body 10 and the boundary portion between the grinding portion 20 and the tapered inclined surface 30 are formed as a tapered inclined surface 30. The tapered inclined surface 30 has a concave- So as to increase mutual bonding force.

At this time, the concavoconvex engaging portion 35 is formed by any one of a rectangular concavo-convex, semicircular concavo-convex or triangular concavo-convex.

Hereinafter, the operation and operation of the present invention will be described.

The present invention is characterized in that a grinding wheel body 10 inserted into a rotating shaft (not shown) of a grinding machine and a grinding wheel 20 composed of diamond, CBN abrasive grains and bonding are bonded to the outside of the grinding wheel body, A boundary portion between the wheel body 10 and the grinding portion 20 is formed into a tapered tapered inclined surface 30 and joined together.

In addition, the tapered inclined surface 30 is not formed in a simple planar structure, but a concave-convex coupling portion 35 of a concave-convex structure is formed to increase mutual coupling force.

That is, the protrusions / depressions 35 may be formed in any one of concavo-convex structure of a quadrangular concavo-convex shape, semicircular concavo-convex or triangular concavo-convex shape at the boundary between the grinding wheel body 10 and the grinding portion 20 .

The grinding wheel of the present invention grinds a metal workpiece by a cutting action by a high speed rotation. The grinding force applied to the grinding portion 20 is transmitted to a boundary portion between the grinding portion 20 and the grinding wheel body 10 The formed tapered inclined surface 30 is primarily supported so that the bonding force is superior to the conventional horizontal surface structure.

Particularly, since the tapered inclined surface 30 is coupled with the concave-convex coupling portion 35 like a quadrangular concavo-convex, semicircular concavo-convex or triangular concavo-convex, not a simple planar structure, The bending strength of the boundary portion between the body 10 and the grinding wheel body 10 is further increased so that the grinding resistance applied to the grinding portion 20 can be adjusted by the irregular coupling portion 35 formed at the boundary portion between the grinding portion 20 and the grinding wheel body 10, So that the bonding force is further enhanced.

Therefore, in the present invention, the grinding portion 20 is joined to the outside of the grinding wheel body 10, the boundary between the outside of the grinding wheel body and the grinding portion is formed as a tapered inclined surface 30, (35), and has a higher bonding force against grinding resistance than a conventional horizontal plane structure in grinding work, thereby providing excellent durability.
