Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting device including a dust removing mouth,

The present invention relates to a cutting apparatus, and more particularly, to a cutting apparatus including a dust removing tool.

Fig. 1 is a perspective view of a cutting apparatus according to the prior art.

Referring to FIG. 1, a cutting apparatus A according to the prior art generally includes a rotary saw blade 300 and cutting target support members 4, 5. In the cutting apparatus of such a structure, a rotary saw blade 300 rotating at high speed presses a cutting object fixed to the support members 4, 5 to perform a cutting operation.

However, the cutting apparatus A according to the related art has a problem that the foreign material generated during the cutting process is scattered in all directions by the rotary saw blade 300 rotating at a high speed during cutting the object to be cut. Therefore, a general cutting apparatus has a protective cover (not shown) attached to the vicinity of the rotating saw blade 300 to solve the problem. However, the protective cover (not shown) only solves the problem of the foreign matter scattering in all directions, and does not solve the problem that the foreign matter floats in the air and deteriorates the working environment around the cutting apparatus.

Therefore, there is a need for a cutting apparatus having a structure capable of solving these problems.
