The present invention relates to a cutting wheel with blanks which reduces vibration and frictional noise generated when a workpiece such as stone, steel concrete, asphalt, metal, ceramic, or wood is cut, and a method for manufacturing the same. There is provided a cutting wheel of which a wheel body is formed with at least one blank. The blank is shaped in a line with a variable width, and the blank is filled with noise absorbing material. According to the present invention, the noise and vibration is considerably decreased as compared with a general plane type cutting wheel and a conventional cutting wheel with blanks. In addition, the cutting wheel with blanks according to the present invention can absorb the noise and vibration as good as the sandwich type cutting wheel, and particularly, is considerably high in strength, and is inexpensive to manufacture with ½ to ⅓ costs compared with the sandwich type cutting wheel.
A cutting wheel of which a wheel body is formed with at least one blank, wherein the blank is shaped in a line with a variable width, and the blank is filled with noise absorbing material.
