Abstract

PURPOSE:To absorb the vibration between plates with different proper vibration frequencies each other so as to reduce a noise, by holding a steel plate on which numerous holes are formed on almost the whole surface, with other steel plates, and connecting and integrating those plates to form into a substrate for cutter. CONSTITUTION:This cutter has a round substrate 1, notches 2 in the radial direction are formed at the peripheral edge of the substrate 1, and diamond chips 4 are fixed to the outer edge of segments formed by the notches. The substrate 1 is composed by connecting three sheets of steel plates 1a to 1c each other by a spot welding, and in this case, a plate with the thickness 0.6mm, and nemerous holes 5 are formed along the whole surface, for example, is used as the middle plate 1a, while plates with thickness 1.2mm are used as the plates 1b and 1c provided on both outer sides. Consequently, the proper vibration frequencies of the plates 1a to 1c are made different each other, and the noise can be reduced by absorbing the vibrations of them.
