Quieter type Blade Saw

Quieter Type Blade Saw

The contact between the saw blade and the workpiece creates vibration during sawing which causes high noise generation. Quieter type blade saw, such as noise reducing diamond blade, with higher speed and smoother blade reduces the excitation of vibration and hence the propagation of sound.
