摘　　要：为了降低金刚石锯片的切割噪声,制作5种规格锯片。并对其分别进行了6项改进,包括打孔、切窄缝(0.5 mm)、切窄缝注胶、切宽缝(1.5 mm)、切宽缝注胶以及改为双基体。分别对两种不同硬度的材料进行切割,在距离切割3 m处,用噪声计测量噪声。试验表明,6项改进大部分有降噪效果:打孔可降噪-2~4 dB,只切缝不注胶可降噪0.5~7 dB,切缝/注胶可降噪1~7.5 dB,改用双基体可降噪1.5~9 dB,即降噪效果:双基体>切缝/注胶切缝>打孔,其中Ф180和Ф230降噪效果明显,Ф115和Ф350略差。In order to reduce the cutting noise of diamond saw blade,five specification kinds of saw blades are made.Six improvement items have been made respectively,including to punch a variety of silencing holes,laser cutting many narrow seams of 0.5 mm,cutting narrow seams and rubber injection,laser cutting 1.5 mm wide seams,cutting wide seams and rubber injection,and changing to bimatrix.The noise is tested with a noise meter at a distance of 3 meters from the cutting saw blade.The test result shows that most of the six improvement items have noise reduction effect,punching holes can reduce noise by-2-4 dB,only cutting seams can reduce noise by 0.5-7 dB,noise-absorbing rubber injection into seams can reduce noise by 1-7.5 dB,and using bimatrix can reduce noise by 1.5-9 dB.Especially,the noise reduction effect is very obvious for two specification kinds of saw blades,Ф180 andФ230,and it is slightly worse forФ115 andФ350.
