近些年来,国外许多高等学校和研究部门在机床噪声的研究方面给予了很大的注意,而且取得了显著效果。欧洲机床工业合作委员会提出的噪声测量标准中规定,通用机床的噪声不得大于 85 dB(A),但实际上,各企业的机床产品噪声基本上控制在 80 dB(A)左右。近来欧洲某些企业已开始提出机 In recent years, many foreign universities and research departments have paid great attention to the research of machine noise and have achieved remarkable results. The noise measurement standards proposed by the European Machine Tool Industry Cooperation Committee stipulate that the noise of general-purpose machine tools should not exceed 85 dB (A), but in fact, the noise of the machine tool products of enterprises is basically controlled at about 80 dB (A). Recently, some European companies have begun to put forward the machine
