噪声是机床产品的一个重要质量指标,它直接影响着操作工人的身体健康和机床产品在国际市场上的竞争能力。机械工业部制订了JB 2281-78《机床噪声测量方法》标准,机床行业各工厂一般都制订了相应的厂内验收标准。 机床噪声源一般不只是一个,在有多个噪声源又无足够分析仪器的情 Noise is an important quality indicator of machine tool products, which directly affects the health of operators and the competitiveness of machine tool products in the international market. Ministry of Machinery Industry has developed JB 2281-78 “machine noise measurement method” standard, the machine tool industry factories have generally formulated the corresponding factory acceptance criteria. Machine noise sources are generally not just one, there are not many sources of noise and not enough analytical instruments
