随着工业生产和科学技术的迅速发展,许多工厂都采用了电火花技术进行材料的尺寸加工,大大提高了生产效率和加工质量。由于这是一门新的工艺,国内外对其劳动卫生问题研究得不多,这就从科学研究和实际应用上给我们提出了新课题。为此,我们在上海机电一局的支持下,对国内应用较广的电火花工艺(电脉冲、电火花)进行了劳动卫生的初步调查。 With the rapid development of industrial production and science and technology, many factories have adopted the EDM technology for material size processing, greatly improving the production efficiency and processing quality. Since this is a new craft, there are not many studies on its labor and health problems both at home and abroad, which have raised new topics for us from scientific research and practical application. For this reason, with the support of Shanghai Mechanical & Electrical Industry Bureau, we carried out a preliminary investigation on labor hygiene in the widely used EDM process (electric pulse, spark) in China.
