Air regime and assessment of working environment factors in precision processing of non-ferrous metal components

Abstract

Technical modernization of production requires hygienic evaluation of occupational factors at workplaces of coldpressing equipment adjusters, with the equipment evaluation. Production of memorable, jubilee coins and badges requires hi-tech equipment and special attention to the output products quality. The authors assessed air enviornment and occupational environmental factors in coining of non-ferrous articles at workplaces using cold-pressing equipment. Increased concentrations of mineral oils could result in damages of working surface processed and deteriorate the output article quality. Electrostatic field increases the surface damage effect due to absorption of dust particles from ambient air. The recommendations specifi ed enabled to increase quality of the output articles due to removing dust from the air feed and lower accumulation of electrostatic charge on the working surface, reliable grounding of devices.
