Application of technical vibrodiagnostics in the context of predictive maintenance of industrial machines

Scientific research was conducted when using application of technical diagnostics and vibrodiagnostics, when testing and analysis of vibrations and stresses of the machine tool with diagnostic device, on example of automatic industrial grinding machine of grey and nodular castings (Koyama). Basic goal of this research was measuring and analysis of vibration of the machine and determination of tool stresses during cutting and grinding cycles. By means of diagnostic device Fixturlaser SMC, were analysed key characteristics such as: speed vibration, acceleration and balancing of the main circular. Furthermore, the paper emphasizes importance in protective maintenance for the prevention of origin of damage and increase efficiency, as well as preservation of the workers’ health. Also are explained theoretical basics of vibrations, methods of measurements, and analysis and data processing by using contemporary diagnostic tools. Shown practical results were done through measurements on casting model 21005034, including technical description of the machine, tools, and diagnostic devices. In conclusion, the research emphasise application of technical vibrodiagnostics in context of savings, reductions of standstill and faults, as well as increase in productivity.
