The basic task of any prosperous company is to minimize operating costs to a minimum. High-quality maintenance ensures an increase in the operational reliability of the machines. It is important to find a compromise between scheduled maintenance and production process requirements, so resources are spent to optimize the maintenance schedule. This is provided by technical diagnostics, which helps to monitor the technical condition and functional properties of the monitored machine under specified operating conditions. The publication is focused specifically on vibration diagnostics and its use in monitoring the transmission of vibrations during the turning of selected types of materials in the company with a focus on engineering, the ZVL AUTO s.r.o. The scope of research is mainly focused on the monitoring process in order to analyze the magnitude of vibration acceleration at two preselected parts of the machine tool - lathe.
