Abstract

The main goal of observing vibrations of rotating parts is to get information on the operational and technical status, with the goal of securing strategic planning and maintenance management. An important part of this process becomes the assessment of the status and progression of vibrations during the use of given machine. It is necessary to bear in mind that vibrations on rotating machines are closely related to dynamic straining parts like e.g. bearings, gears. In the experimental section, sizes of vibration amplitudes have been measured on the head of a pillar drill. During the measurement the tool as well as rotation speed of the devices were changing. The results are processed in table and graphics form. In the conclusion of this paper, recommendations are stated for input factors used for measurement and processing using the drilling technology
