PT Journal AU Zarnovsky, J Kovac, I Mikus, R Fries, J Mosat, M TI Vibration Diagnostics of CNC Machining Center Spindle SO Manufacturing Technology Journal PY 2019 BP 350 EP 356 VL 19 IS 2 DI 10.21062/ujep/295.2019/a/1213-2489/MT/19/2/350 DE Vibrations; diagnostics; spindle; device; speed AB The principle of vibrodiagnostics lies in the appropriate measuring and analysis of mechanical vibrations of machinery and constructions in industrial and laboratory environment.The aim of this paper is to perform diagnostic measurements on the most essential parts (spindles) of machinery devices Semico VCM 1000. Measurements were carried out by means of portable vibrodiagnostic measuring device Adash A4900 vibrio M. Vibrodiagnostic itself was realized as a walk-monitoring of machinery state according to corresponding technical standard ISO 10816-3:2009, and of limit values, which took place at regular intervals in the selected organization.
