Problem VibroMatrix is used as the measuring system for monitoring. The listed monitoring features were implemented in a specially configured setup. This does not only allow a general recognition…
Problem The fine processing of optical glass requires highest precision. Disturbances caused by imbalance and bearing damage must be avoided at all costs. In order to guarantee a permanently…
Problem On a CNC travelling column milling machine, chatter marks occurred at a spindle speed of 1300 rpm (21.7 Hz). The measurement was carried out directly on the main spindle using an…
Problem The investigation was caused by increased operating noises and vibrations at an exhaust system. The fan was driven by a belt (motor speed 2988 rpm, fan speed 1902 rpm). The vibration…
Problem An increased vibration acceleration in the frequency range 1..10 kHz was detected at a bearing during a regularly measurement. Periodic peaks with amplitudes of up to 40 m/s² were detected…
Problem These wide high-frequency excitations and clear black deposits near the bearing indicated a completely defective bearing. This was confirmed after disassembly of the bearing: The bearing…
The spindle of a machining center should be balanced during maintenance work. For this purpose, all balancing measures of the previous balancing procedures were reversed (grub screws removed).…
During a regular measurement, the fan for ventilation of a rotary kiln was examined. The 900 mm rotor was driven by a 143 kW electric motor. At an operating speed of 3000 rpm, a vibration velocity…
