Industrial Noise & Vibration Centre Ltd
The purchaser of several multi-spindle auto lathes was on the point of cancelling the order as the first completed machines did not meet the agreed noise level of 83 dB(A) (3000 rpm) – they were typically generating 87 – 90 dB(A). We used the results of sophisticated noise and vibration analysis to recommend a change in the assembly procedures used that reduced noise levels to <83dB(A) at negligible cost.
The diagnosis and recommendations were completed in less than 2 days and, as a result, all purchasers now receive quiet machines. This illustrates the benefits of effective policing of purchasing requirements.
