Many factories are making the switch to Predictive Maintenance. This usually includes implementing Oil Analysis and Vibration Analysis programs. Due to the high set-up costs and the required expertise, most factories choose to schedule external Vibration audits on a monthly/quarterly basis.
A typical audit costs $30-$60 for one machine recording and the analysis can take 7-10 days. Due to the high costs and inflexibility, facility managers basically lose control over their vibration analysis program.
