When it comes to mass finishing, amplitude and frequency require balance and careful consideration. Amplitude is a measure of movement and intensity while frequency refers to the rate of repetition.
The wrong amplitude, for example, can create lackluster finishing results and longer processing times if it is too low. If too high, it can cause unnecessary wear and tear on the machine.
Creating Vibratory Energy
Whether rotary or tub style, mass finishing vibrators always include two key components: a work bowl containing the finishing media and the work pieces.
Firmly attached to this work bowl is a vibratory drive system generating the energy to put the media and work pieces in motion. The work bowl with an attached vibratory drive system sits on a number of coil springs – in some cases on air cushions – which in turn sit on a machine base. The springs, respectively, act as air cushions allowing the work bowl to “free float” up and down within a certain distance.
