Vibratory Stress Relieving Machines, known as 'Formula 62' Machines in the market, are widely used in more than 74 countries in over 1000 different types of Companies. Vibratory Stress Relieving Machines use resonant vibration to take full advantage of both resonance peak growth and/or shifting type responses that occur during effective vibratory stress relieving the only method which can assure dimensionally stable, and therefore, predictable work pieces. Resonant vibrations have been found to be the most effective means for reducing residual stresses by vibration. The resonant frequency vibration method has a much more pronounced stress redistribution compared to the sub resonant (sub harmonic) frequency methods. High amplitude resonant vibrations are very efficient in significantly reducing peak residual stresses in weldments. Low frequency vibrations are used as a carrier to deliver high amplitude energy to a metal fabrication, or machined part. The heavy vibrations produce a load that is superimposed on the existing stress patterns that result in a reduction of peak residual stresses. This produces a more dimensional stability product and reduces the random distortion that often occurs in unstable work pieces.
Features

Uses
- The process can be used on a wide range of ferrous and non-ferrous metals.
- Typical materials can be treated like carbon steels, stainless steel, aluminum, cast iron, manganese, incolnel, etc.
- Into a variety of conditions such as: wrought or cast, forged, formed, welded, ground, polished or machined.
