Vibration Processing

Vibration Processing

 

a method of mechanical or chemical-mechanical processing of parts and blanks involving smoothing of microscopic irregularities and removing particles of material from the work surface by an abrasive medium that is vibrated (in the frequency range of 10 megahertz to 10 kilohertz) by the action of a chamber containing the workpieces and the processing medium. The processing takes place in a dry medium or in a solution, which may contain various chemical additives.

Vibration processing is used to clean castings, to remove scales and the products of corrosion from the surface of blanks and parts, to remove burrs and round off sharp edges, to eliminate flash from castings and stamped and pressed parts, to improve the grade of surface finish (vibration grinding), and to prepare surfaces for galvanizing and painting, decorative polishing, and other types of finishing. Vibration processing also equalizes the stresses in the surface layers of a metal and strengthens them through work hardening.

In this study, a series of oil extraction and emulsion experiments under low frequency vibration processing were performed to explore the effect of the synergistic mechanisms about low frequency vibration processing and surfactants.
Because when the oil sand has higher oil ratio, the adhesion strength between oil and sand is so strong that it is difficult to destruct the work of adhesion under low frequency vibration processing in a short time.
It can be learned that the capacity of the surfactant to emulsify the crude oil improves under low frequency vibration processing and the volume of the emulsification with low frequency vibration processing is about 5 times more than that without low frequency vibration processing.
Fig 5 shows two photographs of the O/W emulsion as prepared by two conditions through an optical electron microscope at magnification 160 The emulsion pellets diameters with low frequency vibration processing is about 1/3 times of that without low frequency vibration processing, and the density of emulsion pellets under low frequency vibration processing is about 2 times of that without low frequency vibration processing.
Fig 6 shows the emulsion state of two colorimetrical cylinders in the right direction of ray under low frequency vibration processing and without low frequency vibration processing at a certain time.
An advantage of melt vibration processing is that it can be specifically programmed to induce improvement in a given characteristic of the molded part, e.
The know-how relates to the determination of the best melt vibration processing parameters for a given resin.
If and when the model is capable of integrating all the effects of vibration on viscosity and morphology, at macroscopic and microscopic levels, it will be possible to determine the optimum melt vibration processing conditions without recourse to an excessive number of experiments.
The system, which would incorporate temperature, speed, and pressure sensing along with vibration processing, is now undergoing feasibility testing.
