Abstract
The invention discloses an ultrasonic dressing system for a metal-based grinding wheel. An ELID (electrolytic in-rocess dressing)-ultrasonic dressing system for the metal-based grinding wheel effectively solves the problem that the electrolyte distribution between a dressing electrode and the grinding wheel in the traditional ELID grinding technology is not uniform, so that the abrasive particles after dressing the grinding wheel are exposed uniformly, and the quality of the ELID grinding surface is improved. Simultaneously, an ultrasonic vibrating electrode is introduced to increase the electrolytic mass transfer efficiency, and the ion concentration on the surface of the grinding wheel is improved, so that the oxide film is uniform and compact in distribution. When the electrode vibrates in an ultrasonic manner, the electrolyte cavitation is caused, so that the cavitation energy further quickens the removing of the bonding agent on the surface of the grinding wheel, and the dressing efficiency of the grinding wheel is increased. Therefore, the ELID-ultrasonic dressing technology has better electrolytic dressing quality and higher dressing efficiency relative to the traditional ELID technology, and has positive significance to improve the ELID grinding surface quality and improve the ELID grinding efficiency.

The ELID grinding technique has the advantages such as device is simple, and manufacturing is installed easily, and cost is lower, is widely used in the superfine grinding field of difficult-to-machine material, hard brittle material.But the close clearance between electrolysis electrode (negative electrode) and the Metal Substrate emery wheel (anode) is so that the flow effect variation of electrolyte, so that the electrolyte skewness between emery wheel and electrolysis electrode, distribute more at the electrolyte that flows into end, and distribute less at outflow end electrolyte, thereby cause the problems such as the wheel face electrolysis is inhomogeneous, wheel face abrasive particle ride out does not wait, the oxide-film covering is inhomogeneous, be difficult to obtain very high surface quality when causing superfine grinding.
For solving the poor problem of flow effect between electrode and the emery wheel, there is the researcher to propose the electrode of special internal shape according to fluid mechanics principle, to improve the flow regime of electrolyte, the method has been improved the electrolyte flow state between electrode and the emery wheel to a certain extent, but still has the problems such as electrolyte skewness, the emery wheel electrolysis is inconsistent, the oxide-film distribution is inconsistent.
The researcher is also arranged along emery wheel and a plurality of nozzles of electrode circle distribution, simultaneously to wheel face jet electrolytic liquid, effectively alleviated electrolyte problem pockety.This technology nozzle increases the outlet flow regime of improving electrolyte, but electrolyte cavity volume electrolyte inside flow regime each nozzle place go out water speed, flow has very large difference, causes electrolyte inhomogeneous along the gap distribution of emery wheel and electrode.Therefore electrolyte is not solved in the inner skewness problem of electrode gap at all.
Summary of the invention
The present invention is directed to the emery wheel that exists in the existing ELID grinding technique and the electrolyte skewness between the electrolysis electrode, distribute more at the electrolyte that flows into end, and distribute less at outflow end electrolyte, thereby cause that the wheel face electrolysis is inhomogeneous, wheel face abrasive particle ride out does not wait, oxide-film covers the problems such as inhomogeneous, be difficult to when causing superfine grinding obtain the very high problems such as surface quality, propose a kind of ultrasonic dressing of ELID-system of Metal Substrate emery wheel.
The present invention is achieved in that a kind of ultrasonic dressing system of Metal Substrate emery wheel, it is characterized in that, described ultrasonic dressing system comprises:
