Problems solved by technology

However, like the dry EDM method, the quasi-dry machining method has a complex auxiliary air supply booster system, and the peripheral equipment is huge and complicated, which is not conducive to stable processing for a long time
At the same time, the working fluid particles produced by this method are not uniform and have poor continuity, which seriously affects the processing effect in precision machining.

Abstract

The invention provides an ultrasonic spray near drying type electrical discharge machining method. According to the method, electrical discharge machining is conducted on a workpiece through an electrical discharge machining device, and meanwhile auxiliary ultrasonic spray machining is conducted on the workpiece through an ultrasonic spray device. The invention further provides an ultrasonic spray near drying type electrical discharge machining device. The ultrasonic spray near drying type electrical discharge machining method and device have the advantages that electrical discharge machining is conducted while ultrasonic spray is conducted on working liquid, high-energy frog drops with particles being evenly distributed can be obtained through ultrasonic spray, the material removal rate is increased through the ultrasonic cavitation generated in the ultrasonic spray process, and machining efficiency and the machining effect are improved.

Description

technical field [0001] The invention relates to electrical discharge machining, in particular to a quasi-dry type electrical discharge machining method of ultrasonic spraying and a device thereof. Background technique [0002] EDM is also called Electrical Discharge Machining (EDM for short). Its machining process is to use the pulse power supply to continuously generate electric pulses, and to form a discharge on-off by breaking down the working medium between the tool electrode and the workpiece. The heat generated during the process will erode the workpiece and process it into the desired shape. Therefore, EDM is not limited by mechanical properties such as the strength and hardness of the workpiece material, and can process any conductive material. At the same time, because the tool electrode does not contact the workpiece material, it is easy to realize the molding of complex shapes such as thin walls, narrow grooves, curved holes, and cavities, and is also suitable fo...
