Quick discharging method of material to be removed in electric spark machining

Abstract

The invention relates to a method for acceleratively expelling removed materials in the process of processing fine deep holes by electric sparks, belongs to the field of mechanical manufacture, and in particular relates to a method for acceleratively expelling the removed materials in the process of processing the fine deep holes by the electric sparks. In the process of processing the fine deep holes by the electric sparks, when ultrasonic vibration is applied to a workpiece or a tool electrode, the method also makes the tool electrode and the workpiece carry out periodic relative movement and uses two modes for assisting processing simultaneously so as to acceleratively expel the removed materials in a processing region. The application of the ultrasonic vibration has two modes, namely the ultrasonic vibration to the workpiece or the ultrasonic vibration to the tool electrode, so that the periodic relative movement between the tool electrode and the workpiece also has two modes. In the process of processing the fine deep holes by the electric sparks, the method accelerates to expel the removed materials smoothly from the processing region, thereby improving processing quality and processing efficiency. The method is suitable for processing fine deep holes in any cross section shape.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to a method for accelerating the discharge of removed materials in the process of electric discharge machining fine deep holes. Background technique [0002] In order to discharge the removed material smoothly in EDM, the usual method is to forcibly discharge the removed material in the processing area by means of circulating machining fluid, but as the hole depth increases, it is difficult for the machining fluid to enter the hole, making this method difficult to work . In this case, an additional measure, such as applying ultrasonic vibrations to the workpiece or tool, or shaking the tool, is often used to facilitate the removal of the removed material. Even so, it is still difficult for the material to be removed to be smoothly discharged when the fine deep hole is machined by the electric discharge method. These removed materials are suspended in the machining fluid in ...

Problems solved by technology

Even so, it is still difficult for the material to be removed to be smoothly discharged when the fine deep hole is machined by the EDM method.

These removed materials are suspended in the machining fluid in the form of tiny particles, and are often non-uniformly distributed in the discharge gap, which can easily lead to local short circuits or abnormal discharge, resulting in a decrease in processing quality and efficiency, and even making the processing difficult. keep going
