Electrical Discharge Machine

An electrical discharge machine, enabling to be equipped with a dielectric fluid to perform electrical discharge machining on a workpiece, and the electrical discharge machine comprising:

• a droplet processing cavity, providing a processing dielectric environment for the workpiece and comprising a cavity tool channel;
• an atomization device, receiving the dielectric fluid and atomizes the dielectric fluid to generate a dielectric droplet, and the atomization device is connected to the droplet processing cavity to provide the dielectric droplet to the processing dielectric environment;
• an EDM tool, comprising a tool body, a tool machining structure, and a tool inner flow channel, and the tool machining structure is located on the outside of the tool body, and the tool inner flow channel is located inside the tool body and extends through the tool body;
• an EDM spindle used to install the EDM tool, allowing the EDM tool to enter the droplet processing cavity through the cavity tool channel, and the EDM spindle can also move the EDM tool to bring it close to the workpiece within the droplet processing cavity, forming an EDM discharge channel between the tool machining structure and the workpiece;
• and
• a negative pressure providing module connected to the tool inner flow channel, allowing the negative pressure providing module be able to provide negative pressure suction through the tool inner flow channel to create a negative pressure flow field in the EDM discharge channel, forming the fluid driving the dielectric droplet via the negative pressure flow field, thereby driving the dielectric droplet into the EDM discharge channel, allowing the tool machining structure to perform electrical discharge machining on the workpiece in the EDM discharge channel, and then the negative pressure flow field can drive the dielectric droplet out of the EDM discharge channel through the tool inner flow channel.
