Description

Fine blood discharge processing device {A SMALL HOLE ELECTRIC DISCHARGE MACHINE}

The present invention relates to a blood vessel discharge processing apparatus of the workpiece precipitation type.

To explain this in more detail, at the rear of the upper surface of the workbench installed at the upper side of the cabinet, a position adjusting carriage formed of a transport zone of X, Y, and Z axes is installed, and a processing tank equipped with a work table is installed at the front, In the upper side and the lower end of the Z-axis feeder to be formed in the electrode rod tube and the electrode guide tube mounted on the same vertical line;

In the outer side of the electrode guide pipe provided at the lower end of the Z-axis feeder, a centralized injection nozzle of the processing liquid is formed integrally, and the processing liquid is sprayed vertically downward through the processing electrode during discharge processing. The processing liquid sprayed downwardly through the central concentrated spray nozzle forms a water curtain (water curtain) to prevent scattering and prevents discharge in the air during initial discharge processing, and the processing liquid circulated to the lower side of the workpiece during penetration Blocks (oxygen) to induce normal discharge, and is supported by holding the processing electrode rod which is supplied with the processing electrode guide device between the electrode rod tube installed on the Z-axis feeder and the processing liquid injection nozzle assembly. It gradually lowers and prevents the bending of the processing electrode during discharge processing, so it can be processed quickly and precisely. It will be to provide an improved electrical discharge machining device to be sehyeol.

Fine-grained discharge of the workpiece sedimentation type is finely squeezed out of very hard samples (materials) such as cemented carbide and quenched high-speed steel and heat-resistant steel while passing the processing liquid at high pressure through the process electrode formed in the shape of a thin pipe. It is a device used to drill).

As a conventional blood-discharge processing apparatus for use in drilling a blood (fine hole) into a sample (material) having a very high hardness as described above, the patent application No. Fine deep hole discharge processing machine freely change the position of the head portion, and "CNC thin blood discharge processing machine" of Patent Registration No. 10-564159 and "Discharge processing device" of Patent Registration No. 10-571025.

In addition, a phenomenon in which the electrode electrode 23 is deformed due to instantaneous heating of the electrode electrode 23 is generated. As a result, a phenomenon in which the outer diameter of the electrode electrode 23 is deformed (increased) occurs. Since the processing liquid is injected through the inner diameter of the electrode 23, in-air discharge is indispensably generated from the outside of the processing electrode 23.
