Equipment Introduction

The machine is a high-speed EDM small hole machining equipment. Copper tube is used as the electrode and guided by the guide device. The high-efficiency pulse power supply is applied between the electrode and the workpiece. During the processing, the spindle drives the electrode to make servo feed under the control of the servo system. Pulse high-frequency discharge is generated between the electrode and the workpiece to control the workpiece erosion. In the process, high-pressure water working fluid is ejected from the inner hole of the electrode, and the forced chip removal cooling is implemented on the processing area to ensure the smooth processing.

Equipment Features

This kind of technology processing aperture range is generally in φ 0.2-3 mm, the maximum depth diameter ratio of about 1 mm can reach 300:1 or more, and the processing speed is generally 1-40 mm / min. It can directly penetrate through the inclined plane and curved surface, and is not limited by the hardness and toughness of the material. In addition to processing ordinary conductive materials, it can also process stainless steel, cemented carbide, quenched steel, high temperature heat-resistant alloy and copper smoothly Alloy, titanium alloy and other conductive materials difficult to machine.
