Product Description

300x400 mm Worktable Travel Edm Hole Drilling Machines SK703-3040 Edm Drill Machine
 

This machine is a high-speed EDM equipment with small holes. The copper tube is used as the electrode and guided by the guide. A high-efficiency pulse power supply is applied between the electrode and the workpiece. In the process, the Spindle-driven electrode is servo-fed under the control of the servo system, and pulse high-frequency discharge is generated between the electrode and the workpiece, which can control the erosion of the workpiece. In the process, the high-pressure water quality working fluid is ejected from the inner hole of the electrode, and the chips are forced to be discharged and cooled in the processing area to ensure the smooth processing. Machining aperture range is generally in the range of 0.2-4. The depth-diameter ratio of the aperture is about 1 mm can reach 300:1, and the processing speed is generally 1-40/min. It can penetrate directly from the inclined surface and surface without the limitation of hardness and toughness of the material. CNC EDP is a set of advanced functions such as Z-axis deep precise processing, X-axis and Y-axis servo detection, and it is easy to use and operate. Single, stable, reliable, wide range of applications and other characteristics of products. It can be used for deep and precise small holes which are difficult to be machined by many traditional processing methods, such as cutting perforation, blowhole, group holes and nozzle holes of various metals and super-hard conductors.
