PRODUCT OVERVIEW

DK703 EDM Drilling Machine Overview

The DK703 EDM Drilling Machine is designed for precision electrical discharge drilling of electrically conductive workpieces. The EDM drilling process is particularly useful for producing small and deep holes in hard conductive materials where conventional mechanical drilling may be difficult.

The DK703 is equipped with a 330 × 480 mm worktable and provides 200 × 300 mm work surface travel. Its compact machining range makes it suitable for precision components, tooling, mold and die parts and start-hole drilling applications.

The machine features a 280 mm spindle head stroke and 300 mm servo travel. According to the supplied specification, the DK703 supports electrode diameters from Ø0.3 mm to Ø3.0 mm.

The maximum processing speed is specified at 40 mm/min, with a maximum depth-to-diameter ratio of 300:1. Pure water is used as the working fluid, with a specified working pressure of 7 MPa.

The supplied specification also lists a maximum machining current of 30 A, maximum power consumption of 3 kVA and automatic Z-axis control.
