PRODUCT OVERVIEW
DZ703 EDM Drilling Machine Overview
The DZ703 EDM Drilling Machine is designed for precision electrical discharge drilling of electrically conductive workpieces. EDM drilling is suitable for producing small and deep holes where conventional mechanical drilling may be difficult because of material hardness, hole depth or workpiece geometry.
The DZ703 provides 400 × 300 mm X/Y-axis travel and 300 mm Z-axis travel. A 420 × 320 mm worktable supports workpieces with a listed maximum load capacity of 200 kg.
The machine features a 360 mm secondary spindle stroke and supports electrode clamping diameters from Ø0.3 mm to Ø3.0 mm. The specified processing depth is 0–300 mm.
According to the supplied specification, the DZ703 provides a maximum processing speed of 60 mm/min, a maximum processing current of 30 A and a working pressure of 8 MPa.
The working fluid can be tap water or distilled water, with a 45 L working fluid tank. The machine uses grating-rule DRO for X/Y-axis positioning, subdivision stepping motor control for the Z axis and AC reduction motor control for the secondary spindle stroke.
