Small-Hole EDM Drilling Machine

S Series Economy Model GD-430S

Description

CNC small-hole EDM machine. The operating interface software can be customized to meet different machining requirements. Drawing on extensive expertise in small-hole EDM operation and machine characteristics, it delivers high accuracy in hole diameter and verticality. It can machine conductive materials with hole diameters from 0.2 to 3.0 mm; tests have achieved holes as small as 0.15 mm. This overcomes many conventional machining limitations and enables machining of ultra-hard alloys, spherical surfaces, inclined surfaces, and other workpieces.
