SD-750 CNC Microhole Drilling EDM Machine
Guidance from Steve Brown, EDM Specialist, Iron Machine Tool
CNC Hole Popper EDM for Repeatable, High Accuracy Production Drilling
The Mitsubishi SD-530 is a CNC hole popper EDM machine engineered for manufacturers that need fast, repeatable hole drilling across production volumes where manual operation is no longer efficient. Equipped with a standard 10-position automatic electrode changer and a 4-position automatic guide changer, the SD-530 eliminates manual electrode swaps and reduces operator involvement between cycles. It burns precise holes through hardened steel, carbide, and other conductive materials, making it a reliable CNC hole popper EDM solution for mold makers, die shops, and precision manufacturers across Minnesota and the wider Midwest.
How the SD-750 Handles Microhole Drilling at Production Scale
The SD-750 uses a rotating tubular electrode and controlled electrical discharge to erode material and burn holes through hardened metals without mechanical stress or tool deflection. Its 15-position automatic electrode changer, the largest standard changer in the Iron Machine Tool EDM hole drilling lineup, keeps microhole drilling programs running across long electrode life cycles without operator interruption.
The 4-position automatic guide changer ensures consistent guide positioning across the full electrode diameter range, maintaining hole-to-hole accuracy even on complex multi-hole programs. Coolant flushes debris from each hole continuously, producing clean walls and reliable dimensional accuracy across every hole in the program. For manufacturers running demanding micro hole EDM drilling work on large tooling, the SD-750 delivers the combination of travel, automation, and speed that smaller CNC hole poppers cannot match.
SD-750 CNC Machine Specifications
The SD-750 offers the largest worktable travel in the Iron Machine Tool CNC hole popper EDM lineup, with an XY envelope suited to large mold bases and tooling plates. Its electrode travel, guide travel, and table-to-guide range accommodate deep hole work across a wide variety of workpiece geometries, while the standard 15-position electrode changer handles full production runs without manual restocking between cycles.
