AD6L CNC Submerged Micro EDM Machine
Guidance from Steve Brown, EDM Specialist, Iron Machine Tool
Highest Precision CNC Submerged Micro EDM for Complex Microhole Drilling
The Mitsubishi AD6L is a CNC submerged micro EDM machine engineered for manufacturers that demand the highest precision in microhole drilling and micro EDM work on hardened steel, carbide, and other conductive materials. Unlike conventional hole popper EDM machines, the AD6L fully submerges the workpiece during the micro EDM process, eliminating thermal variation and delivering cleaner, more consistent microholes across every cycle.
With configurable 10 or 20-position automatic electrode changers, 5 to 20-position automatic guide changers, and optional 5th or 6th axis rotary and tilt-turn table configurations, the AD6L handles complex micro EDM drilling programs that no other machine in the Iron Machine Tool EDM hole drilling lineup can match. It is the definitive choice for precision manufacturers across Minnesota running demanding micro EDM and microhole drilling applications.
How Submerged Micro EDM Delivers Superior Microhole Accuracy
Conventional CNC hole popper EDM machines operate with coolant flushing the electrode and hole from above. The AD6L takes a fundamentally different approach: the entire workpiece is submerged in dielectric fluid during the micro EDM process. Full submersion eliminates the thermal gradients that cause dimensional variation in standard hole popper EDM, keeps the discharge zone stable throughout every cycle, and produces microholes with superior wall finish and tighter dimensional tolerances than conventional EDM hole drilling can achieve.
For manufacturers working with microholes where even minor dimensional variation is unacceptable, submerged micro EDM is the process standard. The AD6L delivers that standard with CNC automation, configurable electrode and guide changers, and optional multi-axis rotary table configurations for complex workpiece orientations.
AD6L CNC Machine Specifications
The AD6L combines a mid-range XY travel envelope with deep electrode and guide travel, sized for precision tooling and complex mold components rather than large format plates. Its configurable electrode and guide changer positions, and optional 5th and 6th axis table options, give the AD6L a flexibility that no fixed-configuration CNC hole popper can match, making it adaptable to the widest range of micro EDM and microhole drilling programs in the lineup.
