Overview
The Sodick AP250L is a compact precision wire EDM from Sodick's AP series, engineered for oil-dielectric machining of motor cores, lead frames, electronic component dies, and precision stamping tooling. With 250 x 150 x 120 mm X/Y/Z travel and a maximum workpiece weight of 80 kg, the AP250L targets applications where ultra-fine wire capability and oil-based dielectric cutting produce results that water-dielectric machines cannot match. The machine supports wire diameters from 0.03 to 0.20 mm, extending into the micro-wire range.
The AP250L employs Sodick's linear motor drive architecture with a gantry-type construction, delivering frictionless, zero-backlash positioning. The 5th-generation EDM Perfect Active Control technology manages spark discharge with fine energy resolution across the full range of ultra-thin wire diameters, critical when cutting with 0.03-0.05 mm wire where discharge energy must be precisely controlled to prevent breakage.
Oil dielectric machining on the AP250L provides advantages over water dielectric for certain precision applications: no workpiece corrosion risk, no electrolysis-related surface contamination, and superior surface finish on materials sensitive to water-based dielectric chemistry. This makes the AP250L particularly valuable for copper alloy lead frames, magnetic core laminations, and precision connector tooling.
The work tank inner dimensions of 895 x 740 mm accommodate workpieces up to 400 x 270 x 100 mm during flushing. At 3,730 kg machine weight and 1,860 x 2,515 mm footprint, the AP250L fits into existing shop floor layouts without major facility modifications.

Strengths & Limitations
Strengths
- Ultra-fine wire capability down to 0.03 mm enables micro-features impossible on standard wire EDMs
- Oil dielectric eliminates workpiece corrosion, electrolysis, and water chemistry surface effects
- Linear motor drives with gantry construction provide zero-backlash positioning for micro-precision work
- 5th-generation Perfect Active Control precisely manages spark energy for ultra-thin wire
- Compact 3,730 kg footprint fits existing shop layouts without major facility modifications
- 1 Gbit/sec serial communication ensures high-speed generator-controller interaction
Limitations
- 250 x 150 mm X/Y travel limits the machine to small-format precision work only
- 80 kg workpiece weight limit restricts to lightweight precision components
- Oil dielectric requires fire suppression and enhanced ventilation provisions
- Plus/minus 7 degree taper is more restrictive than standard wire EDMs

Frequently Asked Questions
01
Oil dielectric eliminates workpiece corrosion, electrolysis contamination, and water chemistry surface effects. For motor core dies, lead frame tooling, and connector dies where surface integrity affects part quality, oil produces cleaner cuts with fewer post-processing requirements.
02
With 0.03 mm wire (30 microns), the AP250L can produce features approaching 40-50 microns in width depending on skim passes and material. Practical minimum depends on wire diameter, workpiece thickness, and required accuracy.
03
The AP series uses oil dielectric and supports ultra-fine wire down to 0.03 mm for precision electronic and motor core die work. The AQ series uses water dielectric with 0.10-0.30 mm wire for general-purpose die and mold work with larger travel envelopes.
04
Regular dielectric fluid monitoring, periodic fluid replacement, filter element changes, and temperature control maintenance. Oil systems also require fire suppression and ventilation provisions.
