Sodick Sodick AP350L

The Sodick AP350L is a mid-size oil-dielectric wire EDM from the AP series, offering 350 x 350 x 120 mm X/Y/Z travel for precision machining of motor cores, electronic component dies, and stamping tooling where oil-based cutting provides superior surface integrity over water dielectric. With a maximum workpiece weight of 100 kg and workpiece dimensions up to 540 x 500 x 100 mm during submerged machining, the AP350L provides a larger work envelope than the AP250L while maintaining fine-wire capability.

The AP350L supports wire diameters from 0.05 to 0.25 mm and employs Sodick 4-axis linear motor drives with a gantry structure for frictionless, zero-backlash positioning. The machine precision is particularly evident in motor core die applications, where lamination punch-to-die clearances measured in single-digit microns demand positioning accuracy that ball-screw machines cannot reliably maintain.

Oil-dielectric machining eliminates the corrosion, electrolysis, and surface contamination effects that water dielectric causes on copper alloy, magnetic steel, and other sensitive die materials. The machine achieves plus/minus 7 degree taper at 100 mm plate thickness, adequate for motor core and electronic component tooling.

At 4,650 kg machine weight and 1,985 x 2,095 mm footprint (3,705 x 3,515 mm installation space), the AP350L fits into precision die shops without major facility modifications. Three-phase 13 kVA power is required.
