EDM Machine Packaging

An EDM machine ships with a problem most crating firms never plan for: a dielectric tank that must be fully drained and declared before it can leave the plant, a servo head set to micron gap control, and, on sinker machines, graphite or copper electrodes that chip like glass. BENZ handles the fluid, the declaration and the precision as one job, on site.

The challenge

The dielectric fluid is the export problem nobody plans for until customs stops it.

A sinker EDM machine's work tank holds a hydrocarbon-based dielectric oil, a flammable liquid that cannot travel in the tank and must be fully drained, the tank purged, and the machine declared clean before it is packed, or the shipment gets flagged and held at origin or destination customs as undeclared hazmat. A wire EDM machine instead runs deionised water through a filtration and resin-bed system that, if left wet, corrodes the brass wire guides, the flushing nozzles and the tank internals from the inside where nobody sees it until the buyer opens the machine.

Underneath that fluid problem sits a precision one. The Z-axis servo head positions the electrode to a gap measured in microns, and on sinker machines the electrodes themselves, graphite or oxygen-free copper, are machined to the cavity's exact form and chip or crack if they knock against anything harder than foam. BENZ drains and certifies the machine clean, protects the servo head and guides, and cases the electrodes as separate precision tooling, exactly as we do with the hobs on a gear machine.

How we pack an EDM machine

Fluid handled first, precision protected next

Drain and purge the dielectric system

The work tank, filtration unit, resin bed and all fluid lines are fully drained, and on sinker machines flushed to remove residual oil, so the machine ships dry and can be honestly declared on the export paperwork with no hazmat exposure at customs.

Case the electrodes and wire spool separately

Graphite and copper electrodes are wrapped individually and packed in slotted foam tool cases so cavity-form edges never contact anything hard; the wire spool and guide assemblies on wire EDM machines are secured against unwinding and shock.

Protect the servo head, tank and control cabinet

The Z-axis head, worktable and tank interior are preserved with VCI vapour-phase protection to MIL-PRF-3420H, the control and generator cabinet is cushioned against its own mass, and the assembly is sealed in a moisture barrier envelope with desiccant for sea freight.

Skid, crate and load-secure

An engineered skid built to the machine's weight and tank position, calculated cushioning at every contact point, and a heat-treated ISPM-15 crate designed for crane lift and safe container stacking.

Frequently asked

EDM machine packaging: questions

How do you pack an EDM machine for export?

We fully drain and purge the dielectric tank and fluid lines so the machine can be honestly declared free of hazardous residue, case the electrodes and wire spool as separate protected tooling, preserve the servo head, tank and control cabinet with VCI and a moisture barrier seal, then mount the machine on an engineered skid inside a heat-treated ISPM-15 crate.

Does the dielectric oil in a sinker EDM machine need to be drained before shipping?

Yes, completely. Dielectric oil is a flammable liquid and cannot travel in the tank. We drain and purge the tank and lines on site and provide the paperwork confirming the machine is clean, which avoids a hazmat hold at export or import customs.

How do you protect EDM electrodes during transit?

Graphite and copper electrodes are removed where practical, individually wrapped and packed in slotted foam tool cases so their machined cavity form never contacts the machine casting, other electrodes or anything hard enough to chip them.

Do you pack wire EDM and sinker EDM machines differently?

Yes. Sinker EDM centres on oil tank draining, hazmat-safe declaration and electrode protection, while wire EDM centres on flushing the deionised water and resin-bed system and securing the wire guides and spool, since leftover water corrodes brass guides from the inside.

Do you pack EDM machines on site at our factory?

Yes. A BENZ team comes to your plant with fluid-handling equipment, tooling and lifting gear, drains and packs the machine on your shop floor, and removes the drained fluid per your site's disposal process.

Are your EDM machine crates ISPM-15 compliant?

Yes. All solid-wood crating and skidding is heat-treated and ISPM-15 stamped, with the treatment certificate supplied for customs clearance without quarantine or fumigation.
