Selling a wire EDM machine with its supporting equipment

Use a simple diagram as an inventory aid. Replace the example labels with the make, model and asset reference of the equipment on site.

  +-- Identified workholding and loose accessories

This is not a connection or disconnection diagram. It shows what to investigate and inventory.

Makino's discussion of wire EDM reliability describes the reservoir, filtration, deionisation and chiller functions within typical dielectric systems. Check the actual manufacturer's documentation for your machine's arrangement and fluid. Do not assume every EDM installation uses the same system.

If a unit serves more than one machine, mark it as shared. The sale proposal must explain whether it stays, transfers or needs a separately agreed arrangement.

For each item on the diagram, record identity, ownership, condition evidence and inclusion. “Complete system” is only helpful when the components behind that phrase are identified.

Include the following information where relevant:

• Main machine identity and documented work envelope.
• Work-tank and workholding arrangement.
• Generator and control configuration.
• Dielectric and filtration units, including separately located equipment.
• Wire-handling equipment and identified accessories.
• Manuals, service records and the agreed digital handover.
• Loose consumables, described by identity and known condition.

Do not promise a remaining filter life or a quantity of useful cutting hours from loose consumables. Packaging and stock records can help identify them, but they do not establish future performance.

A die-sinking machine needs a different package description. The spark-erosion guide explains the electrode and tooling questions that distinguish that sale.

A service invoice may show that a filter was changed. It may say nothing about the present condition of the chiller, wire threader or control. Keep the service questions attached to the component they concern.

Ask when the machine last ran, what faults were reported, which work was completed and what evidence records the result. If the machine has since been moved or stored, make that history visible. The incomplete service-history guide provides an evidence-gap log.

Keep brochure capability apart from observed condition. A demonstration, where properly arranged with competent people, should have a stated purpose and date. It should not become a guarantee of cutting accuracy on every material or workpiece.

The control may hold customer programs or machine-specific data. Identify the relevant files and permissions before promising them to the buyer. The software and backup guide separates those questions without prescribing deletion or recovery procedures.

Ask the removal contractor what they need to know about fluids, separate units, foundations and reinstatement. The foundations and anchoring enquiry helps define the building-related questions. Leave separation, fluid handling and packing methods to appropriately qualified people.

HSE's second-hand product guidance covers supply responsibilities in Great Britain. An itemised inventory does not, by itself, establish safe condition.

Send the diagram, inclusion list and known record gaps to UK Auction Group. That makes it possible to discuss the actual sale package rather than an isolated machine photograph.

The engineering and CNC guides cover the connected preparation topics.
