Selling a CNC machine: decide what the sale includes

A CNC machine sale starts with deciding what the buyer is being offered. The machine in the photograph might share a coolant unit, use tooling needed on another job, or run software licensed to the business. If those details remain unsettled, the price discussion starts with an incomplete description.
Write a sale-scope sheet before asking for a valuation. It does not need to be elaborate. It needs to show what goes, what stays and which questions still need an answer.
Walk around the asset boundary
Start with the machine's model and serial number. Then list the equipment connected to it and the loose items normally used with it. Include the items that are easy to overlook: a separate control pendant, spare chuck jaws, coolant equipment, a bar feeder or the cabinet containing machine-specific holders.
Presence is not proof of ownership. A customer's fixture, a service company's loan unit and a colleague's measuring tools may all be beside the machine. Check the relevant records before adding them to the sale.
For each item, choose an explicit status:
| Item | Proposed status | Evidence or action needed |
|---|---|---|
| CNC machine | Included | Match the serial number to the asset records |
| Dedicated coolant equipment | To confirm | Establish whether it serves another machine |
| Toolholder cabinet | Partly included | Identify the holders that production must retain |
| Customer fixture | Excluded pending permission | Confirm ownership and any written release |
| Control software | Transfer subject to confirmation | Ask the rights holder about the actual licence |
| Foundation and floor fixings | Separate removal scope | Obtain installation records and a contractor assessment |
This is an example of a scope sheet, not a suggested package for every CNC machine. A simple standalone machine will need fewer lines.
Give the valuer the same package you intend to sell
A valuation discussion is less useful if it concerns a bare machine and the eventual advert promises a fully equipped cell. Equally, do not send photographs of valuable accessories and assume that everyone understands they are excluded.
Describe the proposed package in writing. Mark unresolved items as unresolved. If you want to compare two options, name them clearly: machine with dedicated tooling, and machine with a smaller agreed starter set. The guide to selling CNC tooling together or separately explains how to make that comparison without breaking useful sets.
The Haas manual library illustrates why the machine's documentation and its option documents may need separate attention. It provides manuals for machines and supporting systems, with an archive for older material. Use the documents that match the actual equipment; a current brochure for a similar model is not enough.
Treat the digital handover as part of the package
The control may contain customer programs, setup information and business data. There may also be a separate programming computer, software licence or service account.
List these individually. Do not promise that buying the machine gives the buyer rights to every program or subscription associated with it. Establish what can transfer, what must remain private and who will manage the handover. Read the CNC software and backup guide before making commitments in a catalogue description.
Agree when possession can change
A sale date and a collection date answer different questions. The machine might be needed for a final production run. Its extraction could remain necessary until another machine leaves. A buyer also needs to know who arranges specialist work and which costs sit outside the purchase price.
Record the release date, viewing arrangements and outstanding contractor questions. For an installed machine, use the foundations and anchoring questions to identify what the building records and specialist survey must establish.
Condition and sale scope are separate matters. An accurately itemised package can still need safety work. HSE's guidance on second-hand work equipment explains the responsibilities attached to supply in Great Britain, including the limits of wording such as "sold as seen". Ask for competent advice where the sale basis is uncertain.
Once the package is clear, UK Auction Group can discuss the proposed sale with information that relates to the actual lot.
If selling a vertical machining centre, prepare a complete specification, or return to the engineering and CNC guides.
