The model name is a start.
The configuration is the machine.
Freeze the exact hardware, software, accessories, documentation and support entitlement included in the transaction.
Make every included item identifiable.
Machines with the same badge can differ materially by build date, control generation, spindle, table, probing, automation, software, transformer, chip handling and region. The purchase record must identify the delivered asset—not a generic catalog model.
Facts to establish
- Manufacturer, model, year or build date and serial number
- Control maker, control model, software generation and licensed functions
- Spindle, table, travels, axes, rotary units, pallet system and tool capacity
- Probing, tool measurement, through-spindle coolant, chip and mist systems
- Automation interfaces, robots, bar feeders, loaders and safety integration
- Manuals, parameters, backups, keys, passwords, media and transferable licenses
Documents and deliverables
- Serial plate and control-screen photographs
- OEM build sheet or option report when available
- Line-item quotation and included-accessory schedule
- Software and license transfer confirmation
- Packing and removed-component inventory
- Exception list for every represented feature not verified
Ask before the decision becomes expensive.
A useful answer identifies a person, document, number, date, scope or acceptance test. Replace assumptions with evidence.
What is physically installed?
Match the quote to plates, screens, cabinets, accessories and photographs. A brochure is not an inventory.
What remains licensed after transfer?
Confirm whether software, macros, subscriptions, postprocessors and remote services transfer to the buyer.
What ships separately?
List transformers, tanks, conveyors, rotary tables, fixtures, probes, manuals and loose tooling with identifiers.
Which revision governs?
Record quote revision, build sheet date and any approved change order so later substitutions are visible.
Pause when the scope is vague.
- A quotation that names only make and model
- Options described as included but absent from the written line items
- Unknown passwords, parameters, backups or license ownership
- Photographs from a different serial number
- Accessories promised verbally without an inventory or condition
What a controlled file contains.
- Identity sheet and serial evidence
- Configuration and option matrix
- Included and excluded property schedule
- Software and data-transfer record
- Photographic packing inventory

Machine ownership is a chain. Use the next relevant guide instead of treating any one checkpoint as the complete answer.

Machine Blue Book organizes research. It does not replace engineering, legal, tax, insurance, safety, appraisal or trade advice.
Is a model number enough to identify a CNC machine?
No. Serial number, build date, control, options, accessories and software determine the delivered configuration.
Why photograph the control screens?
Screens can document control identity, option pages, hours, alarms and installed functions, subject to later verification.
Should loose tooling be in the purchase agreement?
Yes, if it is part of the deal. Identify it in an attached schedule rather than relying on photographs alone.
Can software always transfer with a used machine?
No. License and subscription terms vary. Obtain written confirmation from the applicable provider.
