A useful vertical machining centre description separates three things: what the model was designed to do, what is fitted to this machine, and what someone has actually observed. Combining them into one confident paragraph is an easy way to overstate a used machine.
A brochure may describe an optional spindle. A service invoice may record a replacement component. Neither, by itself, tells a reader the complete present configuration. Build the description from evidence tied to the machine's serial number.
Start with identity, then specify the configuration
Record the manufacturer, full model designation and serial number exactly as shown. Photograph the plate where it is safely accessible. Keep the image alongside the written entry so another person can check a transcription.
Use the serial number when asking the manufacturer for information. Haas, for example, provides a parts search by machine model/year or serial number. That is a route to identifying relevant information, rather than proof that every part fitted today is original.
A working sale record could look like this:
| Detail | What to record | Where to check it |
|---|---|---|
| Machine identity | Full model and serial number | Plate and purchase records |
| Axis travel | Documented travel for this configuration | Matching manual or manufacturer confirmation |
| Table | Dimensions and documented load information | Model documents |
| Spindle | Installed specification and replacement history | Build record and service evidence |
| Tool changer | Fitted type and stated capacity | Machine documents and accessible identification |
| Control | Name, generation and relevant fitted options | Control records and option documents |
| Accessories | Included items listed separately | Physical inventory and ownership records |
| Condition | Known faults and dated observations | Inspection and maintenance records |
Leave blanks where evidence is missing. A blank marked "awaiting confirmation" is easier to resolve than an attractive but unsupported figure that has spread into several adverts.
Keep optional equipment out of the standard specification
Probing, rotary equipment, through-spindle coolant and different tool changers can materially alter the package a buyer is considering. List each supplied option. Note any uncertainty about its operating condition, licence or compatibility.
The Haas operator and service manual library separates machine manuals from documents for systems such as probing and coolant equipment. This is a useful reminder to search for the relevant option information, rather than assuming the main machine manual covers everything.
Do not copy a manufacturer's full options list into the advert. A reader may reasonably take that list to mean the options are fitted and included.
Describe use without turning the counter into a verdict
Record counter labels as displayed, with a photograph and a date. "Hours" on its own is too vague. The guide to spindle hours and power-on hours explains why the label and known counter history belong beside the number.
Service evidence needs similar care. "Regularly serviced" is difficult to assess without dates or records. A short statement identifying the available invoices and the last recorded work is more useful. If the file is incomplete, follow the missing service history guide instead of trying to fill the gap with reassurance.
Avoid claiming that travel, spindle speed or age proves machining accuracy. If performance evidence exists, describe what was measured, by whom and under which conditions. Otherwise, keep the description to supported facts.
Make the photographs match the written lot
A photo of a rotary table is misleading if the table is being retained. A general workshop shot can also make a separate extractor or tooling cabinet look included.
Use the CNC photograph checklist to capture the plate, control and offered equipment. Add captions where inclusion could be unclear. Take photographs through safe access arrangements; a sale catalogue is not a reason to remove guards or start an unfamiliar machine.
Before sending the information out, compare the title, specification table, photographs and inclusion list. They should all describe the same machine package.
