The useful question when selling a manual mill is often “What goes with it?” A vice may be staying for another machine. The collets may belong to several different spindle systems. A dividing head may be complete apart from the parts that make it worth including.

Settle those details before calling the lot a milling machine “with tooling”. That phrase is easy to write and difficult for a buyer to price.

Describe the mill before allocating its attachments

Identify the make, full model, serial number and actual arrangement. Do not treat a turret mill, a universal mill and a CNC machining centre as interchangeable descriptions. Record the configuration supported by the manufacturer's documents, including any separate head or arbor equipment.

Table size and axis travel belong on different lines. XYZ's manual milling-machine range lists them separately: the surface available for workholding is not the same measurement as the machine's movement. Obtain the figures for the particular machine being sold, including relevant vertical or quill movement where documented.

Also record the spindle interface, speed arrangement, fitted power feeds and digital readout. Name the readout and its axes rather than allowing “DRO fitted” to imply that every axis has been checked. A display lighting up is one observation; correct operation is a different claim.

Allocate each attachment once

Use a sheet like this before the photographer arrives. The examples show decisions to make, not a standard package every mill should include.

Item Identification to obtain Allocation decision
Machine vice Make, type, visible identity and associated base Included with this mill or retained for another machine
Collets and holders Markings, interface and complete set contents Include only identified compatible items
Dividing head Head identity, plates and associated components Keep supported set together; name missing parts
Tailstock for dividing equipment Identity and documented association Do not assume a nearby item is the matching one
Power feed Fitted axis, manufacturer and known condition Distinguish installed feed from loose spare unit
Horizontal arbor equipment Arbor, support and relevant identification Confirm association with this machine
Rotary equipment Model, interface and included controls Establish compatibility separately

Give unidentified items a holding category while you investigate them. That is better than putting every loose holder in the cabinet into the lot.

The collets and toolholders guide explains how to organise mixed tooling. For a rotary unit, use the rotary-table guide before claiming it is compatible with the mill.

Deal with shared equipment before the sale date

Ask the people using the workshop which attachments are dedicated and which move between machines. A vice currently sitting on the table may still be needed elsewhere. Record the answer against the item, with the person who confirmed it and any release date.

In a toolroom clearance, compare the inventories side by side. If the same dividing head appears against two machines, the lotting plan needs a decision. If the workshop has already closed and power is unavailable, the guide to undemonstrated machines covers the resulting evidence gaps.

Where a buyer might reasonably expect an accessory shown in a photograph, name the exclusion in the description. Avoid relying on a general note hidden elsewhere in the catalogue.

Keep condition statements proportionate

Photograph accessible table surfaces, visible damage and the installed attachments. Preserve service reports and known fault notes. Do not translate a clean table or a smooth-looking video into an accuracy claim.

HSE's inspection guidance explains that inspection requirements depend on equipment and risk. Sale photographs are an inventory aid; they are not a safety inspection. An unresolved concern about guarding, controls or other safety matters needs competent advice before the supply basis is settled.

For an older neighbouring lathe, follow the manual lathe guide rather than recycling the mill's specification headings. Each machine needs the dimensions and accessories that matter to its buyer.

Once the mill and attachments have a consistent inventory, send it to UK Auction Group. Explain which equipment is dedicated, which remains shared and which details need clarification. That gives the sale discussion a usable starting point.
