1. State the soil, its age, and its source
Cutting oil, cutting fluid, and grinding residue are not one substance, and the residue on a machine base is not the same as the residue on a machined part. Write down: whether the soil is neat oil, an emulsion, or a dried and reheated film; whether it has been on the surface hours or weeks; and what generates it (coolant carry-off, way-oil splash, hand contact, chips packed with fluid). A dried, heat-aged film behaves differently under cleaning than fresh oil, and this single sentence changes the recommended mode, the pass count, and the time per machine.
Also state what must stay untouched: ways, guide rails, ball screws, linear encoders, electrical cabinets, and sealed bearings are cleaned under different rules than the machine exterior and the enclosure panels. If parts are to be cleaned as well as the machine body, that is a separate requirement and should be listed separately.
2. Record the cleaning environment
The supplier cannot size a machine without the conditions around it:
- Power on site: supply voltage available at the cleaning point, and whether a temporary connection is acceptable.
- Water supply: whether a water inlet is available at the point of use, and the fitting type.
- Drainage and runoff: where the oil-water mixture goes, and whether the floor layout allows it to be collected.
- Access: aisle width, door height, floor load, and whether the machine must be cleaned in place or can be moved to a bay.
- Temperature and humidity of the area, and whether other production is running alongside the cleaning.
A fixed installation and a mobile machine are different answers to these constraints, so include an area sketch or a photograph of the machine position with the aisle dimension marked.
3. Define the mode you expect, not the pressure you assume
In machine-shop cleaning, the useful question is whether the job needs dry steam, wet steam, or hot water. Dry steam works at high temperature with comparatively little free water, which matters around electrical components, way covers, and areas where standing water would reach joints. Hot-water and wet-steam modes carry more water and do the flushing step once the oil has been loosened. Ask for a machine tool steam cleaning configuration that supports both stages, and state which areas may receive water and which may not. For the figures that matter — heating power, supply voltage, tank volume, footprint — read the model page rather than a general description; for example the fixed steam cleaning machine page in the PowerDe cleaning series lists its published parameters, while steam temperature and pressure are not published for every model and should be confirmed with the manufacturer before they are written into a specification.
4. Set the trial scope and the acceptance criteria
Write the acceptance test into the enquiry, so both sides measure the same thing. A defensible trial scope is two machines, or two halves of one machine, cleaned to the same routine. The criteria to name in the brief:
- Residue condition after cleaning, judged on defined surfaces: enclosure panel, chip conveyor area, machine base, and one area near a seal.
- Time per machine, including setup, hose handling, and cleanup after the pass.
- Whether the machine can return to production immediately, or whether drying time is required.
- Whether chemical degreaser is still needed, and at what quantity.
- Operator number and the effort involved, recorded by the team doing the work, not the person writing the brief.
A cutting oil removal equipment trial that measures only appearance will be argued over at the budget meeting. One that measures time, water, chemical use, and return-to-service can be approved.
5. Ask the supplier for what you should receive
State the deliverables you expect with the quotation, so proposals can be compared line by line: the configuration and options in writing; published parameters for the exact model offered; the accessory set and what each nozzle or lance is intended for; the consumables list; spare-part availability and lead time; the warranty terms and what voids them; operator training, and in what language; the service and repair route for your region. If your factory has several machine types or a cleaning routine that has to run inside a fixed window, say so and ask whether the requirement calls for a customized steam cleaning equipment build rather than a standard model.
Putting the brief together
One page is enough: soil description and age; what may not be wetted; the environment (power, water, drainage, access); the mode you expect and why; the trial scope with the criteria above; and the deliverables you expect with the price. This structure turns the enquiry from a product question into a solvable specification, and it gives the manufacturer enough to say no to the wrong model before it is quoted. Send that page to the supplier's engineering contact rather than to a general sales address, and ask for written answers to each numbered point.
