Minimal Quantity Lubrication Units
Very small, precisely metered doses of oil delivered to a cutting, forming or sliding contact, usually carried by an air stream to the nozzle. The quantity is chosen so the oil is consumed at the contact and the workpiece and swarf come away essentially dry. SES holds the range as an authorised SKF distributor, covering dose range Fractions of a millilitre per stroke, adjustable per outlet; outlets Single nozzle up to multi-outlet manifolds; air supply Clean dry compressed air, regulated at the unit; reservoir Small transparent tanks with level switch. Executions include single-outlet spray units, multi-outlet manifold units, coaxial internal-feed nozzle systems, roll and strip surface application units, among others. It is specified most often into band and circular sawing of billet and structural section and press shop blanking, piercing and deep drawing. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Minimal Quantity Lubrication Units in the parts of a plant where this particular duty actually occurs. In practice that means band and circular sawing of billet and structural section, press shop blanking, piercing and deep drawing, roll forming and tube mill lines, and equally furnace and oven conveyor chains where oil must not drip, cut-off saws and profile cutting in fabrication shops. What links them is the duty rather than the machine name — dose size: Millilitres per hour, not litres per minute. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Swarf leaving the machine visibly wet — A reduction in dose and a check on nozzle aim before you change the oil. Excess in minimal quantity work is not a safety margin, it is oil that must be cleaned off the part later. Saw blade tips burning while the rest of the cut is clean — Nozzles on both sides of the blade aimed at the tooth entry point. Delivering to the exit side lubricates the swarf and leaves the cutting edge to dry. Parts that go straight to welding or painting — An oil formulated to evaporate or be weld-through compatible, confirmed on scrap first. Lubricity alone is the wrong selection criterion when the residue causes porosity downstream. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Start with the smallest dose that keeps the tool cool and work upward, one increment per shift. Commissioning at a generous setting and reducing later never happens, because nobody wants to be the one who turned the oil down.
