Parts and contaminants · 4 min readUltrasonic cleaning of CNC machined parts before assemblyA machined part that goes into an assembly carries its coolant, chips and burr flakes into the product unless they come off first. What assembly asks of the cleaning step, how to lay out wash, rinse and dry around the machining cell, and how to keep the part clean between the tank and the fitter's bench.

Parts and contaminants · 4 min readCleaning threaded parts and blind holes with ultrasoundTapped holes, blind bores and internal threads trap chips, coolant and air. Why the trapped air is the real enemy, how part orientation, degassing and movement get the liquid in, which frequency suits fine threads, and how to get the liquid out again.

Parts and contaminants · 4 min readCleaning hydraulic valves and manifold blocks with ultrasoundA hydraulic manifold is a block of intersecting drillings, and every one of them must be free of chips, burr flakes and coolant before oil touches it. The cleaning sequence after deburring, the cleanliness targets, the equipment for new blocks and for repaired valves, and how to keep the clean block clean until it is plugged.

Parts and contaminants · 5 min readRemoving machining swarf, chips and coolantTurned and milled parts carry cutting fluid and fine chips in every pocket, bore, thread and cross-drilling. Ultrasonic cleaning flushes them in one cycle. The bath, what milled parts need in particular, the filtration that makes it last, and the cleanliness checks a machine shop uses.

Industries · 3 min readUltrasonic cleaning in industrial manufacturingParts off the machining centre, the press, the grinder and the heat-treatment furnace, cleaned before inspection, coating, assembly or shipping. What a manufacturing shop asks of a cleaning tank, the cleanliness specifications that drive it, and the set-ups from a single ST tank to an MT multi-tank line.

Parts and contaminants · 4 min readCleaning engine blocks after machiningBoring, honing and decking leave chips, abrasive grit and honing oil in bores, galleries and blind holes, and one grain in an oil gallery can wipe a new bearing. How rebuilders and remanufacturers clean a machined block, with the tank sizes and loads that fit car and truck blocks.

Choosing a machine · 4 min readST or SF: when the bath needs its own filtrationThe ST series is a heated ultrasonic tank; the SF series is the same tank built around a circulation loop with a buffer tank, oil skimmer and laminar flow. The second costs more and stands longer between bath changes. Where the line between them runs, with the overlapping models compared.

Choosing a machine · 3 min readSpray washer or ultrasonic bathA rotating spray washer throws hot detergent at the part from nozzles as the basket turns; an ultrasonic bath immerses it. One is fast on big, open parts with gross soil; the other reaches inside. The SPR series, what it is good at, and the lines that use both.

Process and parameters · 4 min readFiltration and bath lifeA cleaning bath fails in three ways: it fills with particles, it saturates with oil, or its chemistry is used up. Filtration handles the first two and stretches the third. What a filtration loop and an oil skimmer do, when a bath needs them, and how to tell when a bath is finished.
