Washing and Deburring Technology

This patented nozzle is the ultimate all-in-one cleaning tool. Equipped with a PLC-controlled spray pattern, it excels at general washing and high-pressure deburring. A pulse feature intermittently interrupts water flow, delivering a rapid, repeated impact that effectively removed metal burrs and chips, without the need to increase water pressure.

Ideal for cleaning complex internal cavities and for heavy chip removal, the immersion flood wash consists of a rinse halo, solution tank, fast-fill nozzles, and quick-drain valve. An industrial robot immerses the part into the filled solution tank and shakes it back and forth under water, agitating it to clean every surface. The solution tank quickly drains, helping to evacuate chips and debris before the robot removes the part, passing it through the rinse halo.

Six high-pressure nozzles rotate at high speed and cover a wider surface area than the Water Hammer® nozzle, making this an ideal solution for cleaning parts with large surface areas.

This long, narrow nozzle uses high pressure to clean internal part cavities accessible through holes at least 6 mm in diameter. An industrial robot aligns the part and lowers it over the probe for cleaning.

Independent from the primary wash process, this secondary rinse cycle uses a dedicated solution tank and filtration system to ensure complete removal of particles over 600 microns in size.

Drying Technology

High-volume blower air (25 HP, 150 mbar, 900 CFM) is blown through teardrop-shaped air knives, producing a thin curtain of high-velocity air to remove excess water from parts without physical contact. This unit includes variable frequency drive (VFD) speed control.

The vacuum dry is a secondary drying process, typically following a primary air knife blow-off process.

After loading the clean part, the vacuum bell chamber closes, creating a sealed environment. A vacuum pump reduces the pressure inside the bell chamber, vaporizing moisture from part surfaces, internal cavities, and blind holes, ensuring absolute part dryness.

Part temperature can increase during the washing and drying process. The cooling tunnel uses a chilled-water heat exchanger and recirculated air to cool clean parts after they exit the washer. Sensors calculate ambient and part temperatures to cool the part ahead of downstream operations. An enclosure helps reduce the risk of recontamination.

Environmental Technology

During the cleaning cycle, waste materials, including chips, oil, and cutting fluids, are removed from the processed parts. Mesh-based filters remove solid waste, leaving oil waste for separate filtration.

The HydroSkim™ Oil Separator operates based on the principle that oil is lighter than water and accumulates at the surface of the main tank.

This system consists of a waste oil intake system and an oil waste removal system that uses a decanting process for separation.

The waste oil intake skimmer floats near the top of the water surface in the main tank collecting the oil/water mixture. It pumps it to the oil waste removal system, where the oil is further separated from the water and discarded from the process.

The mist collector + vapor condenser improves plant air quality and reduces water consumption. It captures up to 75% of the humidity from the process house and recycles it back to the wash tank. At the same time, a filter removes small particulates and aerosols from the exhaust stream.

In the first step of the filtration process, the media filter removes particles over 50 microns in size. A transfer pump moves the process water to the media filter, where it is drained through a partially-submerged, mesh-covered drum. A chain-driven scraper removes the particles and empties them into a chip cart for disposal as it rotates.

Secondary filtration is provided by the self-cleaning automatic back-flush filter, which removes particles over 30 microns in size.

These filter vessels provide the final filtration of particles 10 microns in size or larger. Filter cleanliness is monitored using pressure differential sensors, and filter change requirements are communicated through the HMI or MES.
