Machine shops often need to wash parts that come out of machining centers with true oils (petroleum based) as well as water soluble coolants. In this application, the customer had a long list of true oils they needed to remove from precision machined parts.
Oil contaminants include:
- Mobil DTE Oil Heavy 100 ISO VG 100 Machine Oil
- Mobil DTE Oil Light 32 ISO VG 32 Machine Oil
- Mobil DTE Oil Light 24 ISO VG 32 Machine Oil
- Redline R022
- Koolrite 2290 Metal Working Fluid Coolant
- Lubetech Waylube 68 Oil
- HIT COOL 19055
- BC623 Antirust
- Star 165
While many shops start with a simple drum mounted solvent parts washer equipment, they quickly outgrow the size, capabilities, etc and the solvent is highly flammable and costs become expensive. They also face becoming a hazardous waste generator.
Cleaning both true oil and water based coolants is where aqueous water based parts washer equipment often excel.
The Ultrasonic Wash, Rinse, Dry Parts Washer With Oil Removal System
The agitated immersion ultrasonic parts washer equipment with an oil removal system allows for the cleaning challenges listed above to be cleaned with ease. Solvent parts washers utilize the proper alkaline based cleaning chemistry, typically mild detergents. This means that both true oil and water coolants can be cleaned and removed from stainless steel, tool steels, aluminum, brass and numerous other alloys.

The ultrasonic solvent cleaner allows for the uniform cleaning of inside and outside the part that solvent based parts washer users have come to expect from the lower surface tension characteristics of solvent. The ultrasonic energy creates a micro-scrubbing action and (alternating ultrasonic then agitation) agitated immersion oscillating platform in combination with the spray under immersion high flow pump flushes and filters particulate and soils away from the part.
True oil based machined parts are easily cleaned with the designed oil removal system to constantly sweep/sparge overflow floating oils on the surface of the tank into a quiet tank where the oils can settle out and be skimmed and removed from the solution without concerns with redepositing on parts.
After parts are cleaned, they need to be properly rinsed with as pure of water as possible (RO or DI water suggested). This is accomplished by a second stage parts rinsing tank that has slowly overflowing rinse water to ensure the rinse water stays clean from any dragout introduced from the wash stage.
A heated air knife dryer (digitally temperature controlled ) drys and removes the rinse water from the parts to leave a spot free finish. No matter how parts are manufactured: CNC miled, wire EDM, swiss machine, lathe, laser cut, water jet, you name it, they can be washed and cleaned in this water based ultrasonic solvent cleaner.
