Trial Purpose:

To evaluate products form removal of machining fluid

Date Run:

02/17/2004

Experiment Procedure:

Seven cleaners were selected from the laboratory's database of past testing based on supplied data from client. Six aqueous based cleaners were diluted to 10% using DI water in 600 ml beakers. One semi-aqueous product was used at 50% diluted with DI water. An eight product was added as the client's current cleaner. All of the products were heated to 120 F on a hot plate.
Twenty-four preweighed aluminum coupons were coated with client supplied cutting fluid, Speedfam Vehicle 210 mixed with an abrasive. The oil and abrasive were first mixed in a bottle. The mixture was added to coupons using a swab and then heated for 10 minutes using a Master Appliance heat gun. The coupons were allowed to cool to room temperature before weighing a second time.
Three coupons were cleaned in each solution for 10 minutes using stir-bar agitation. Coupons were not rinsed but were dried using air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.

Trial Results:

Four of the eight products removed over 74% of the oil/abrasive mix within five minutes using no rinsing.  The Bio T 300 B removed over 97%.  Most of the coupons had an oil film remaining except the Bio T 300 B. The client's current cleaner, Bruilin 815 GD removed 68% of the oil. The following table lists the amount of soil added, the amount remaining after cleaning and the efficiency for each coupon cleaned.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The four effective products and the current cleaner will be tested under the same conditions except a water rinse will be added.
