The purpose of this trial is simply to perform a preliminary test demonstration for Lapping Job Shop to show the effectiveness of various cleaners in removing lapping oils.
For the various cleaners, cleaning will take place for five minutes at 110 F. All three parts will first be rinsed for one minute in a tap water bath set at 110 F. One of the parts will then be rinsed in a room temperature DI bath for 10 seconds. After rinsing the parts were then placed under the air knives for one minute and then blown dry with the heat gun.
After drying the parts were observed for lapping compound residue and spotting. One part was then cleaned in the Graymills spray unit. Cleaning temperature was set at 100 F and cleaning took place for two minutes. The part was then rinsed under warn, running tap water for a few seconds.
Trial Results:
All four cleaners were successful in quickly removing the lapping compound from the parts. No spotting was noticed on the parts, so a DI rinse may not be necessary.
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Conclusion:
Preliminary tests show that all four cleaners and both mechanical methods are possible cleaning methods for Lapping Job Shop. Future testing should be done with a variety of substrates and on parts that are more heavily contaminated.
