The top seven products were selected from the previous lab trial. Each product was diluted to 5% using DI water in 600 ml glass beakers. Solutions were heated to 130 F on immersed in a heat bath in a Branson 40 kHz ultrasonic tank. Products were degassed for five minutes.
Twenty-one preweighed steel coupons were coated with the Tru-Edge Cutting Fluid using a swab. Coupons were weighed a second time to determine the amount of soil added. Three coupons were immersed into each product and cleaned for 5 minutes using ultrasonic agitation. Following cleaning, coupons were rinsed for 15 seconds in tap water at 120 F and dried using air blow off for 30 seconds at room temperature. Final weights were recorded, and efficiencies were calculated.
Six of the seven products removed more than 90% of the cutting fluid using ultrasonic cleaning for five minutes. Five of these removed over 99%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
