The customer’s expectations have been exceeded. Hocut 8640 performs exceptionally in terms of lubricity and chip removal; along with lowered usage, waste, labor, and downtime, and with more consistent concentration control. The greatest benefit has been the elimination of additives; not only are they costly and labor?intensive, but also indicative of inconsistent coolant chemistry that can lead to additional parts inspection, as well as staining and rework.
Concentration and Special Controls. Required concentration is lower at 9-12% compared to previous vegetable-based (10-15%) and semi-synthetic (15-22%) coolants. Machine tool speed and feed rates required no adjustment.
Value-Added Information for Cost Justification. Reduction in coolant spend; elimination of additives spend. Reduction in labor related to coolant and additive adds. Reduction in waste, labor and downtime related to sump cleaning.
