MACHINING AND GRINDING
QUAKERCOOL?7101 AFH
THE SOLUTION
Quaker introduced QUA KERCOOL?7101 AFH in one hydraulic head line, requiring 600 liters of coolant. After
a trial period of six months, Quaker was able to show ?on an annualized basis ?over 38% savings in oil cost.
In addition, operators recognized a positive improvement in machine cleanliness, and noted that there was no
compromise in tool or sump life.
CHALLENGES
A leading supplier of CRDI fuel
injection pumps to automotive
OEMs in India was looking to:
换 Reduce coolant consumption
in precision machining of
steel materials
换 Improve machine cleanliness
and corrosion

Consumption/Cost Savings Per Machine
Oil cost (loading) per month 8%
Oil cost (top up) per month 25%
Total cost savings (annualized) 38%
Due to the savings demonstrated in one machine, the
manufacturer decided to switch to Quaker抯 coolant
for several more machines in the facility.
THE PRODUCT
QUA KERCOOL?7101 AFH is an advanced esterbased,
bacteriostatic, semi-synthetic fluid with a high
mineral oil content. Developed for a multi-purpose
action in machining and grinding, where surface
finish is a major requirement. QUA KERCOOL?7101
AFH is well suited to traditional as well as heavy-duty
machining operations on cast-iron, steel and
alloy steels.
THE EXPERTISE
Metalworking lubricants represent a very minor part
of the costs in a metalworking process, typically
less than 1%. This case illustrates the importance
of correct fluid selection. The impact of the fluid
can be a multiple of its costs, making the price
of a metalworking fluid insignificant. That is why
Quaker focuses on developing fluids with the highest
performance without compromise, fluids that sharpen
your competitive edge.
