Friction testing machine

The Chase Friction Material Test Machine is
designed and engineered to evaluate the
frictional characteristics of materials used in
braking systems in accordance with the SAE
J661 test procedure. The machine may be
effectively utilized for quality control,
research and development, or certification
type applications, with highly repeatable
results.
The operation is based upon a one square inch
sample of material which is contoured to rub
against the interior or a simulated brake drum.
By controlling either the normal load or the
friction force while monitoring the other
parameter under various thermal, speed, and
load conditions, an assessment of the
materials frictional properties may be made.
Rubbing speed is controlled by a variable
speed drive, load is controlled by a closedloop
servo system, and the temperature of the
test drum is controlled by resistance heaters
and a forced-air cooling system.
