The flexible FDB tool from
Schunk is said to compensate
for deviations between robot
path and the workpiece contour to
provide the desired results on the
workpiece, while reducing tooling
costs and shortening programming
and commissioning times.

The high-speed compressed air
tool is suitable for chamfering
complex geometry workpieces made
from aluminum, plastic, steel and a
number of additional materials. The
FDB system imitates manual
chamfering with precision by using
an adaptive spindle and motor
system that is flexibly seated on a
self-aligning bearing.

Several small pneumatic pistons
enable the spindle to deflect by up to
9mm, so the air motor can move in
direction of the housing. This radial
scope compensates for deviations
between the tool path and the workpiece
contour. The flexible spindle
clings to the workpiece. Even with
irregularly-shaped components, a
uniform result can be achieved. The
programmer has less fixing points to
input for the robot path, so time for
programming is said to be reduced.
