NOTICE
All pneumatic fittings and tubing must be capable of withstand-
ing the repetitive motions of the application without failing. The
routing of pneumatic lines must minimize the possibility of over
stressing, pullout, or kinking the lines.
Failure to do so can cause some critical pneumatic lines not to
function properly and may result in damage to equipment.
The air supply should be dry, filtered, and free of oil. A coalescing
filter with elements rated for 5 micron or better is required.
A high-flow air pressure control regulator is required to supply the
spindle motor . A second, precision, self-relieving regulator will
supply air for the compliance or centering force.
The compliance force is applied radially and is adjusted until the
desired cut is made. The robot traversing speed will also be ad-
justed to achieve the desired finish.
NOTICE
Pneumatic components used for the motor drive circuit must be
capable of meeting the air consumption requirements
Poor performance will result if the correct components are not used.
Conventional, customer-supplied, pneumatic components are used
to control the air supply to the deburring tool. SCHUNK recommends
that the user install a high-flow pneumatic pressure regulator and a
high-flow valve to properly supply a stable air supply to the spindle
for the maximum flow requirement. The FDB
will not operate properly if supplied air is below 6.2 bar.
A second, precision, self-relieving regulator is used to supply the
compliance (centering) mechanism. This pressure corresponds to
the side force on the rotary burr. Very little airflow is required for
the compliance mechanism.
If the complete workpiece can be deburred with equal force, a
conventional, manual pressure regulator can be used for compli-
ance. If the burrs to be removed vary from place to place on the
work piece, and this variation is repeatable for all work pieces of
the same type, it may be necessary to adjust the force using an
analog pressure regulator controlled from the robot. An analog
output port in the robot or logic controller will be needed.
Solenoid valves are actuated from the robot or program logic con-
troller by means of a digital output signal.
