Pneumatic Connection

Connect the FDB-AC 180 as shown in the figure.
A special Speedeburr adapter is available as extra equipment, to
enable standard air nipples to be coupled to the Straight FDB-AC.
Air silencers can be coupled to the exhaust ports of the adapter, to
take away the noise when exhaust air enters the atmosphere. The
drive air to the vane motor should be mist lubricated by use of
conventional pneumatic equipment.
An external pressure control valve, for example mounted on the
industrial robot’s upper arm, will control the axial force on the
rotary tungsten carbide file.
The axial force is adjusted until a chamfer with the correct width is
produced, for a given path speed.

NOTE

Poor performance will result if the correct components are not
used.
Pneumatic components used for the motor drive circuit must be
able to meet the air consumption requirements
