7.2 FDB-AC 180
The Compensation piston is an important part of the Straight FDB-
AC. The Compensation piston is pushed forward into contact with
the burr edge by use of a remotely controlled air pressure.
The air vane motor is decoupled from the linear movement of the
Compensation piston, to reduce inertia and increase the stability
of the contact force when deburring. The spline coupling transmits
torque to the rotary file.
Ball bearings ensure an even running of the tungsten carbide file.
A very little friction torque is transmitted through the ball bearings
to the Compensation piston cylinder, which rotates slowly inside
the stationary outer cylinder. Thus stick- slip or static friction of
the Compensation piston is avoided. The Compensation piston
cylinder is in addition precision ground to ensure very little friction
in the axial direction.
