Eccentric bushing for fi ne adjustment
Regular fi ne boring heads have a threaded
spindle as an adjustment mechanism. In
this situation, spindle inaccuracy can cause
backlash and require extra effort during setup.
The ROTAFLEX eccentric bushing is easy to
use, and machining forces are transmitted
via a larger surface, ensuring a consistent
diameter during machining.
After rough adjustment of the insert
holder, the easy-to-read scale enables
fi ne adjustment to reach precisely the
diameter needed. Here, no parallax
errors occur when reading the scale.
