Steady and follow rest
Steady and follow rest compensate for the deflection of long shafts caused by resultant
cutting forces. The roller jaws of the rests prevent the pieces to be turned form deflection.
They are to be adjusted in such a manner that the turning axis of the workpiece is in true alignment
with the height of the centres of the machine. At the point of support, the pieces to be turned must
be completely round.
Steady rest:
The steady rest can be firmly clamped to any
position on the slide bars. It is put on the slide
bars with its half shells and fixed to the slide bars
by means of the clamping plate.
Follow rest:
The follow rest is used particularly for turning thin,
long shafts and for turning threaded spindles. It is
screwed firmly on to the threaded drilled holes of
the compound rest provided for this purpose, so
that it holds the workpiece as near as possible to
the turning tool.

Square turret head
The square turret head is used instead of the clamping plate in order to clamp the tools.
Four turning tools can be changed simultaneously. By swivelling the turret head by 90 degrees
each time, the required turning tool can quickly be brought into its working position
There are four centering holes on the bottom for
securing the square turret head in its four
positions. For this purpose, the screw supplied
with the springmounted steel ball must first be
screwed into the threaded hole in the upper part
of the turning carriage.
