Working with a DSD12
3. Working with a DSD12
Application area:
The DSD 12 turning head is used for cylindrically stripping workpieces. The diameter
of the journal that has to be turned can be between ø 1.5 mm and ø 12 mm.
The DSD 12 can be used both stationary with rotating workpieces (e.g. on a turret in
a lathe) and as a rotating unit with stationary workpieces.
Operation:
The DSD 12 turning head is equipped with 3 cutting inserts, which are distributed
evenly around the circumference, which enables the workpiece to be centred opti-
mally. The toolpiece is positioned during the machining so that it is centred on the
workpiece and the working feed moves it in the 'Z' direction so that it is over the
workpiece. It is retracted in the 'Z' direction with the spindle still rotating after the
programmed turning length has been reached. Fast traverse can be used for the
retraction movement.
Fitting the cutting inserts:
The cutting inserts are fitted compactly in the cutting insert holders [100] and a coun-
tersunk screw [110] is used to secure them in place. A T7 Torx screwdriver must be
used to tighten up the screw.
Setting up the diameter:
The coarse adjustment is realised by offsetting the cutting insert holders in the serra-
tions. You must always ensure that all three holders are positioned in the same way
in the serrations. The serration pitch is 1 mm, i.e. if the holders are offset by one
serration then the turning ø setting will be changed by 2 mm.
Fine adjustment is realised centrally for all three cutting insert holders by using two
threaded pins [30]. Never over-tighten the three clamping screws [120] (max. 2 Nm).
The threaded pin marked with a '–' should be unscrewed until the diameter that is
approx. 0.5 – 1 mm bigger than the required turning diameter can be set up by
screwing in the threaded pin marked with a '+'. The '+' threaded pin should now be
screwed out slightly. The threaded pin marked with a '–' should now be screwed in so
that the cam ring [20] can be turned until the required setting is set up. One turn of
the threaded pin effects a diameter change of 0.08 mm.
A hardened bolt, whose diameter corresponds to the desired turning diameter, can
be used for a fast and precice adjustment of the turning diameter
The second threaded pin can now be screwed back in. The second threaded pin must
only be screwed in place lightly (approx. 3 Nm);
never over-tighten!
Now tighten up the clamping screws [120] (approx. 4 Nm).
