1. 3D-Touch Probe mounting and radial run-out checking
1.1 Clamp 3D-Touch Probe in suitable chuck and position into machine spindle.
Check that stylus is firmly seated, and then check radial run-out at stylus (stylus ball)
(cf point 3.2 Change of stylus). Adjust if necessary (cf point 4 Adjustment of radial
run-out).
1.2 Align the dial "zero" position with the pointer via the setting screws when calibra-
ting the measuring path. The measuring accuracy of the 3D-Touch Probe 2007 can be
inspected with the end measure.
1.3 Determine effective total length of 3D-Touch Probe (TL) (cf fig. 2):
TL = effective total length of 3D-Touch Probe after finishing calipering process
(indicator needle in "zero" position):
In "zero" position the length of 3D-Touch Probe is shorter by the advance V = 2.00 mm.
The value (V) for the advance compensation ist identical for all styluses.
Effective length of 3D-Touch Probe (TL) = total length (L) – advance (V = 2.00 mm)
– Preset effective length of 3D-Touch Probe TL as a tool length in the tool memory
of the machine tool control (eg under T 99)
– Call up tool: 3D-Touch Probe (eg T 99)
2. Calipering of workpiece
– Machine spindle must be stopped and coolant supply must be switched off.
– Approach surface / workpiece edge at a right angle (cf fig. 3).
When approaching the workpiece, the stylus ball must not be passed along
the workpiece edge (wrong results). Place the device within the visual range
of the operator prior to starting the calipering process. The 3D-Touch Probe
must not be turned during the process. Should the device be accidentally turned,
the entire process must be repeated.
2.1 Radial and axial approach:
– Watch scale of the 3D-Touch Probe dial.
– After stylus ball has contacted the workpiece surface, indicator needle moves
towards "zero".
– While using the standard stylus, the exact difference value can be directly read on
the scale.
– Calipering process is finished when "zero" position has been reached.
Note: If the zero position is overrun the whole procedure must be repeated.
– Machine tool spindle axis = workpiece surface

3. Styluses
– The 3D-Touch Probe 2007 is equipped with one standard stylus
(order no. 107323) on delivery.

3.1 Predetermined breaking point of stylus
– In order to protect both workpiece and the 3D-Touch Probe mechanism all styluses
have got a predetermined breaking point (ceramic shaft).
3.2 Changing the stylus
– To loosen a stylus insert an
allen key into bore hole (cf fig.).
– Screw a new stylus into
the mounting hole, place an allen
key into bore hole
and tighten (cf fig.).
– Check the roundness.
3.3 When changing a stylus
(cf point 3.2) the tool length TL
must be newly determined
and entered once again in the
machine control unit !
