TS 750 and TS 150
Workpiece touch probe

HEIDENHAIN has been developing andmanufacturing touch probes for workpieceand tool measurement on machine tools
for over 35 years now, setting standards
with wear-free optical sensors, for example.

The TS 750 is equipped with high-precisionpressure sensors. The trigger pulse is
obtained through force analysis. The forcesthat arise during probing are processed
electronically. This method delivers extremely
homogeneous probing accuracy over 360°.

With the TS 750, the deflection of thestylus is measured by multiple pressure
sensors that are arranged in the stylus
holder.
The probing forces arise immediately upon
the first probing contact (see figure 1: 2).
The signals generated by the sensors areprocessed, and a trigger signal is generated.
The relatively low probing forces involved
provide high probing accuracy andrepeatability, virtually without any effect on
the measured object. The deflection forcesof the springs only come into play during
further deflection until the machine stops
moving (see figure 1: 3).
