Measurement of milling cutters
– Measuring length, radius and wear directly in the machine
The tool is of course a decisive factor in
ensuring a consistently high level of pro-
duction quality. This means that an exact
measurement of the tool dimensions and
periodic inspection of the tool for wear and
breakage, as well as the shape of each
tooth, are necessary. HEIDENHAIN offers
the TT trigger tool touch probes as well as
the non-contacting TL Nano and TL Micro
laser systems for tool measurement.
The systems are installed directly in the
machine’s workspace, where they permit
tool measurement either before machining
or during interruptions.
More information about workpiece touch
probes is available on the Internet at
www.heidenhain.de or in the Touch
Probes brochure.
The TT tool touch probes measure the
tool length and radius. When probing the
tool, either while rotating or at standstill
(such as for measuring individual teeth),
the contact plate is defl ected and a trigger
signal is transmitted to the TNC 640.
The TT 140 uses signal transmission by
cable, whereas the TT 449 operates with
signal transmission over infrared beam and
does not require a cable. It is therefore
particularly suitable for use on rotary and
tilting tables.
The TL Nano and TL Micro laser systems
are available for various maximum tool
diameters. Using a laser beam, they probe
the tool without contact, and can detect
form deviations of individual teeth along
with the tool length and radius.
