Heidenhain Tool Touch Probes

Tool measurement on the machine shortens non-productive times, increases machining accuracy and reduces scrapping and reworking of machined parts.

With the tactile TT touch probes and the contact-free TL laser systems, HEIDENHAIN offers two completely different possibilities for tool measurement. With their rugged design and high degree of protection, these tool touch probes can be installed directly within the machine tool’s work envelope. Tool measurement is possible at any time: before machining, between two machining steps, or after machining is  done.

Touch Probe Systems

The TT 140 and TT 449 are 3-D touch trigger probes for tool measurement and inspection. The disk-shaped probe contact of the TT is deflected during physical
probing of a tool.

At that moment the TT generates a trigger signal that is transmitted to the control, where it is processed further. The trigger signal is generated through a wear-free optical switch that ensures high reliability.

TT 140
• Signal transmission to the NC over
connecting cable

TT 449
• Signal transmission over infrared beam to transmitter/receiver unit
• The SE 642 is a common transmitter/receiver unit for tool and workpiece touch probes with infrared transmission
