Application
The tool breakage detector can bepositioned in the work envelope suchthat it is easily accessible during toolchanges at rapid traverse. The inductive
sensor can detect tools as they pass by
while they are spinning at their operational
speed, or at least at 1000 rpm. Thanks toits rapid scanning technology, even verysmall tools made of HSS steel or carbide
are detected. For use on all controls, thebreakage sensor generates a floating
trigger signal and an HTL switching signal.
The control can evaluate these signals via
standardized instruction sets. In addition,
an LED indicates whether a tool has beendetected. As a result, machines already inuse can benefit from automated breakage
detection as well.
Advantages• Non-cutting time for breakage inspection
is reduced by up to six seconds.
• The wear-free TD 110 is unaffected bycoolant and contamination.
• Tools do not need to be cleaned forreliable tool inspection.
• Reduction of system costs and carbon
emissions due to not needed purge air(unlike laser systems).

Connecting to TNC controls
The tool breakage detector can beconnected via the cables for the TT 160
touch probe to the touch probe input X112/X113 of the PLB, UEC or UMC, and to X12/
X13 of the iTNC 530.
Our Service team provides optimal support
for the operation of HEIDENHAIN controls,including cycles for breakage detection thatcan be added via TNCremo. Please contact
the HEIDENHAIN Service team:Remote support
service.nc-pgm@heidenhain.de
ID 1369787-35
Requirements for retrofitting:• TNC option: Touch Probe Functions• Touch probe for setting up the TD 110

Connection to other CNC controls
The HTL switching signals and the floating
outputs can be used for connection to thePLC or to other IO connections of nearly
every CNC control (assistance from themachine manufacturer may be necessary).
For information about programming cycles,
refer to the TD 110 documentation.
Fast and versatile mounting
Installing the tool breakage detector at
the tool change position enables very fastchanging times and maximum reduction in
non-cutting time. The different detection
paths permit various possibilities for
installing the TD 110 in the work envelope.
In the simplest case, the TD 110 is mounted
at the edge of the machine table.

Detection
Horizontal mounting

Vertical mounting

If the tool radius (for example, of a drill)
is not available in the control's tool table,
then the TD 110 can be mounted vertically.

The drill points and corner radii areaccounted for via a linear offset, andthe tool radius is taken into accountby the cycle.

Passing by
The tool passes by the tool breakage
detector from the side (three-axis motion).
Very short cycle times are possible.

Supported tools

Passing byType

Plunging
The tool plunges into the sensor’s range
from above (two-axis motion). This scenario
is especially advantageous if the TD 110 ismounted on the same portal as thespindle.

Approaching
The sensor surface of the TD 110 isapproached from the front up to theoperating distance (two-axis motion).
The tool can then be moved away ina vertical upward motion.

Plunging

The machine manufacturer can also adapt
the tool inspection cycle to other mounting
situations while still supporting the sametools. Standardized instruction sets areused to evaluate the switch signal.
