Tool measurement

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.

	TT touch probes
Model	TT 160	TT 460
Probing method	Physical probing
Probing directions	3-dimensional: ±X, ±Y, +Z
Probing forces	Axial: 8 N, radial 1 N
Tool materials	Breakage-prone teeth are at risk
Sensitivity to unclean tools	Very small
Possible measuring cycles	Length, radius, breakage, individual teeth
Installation effort	Simple connection to NC control
Signal transmission	Cable	Radio/infrared to SE 660; infrared to SE 642
Repeatability	2 σ ≤ 1 µm
Min. tool diameter	3 mm ¹⁾

Measuring the tool radius

By probing the rotating tool, the touch probe finds the maximum tool radius. Then the tool orients itself to the longest tooth. The exact radius is measured by repeatedly probing the longest tooth to "close in" on the highest value

Individual tooth measurement is possible only with your HEIDENHAIN control.

	TL laser system
Model	TL Nano	TL Micro 150	TL Micro 200	TL Micro 300
Probing method	Non-contacting by laser beam
Probing directions	2-dimensional: ±X (or ±Y), +Z
Probing forces	No forces, operates without contact
Tool materials	Any
Sensitivity to unclean tools	High (tool must be cleaned with blown air before measurement)
Possible measuring cycles	Length, radius, breakage, individual teeth, tooth geometry (also for combined contours)
Installation effort	PLC adaptation in the NC control necessary (6 outputs, 3 inputs), compressed air connection
Signal transmission	Cable
Repeatability	2 σ ≤ 0.2 µm		2 σ ≤ 1 µm
Min. tool diameter	0.03 mm		0.1 mm
Max. tool diameter	37 mm ²⁾	30 mm ²⁾	80 mm²⁾	180 mm ²⁾

1) Probing force must not result in tool damage
2) With centered measurement
