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

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)

Model

TL laser system

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

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