Probes

Traductori


Probes manufactured by Renishaw can be classified into two main categories: touch-trigger (TP20 si TP200) and analogues used in continuous scanning (SP-25,SP-600,SP-80)

TP20

Probe-TP20

Probe-TP20

Probe-TP20


The TP20 is a compact 5-way, or 6-way, kinematic touch-trigger probe system. The two-piece design, comprising probe body and detachable stylus module(s), connected using a highly repeatable magnetic kinematic coupling. This provides the facility to change stylus configurations either manually or automatically without the need for requalification of the stylus tips, thereby giving significant time savings in inspection routines.

Modules offering a range of trigger forces allow the probe performance to be best matched to the measurement task. A set of probe extensions is also available, as is a 6-way module. The stylus mounting thread accepts styli from the Renishaw M2 range.
The TP20 system is easily retrofitted and is compatible with existing touch trigger probe interfaces, extensions and adaptors.

TP200

Traductor-TP200

Traductor-TP200

Traductor-TP200

  • Strain-gauge technology offers excellent repeatability and precision 3D form measurement.
  • Zero reseat errors.
  • No lobing effect.
  • 6-way measuring capability
  • Stylus reach of up to 100 mm (GF styli)
  • Rapid probe module changing without the need to re-qualify the stylus tips
  • Life of >10 million triggers

The TP200 probe uses micro strain gauge transducers to deliver excellent repeatability and accurate 3D form measurement even with long styli.

The sensor technology gives sub-micron repeatability and eliminates the lobing characteristics encountered with kinematic probes. The solid state ASIC electronics within the probe ensure reliable operation over millions of trigger points.

The TP200B uses the same technology as TP200 but has been designed to have higher tolerance to vibration. This helps to overcome the problem of ‘air’ trigger generation which can arise from vibrations transmitted through the CMM or when using long styli with faster positioning speeds.
Please note that we do not recommend the use of TP200B with the LF module or cranked/star styli.

Principal application DCC CMM where high accuracy is required. As TP200 but where ‘air’ trigger events occur.

The stylus module is mounted on the TP200/TP200B probe body via a highly repeatable magnetic kinematic joint, providing a rapid stylus changing capability and probe overtravel protection.
There are three modules available, with 2 different overtravel forces.

Module SF (standard force) LF (low force) EO (extended overtravel)
Application  General use. Small diameter stylus balls or where minimum force is essential. Extra overtravel to enable the CMM to stop safely from higher probing speeds.
Comments Styli up to 100 mm long and ball diameter > 1 mm. Balls less than 1 mm diameter. Same overtravel force as SF.
Extra 8 mm of overtravel in probe Z axis.
