Renishaw - TP20
The TP20 is a compact 5-way or 6-way kinematic touch-activated probe system.
Technical Description
The TP20 system extends the ability to quickly change probes for manual coordinate measuring machine (CMM) users. For automated CMM users, software from machine vendors supports automatic probe changing in most TP2 or TP6 applications.
- Reduced cycle times are achieved thanks to quick probe changes without recalibration.
- Optimize probe and measuring head performance with seven dedicated probe modules.
- Easy upgrade for all Renishaw standard probes.
- Compatible with existing touch probe interfaces.
- Mounts on Renishaw autojoint probes with PAA adapters/extensions.
- Performance measured to industry standards.
- Provides collision protection in X and Y directions.
- Compatible with Renishaw SP25M scanning probe system
