Compact module changing touch-trigger probe, which allows the use of a range of stylus configurations and extensions to access features on complex parts.
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.
A compact, module-changing probe that uses strain-gauge mechanisms for higher accuracy and longer life than kinematic touch-trigger probes.
The TP200 system components are:
TP200 or TP200B probe body (the TP200B is a variant with increased vibration tolerance)
TP200 stylus module - choice of fixed overtravel forces: SF (standard force) or LF (low force)
PI 200-3 probe interface
SCR200stylus change rack
There is also an EO module (extended overtravel) which has the same overtravel force as the SF but provides increased operating range and protection in the probe Z-axis.
Features and benefits
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
TP200 / TP200B probe body
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.
Robust kinematic probes with M8 and autojoint mounting options.
The TP6 and TP6A probes have different probe mount options (M8 thread and autojoint respectively). Both probes are kinematic touch-trigger probes and have manually adjustable trigger force for optimum probe performance with different stylus configurations.
They can carry long styli (M3 range), are 25 mm (1 in) in diameter, providing substantial overtravel for excellent robustness.
RG2 and RG4 incremental encoder systems have a strong reputation established over many years for providing highly-reliable position feedback, even in conditions considered unsuitable for most open, optical linear encoders. They all feature the original Renishaw state-of-the-art filtering optics, with excellent immunity to dust, scratches and light oils on the scale. These systems are fitted as standard by many of the world's leading linear motion OEMs as well as being used in wide-ranging applications such as medical, machine tool, photovoltaics, semiconductor and flat panel display manufacturing.
RG2 is the name given to the range of encoder products that read 20 µm pitch scale types. The range contains a variety of readheads, which differ in size and scale options, including:
compact RGH20 and RGH24*
low-profile RGH20F and RGH25F**
* NEW: faster speed variants available.
**The RGH25F is also available as a UHV (Ultra-High Vacuum) version.
RG4 is the name given to the range of encoder products that read 40 µm pitch scale types, permitting even higher speeds and greater set-up tolerances. The range, which differ in size and scale options, consists of:
