Styli and Probes

WD Hearn provide the full range of Renishaw, Zeiss and Faro Styli for all probing applications. Thread sizes ranging from M2 to M6 allows for replacement of any standard, and majority of specialised probing systems on either CMM, machine tool probe or articulated arm systems. We also have a range of styli material configurations, including standard ruby tips, silicon nitride or zirconia, with stainless steel, tungsten carbide or ceramic stems to suit any application. 

Custom styli with specialised threads and lengths as well as additively manufactured styli for complex metrology applications are available on request. 

If you are unsure of what styli you should be using for your application, feel free to contact us for some expert advice on styli selection and applications.

Zeiss Styli

Aside from the hundreds of available styli in the Zeiss range, Renishaw also supplies a wide variety of accessories for the Zeiss range of probe heads. This includes styli holders and extensions, knuckles, cubes, adaptors, as well as an assortment of other tools and accessories. We are pleased to announce the introduction of styli and adaptor plates for the Zeiss Vast XXT scanning sensor. TL1, TL2 and TL3 adaptor plates are available along with a vast selection of M3 styli designed specifically for these plates.

 

 

 

 

TP20 Probe

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. The stylus mounting thread accepts styli from the Renishaw M2 range.

TP200 Probe

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.

TP200 stylus modules

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 two 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.

SP25M Scanning Probe System

At only 25mm in diameter, the SP25M is the world’s most compact scanning system and comprises two sensors in a single housing. Users can switch between a choice of five scanning modules (which can carry M3 styli with lengths from 20 mm to 400 mm) and an adaptor module that is compatible with Renishaw's TP20 range of probe modules. This capability enables scanning and touch-trigger probing in a single probe system.  The SP25M's compact size and autojoint mounting makes it compatible with the PH10M PLUS / PH10MQ PLUS and PH6M probe heads. It can also be mounted on a multiwired extension bar. Together, these combinations permit excellent reach and access to part features.
