SP25M (Scanning probes system)
At only 25 mm in diameter, and with a range of scanning and touch-trigger modules, the SP25M is the world's most compact and versatile scanning probe system.
The SP25M comprises two sensors in a single housing. Users can switch between a choice of four 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/MQ 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.

SP25M modules and stylus holders A range of module kits allows SP25M users to build up their probing capability over time. Each SM25-# scanning module is optimised in terms of gain and spring rate to suit the range of stylus lengths specified. For every module, there is a matching SH25-# stylus holder. The SH25-3 and SH25-4 stylus holders are constructed with a fixed carbon fibre stem to which an M3 stylus is mounted, selected to provide the correct working length. Whilst the SP25M can carry cranked (non straight) styli configurations when using SM25-1/2/3/4 scanning modules and the original standard stylus holders (SH25-1/2/3/4) but for optimum metrology where larger offsets are required Renishaw recommends the new SH25-2A/3A/4A range of stylus holder, specifically designed to meet the challenges posed by such stylus arrangements. |
