Savings: N/A
Combining long stylus reach with ultra-high accuracy performance, SP80 is the first-choice scanning probe for many applications.
SP80 is able to reach deep into parts by carrying styli up to 1000 mm long and 500 g mass, including star configurations which do not require counterbalancing. Renishaw’s M5 styli products are designed to complement SP80 and ensure peak performance.
Renishaw SP80 Scanning Probe System Features
Features
- Ultra-high accuracy measurement, provided by digital scale and readheads – system resolution of 0.02 µm (79 µin)
- Long stylus carrying capability for access to deep features – up to 1000 mm (39.4 in) and 500 g (17.64 oz) mass on SP80
- Unbalanced stylus configurations do not require counterbalancing
- SP80H variant mounts to horizontal quill – styli up to 500 mm (7.87 in) long and 500 g (17.64 oz) mass
- Isolated optical metrology for direct accurate measurement of stylus deflection
- Low inertia mechanism for excellent dynamic response
- Passive scanning probe with no motors, giving improved thermal stability and reliability
- Bump-stop crash protection in the Z axis, together with a detachable stylus holder for XY crash protection
- Adaptor plates enable rapid interchange between SP80 and PH10MQ PLUS motorised head
- Kinematic stylus changing for repeatable relocation of the optimum stylus configuration – removes the need for requalification
