RSP3-6 extended reach probe

Product catalog summary

Key Benefits

Reach: The RSP3-6 probe offers straight extensions up to 800 mm and cranked extensions up to 600 mm from the REVO’s A-axis centre of rotation.
Accuracy: Scanning accuracy typically better than 10 µm form error and 5 µm diameter error. Touch-trigger accuracy is typically better than 3 µm for both form and diameter errors.
Part of the REVO 5-axis System: Combines long extensions with 5-axis movements for enhanced part access and flexibility.

Enhanced Access and Inspection Capability

The RSP3-6 probe is designed for accessing deep bores and inspecting large parts. It supports both touch-trigger and 2D scanning applications with various stylus holders for straight and cranked extensions.

Test Setup Criteria

Stylus Used: Renishaw’s M2 stylus range.
CMM Specification: U3 = 3.1 µm + L / 250.
CMM Controller: UCC S5.
Data Filter: Harmonic simple cut off order = 60 UPR.
Artefacts Used: Ø45 mm calibration sphere and Ø50 mm ring gauge.
Scanning Speed: 5 mm/s for ring gauge scan tests.
Touch Speed: 2 mm/s for ring gauge touch tests.

Performance

Scanning of a ring gauge showed form errors ranging from 7 µm to 9 µm and diameter errors consistently at 3 µm. Touch-trigger probing showed form and diameter errors ranging from 2 µm to 3 µm.

RENISHAW.S apply innovation™ Renishaw pic New Mills, Wotton-under-Edge, Gloucestershire, GL12 8JR United Kingdom The RSP3-6 provides enhanced capability for accessing deep bores and inspecting features within large parts. It is available with a range of stylus holders for applications requiring straight and cranked extensions and can be used for both touch-trigger and 2D scanning applications. The other RSP3 probes within the range (RSP3-1, -2, -3, -4) can be used for 3-axis scanning with fixed REVO head angles during measurement, providing the REVO system with 3D-scanning (X, Y, Z) with crank stylus capabilities. It also allows different lengths of styli to be used whilst maintaining optimum metrology performance. RSH3-6-800 Key benefitsReach Available with straight extensions up to 800 mm from REVO's A-axis centre of rotation, and cranked extensions up to 600 mm from REVO's A-axis centre of rotation. Accuracy Scanning accuracy: Typically better than 10 pm form error (filtered) and 5 pm diameter error. Touch-trigger accuracy: Typically better than 3 pm form and diameter error. Part of the REVO 5-axis multi-sensor system Long extensions combined with 5-axis movements for better part access, and multi-sensor changing for increased flexibility.
