⭐ Styli in focus ⭐
50 years on, ruby still rules precision 🔴
When Renishaw launched its first touch trigger probe in 1973, the very first styli we produced were ruby; and for most applications, ruby remains the benchmark for precision measurement.
Why customers still choose ruby:
✅ Consistent accuracy – ultra smooth, highly spherical balls deliver repeatable results; we use grade 5 as standard (0.13 µm deviation) with grade 3 (0.08 µm deviation ) available for ultra high accuracy.
✅ Proven durability – outstanding compressive strength and resistance to mechanical wear keep you measuring for longer with fewer changeovers.
✅ Right size for the job – standard diameters from 0.3 mm to 8 mm, plus custom sizes to match your feature inspection requirements.
And because the application drives the material, we also offer silicon nitride, zirconia and OPTiMUM™ diamond tip options for aggressive scanning or material specific challenges; so you get reliable data, whatever you’re measuring.
