Scanning with Ruby on Hastelloy Ok?

[TK_Fire]

I have a Hastelloy part that I want do some scanning on.

Ruby tip is ok to use?

[RIDER]

I would say yes. I use rubies on inconel all the time. Here's what Renishaw says...
Ruby can suffer adhesive wear (pick-up) on aluminium under extreme conditions, but performs well in most applications. • Ruby is the best material on stainless steel and titanium. • Silicon nitride is a good substitute for ruby in extreme aluminium applications, but suffers from abrasive wear on stainless steel and cast iron. • Zirconia is the optimum choice for scanning cast iron components. • Tungsten carbide also performs well on cast iron.

is it cast? if it's cast you might want zirconia.

[TK_Fire]

No, it is a machined surface. I was more concerned about if pick up would be an issue as i have to use a Ø1mm tip.

I've only ever used ruby when probing nickel alloys (both on-machine probing and CMM use). We have been using Ø3mm ruby x 50mm ceramic shank stylii for the past 20 years on some of the machines and have only ever replaced 3-4 over that period, all due to human error and all failed by a clean break on the shank. Our CMMs were outfitted the same. This was on cast surfaces, machined surfaces, ECM surfaces, Inconel, HastX, Waspalloy, PWA alloys, RRC alloys, single crystal, directionally solidified parts, etc.
