Has anyone worked with the Pre-made L-Styli?

[[Au...]]

I'm looking at them as a possible replacement to the disk probes for particularly small grooves, partially because of the inability of our current disk probes to get into some of the finer grooves, and partially because using disk probes with calypso is just not ideal and a bit of a pain. Looking at the catalogue I noticed https://shop.metrology.zeiss.com/INTERSHOP/web/WFS/IMT-US-Site/en_US/-/USD/ViewProduct-Start?SKU=626113-5000-187 this item. Before asking for my superiors to order this pricey probe, I do want to know how it performs in the real world. namely how you ensure that its rotated to the machine axis? are the Zeiss threads precisely measured to clock the probe? or would it be a matter of either rotating the head to the angle closest to making the probe aligned, and using a conical adapter to align it on a duramax? Any more significant info on these probes would be appreciated, or if Zeiss already has documents on this, I am a huge fan of RTFM.

You need a rotating joint, to clock it to your desired position.

Or you can Macgyver it by trying different extensions until the the stylus lines up the way you want 🙂

True.. I have used shims to get the desired rotation angle that I want, as well 🤷‍♂️. The rotary joints are just 1000% easier.

Yeah I've done the same. But seeing your post I've just ordered two joints 😉

I was using L styli configured by myself 

It was M5 Thread from VAST heads (this big solid ones) but with extension it was used on L3 VAST XXT (with M3 thread plates) 

It was L80 D0.5 

When 0.5 broke i bought starprobe from Mitutoyo (need break of styluses to use them)  and used superglue to stick it, Zeiss never liked it too much, but it was calibrated with good reasults and did good job.

Like others have mentioned, you need a rotary joint, then its easy.

I use an Indicator and indicate the L to one axis along the B length (Minus the tip) to within .001" per inch of travel capable on the stylus.

I use this same method for all styli that are using other axis than Z. You can only indicate one axis; all the others will fall in quite close.

Other than that, the MLE should be considered from DG, not just DS. This will be helpful when the stylus is past the ML to prevent shanking.

Mornings!

I have 3 L-Probes we use for measuring Ball threads ( Self-Centering method ). Getting these aligned for us is running a probe qual and looking at the X-Value. I don't use a rotary joint but instead loosen the 3 screws on the top plate and guess. I usually aim for anything ≤.004" ( .102mm ).

That said we have had pretty repeatable numbers using this probe. The real issue was the additional Ref-Sphere cost. We couldn't qualify our probes on the 30mm sphere so we had to by a 5mm sphere.

 

Edit: I missed the XXT wording. A rotary adapter would be needed, my bad.
