Schaublin B32 collet markings

str · Oct 28, 2020

Hello,

I've got s Schaublin B32 collet and B32 expanding arbors sets with a Schaublin 150 machine.

The collets marked with a logo, size and letter "U".

What does "U" marking means?

The B32 expanding arbors have just a logo and size.

U is their higher precision class, twice as tight as normal grade.

Thanks for info and respect for your country - a motherland of Schaublin.
