Hello,
I was wondering if anyone had a way to convert the (2x) 7° grooves in in the ID of this part to an equivalent threads per inch. We are looking to do these in a lathe and need threads per inch for programming. Thanks in advance.

Tangent of groove angle is equal to part circumference divided by one thread length. Therefore threads per inch will be tangent (7)/(pi×diameter) . But i don't guarantee it's correct. My reasoning - roll the part over piece of paper - groove will form a triangle with cirqumference height and one thread cycle length base
Sorry - i somehow misinterpreted the drawing. Thought its a long thin spindle not a ID of sleeve. In that case it should be tan(90-7)/(pi×diameter )
