Hi, the title pretty much says it all. I didn't had any sucess searching the web for this information, i designed my ATC using a CAD from a friend of mine that he said it had the dimensions correct.
But i decided to investigate a little and see if i wasn't making any mistakes.
Then i found this website:
Techniks ISO20, ISO30, ISO40, and SK30 Collet Chucks
It has some CAD files and i downloaded one to check the dimensions were equal to my random ISO20 tool holder CAD file.
I checked the angle first, on my CAD file it reads 16° on the TECHNIKSUSA CAD file it measures 17°.
Can anyone point me to the matching pullstud and correct iso 20 taper dimensions ?
