Ever wonder where NASA, Apple or HP gets their parts from? I have a few friends who are engineer majors and it is so interesting to listen to them talk. It seems way over my head because most of the time I have no idea what they are talking about, until my friend explained a bit to me. He was telling me about this part called a Ball Spline that provides linear motion (smooth movement) throughout a contraption.
He got into explaining all the different kinds of ball splines: block, cylinder, flange, rotary, and two cut flange. Let me just tell you I am glad him and his friends know what they are doing/talking about because I struggled. I’m sure with the proper classes and learning I would understand much more. But I thought it was pretty impressive that most of the parts these guys were talking about are used at prestigious companies such as Bose and NASA (just to name a few). It’s interesting to get a new perspective on the day to day items used.
