Insight: CNC Threading - For Milled And Turned Parts

alt=""

At the most basic level there are two types of machined threads - internal and external. But when considering threads for your part there are a number of factors to ponder, such as:

  • size of threads in UNC, UNF and metric
  • maximum depths
  • whether the thread can be added before or needs to be added after manufacturing
  • inserts and how they affect hole diameter and depth etc.

This week's video looks at the key details, to help you learn what's possible when it comes to CNC threading.

15.11.19

Insight: Fine Detail - 3D Printing Fine Resolution Features
