Module 3.1 - Components for tool setup
Before you can use a tool and place it in the tool library, it must be assembled securely in a tool holder.
Tool holder
The tool holder is the interface with the spindle.
The tool holder nut is used to tighten the tool in the tool holder.
The collet acts as a clamp that tightens around the surface of the toll when the nut is tightened during assembly. It is tapered to mate with the inside surface of the tool holder.
Cutting tool
The cutting tool is inserted in the collet during the assembly process. The depth of insertion is variable.
