Tool Holders – A closeup
Tool Holder, Collet and Collet Nut
The collet is what holds the cutting tool in the spindle, simliar to the chuck of a drill. The tool is inserted into the collet and tightened with a collet nut. Our CNC’s are equipped with air assisted tool holders so we can keep a library of pre-measured tools in collets that can be quickly and safely interchanged when needed.
Tool (Cutters, end mills, drills etc.)
Tools make direct contact with the workpiece and remove material to mill out the object. Refer the course on CNC bits to learn more about the different types of cutting tools used.
The figure below introduces us to a collet spanner, one of the tool needed to tighten and loosen the collet assembly onto the spindle
