End mills can be held by the spindle in several ways; a few of the ways
are shown in the figure below. On most machines, a draw bar is used to
pull a spring collet into a taper in the spindle. When removing
cutters, be careful not to damage drawbar thread and thread in collet.
Ensure machine is isolated before chancing or fitting cutters. Use gloves or rag to prevent cutting injuries when holding cutter during installing and removing of cutters. To fit cutter slide collet into spindle and tighten the drawbolt. Do not over tighten as collet will be damage. To remove collet out of spindle, loosen drawbolt, do not turnout completely. Tap top of drawbolt with rubber mallet to loosen collet out of spindle. Only turn out drawbolt once collet is loose. |
