3.1.2
Lathe Setup - Workholding
A drawback collet is required for bar feed applications. The Bar Feeder holds the push rod
in place while the lathe drawtube clamps. If the collet does not pull the bar stock against
the push rod when the drawtube clamps, length variation can occur and accuracy cannot
be guaranteed.
NOTE:
Your collet should also have a chamfered lead-in for smooth bar
feeding.

that came with your workholding.
