This indicates that something in the structure is loose, or very weak. At some point, the clamp/table/head/tower/chuck assy, or multiple items, provides enough wobble to cause the cutter to bite into the part with sufficient grip to move it relative to the vise.<br /><br />Chuck up a rod with an indicator against it, and start pushing or pulling on the end of the rod. Determine if it deflects more easily in X or Y. Repeat this with something in the vise.<br /><br />Check the walls of the slot it was cutting. They should be flat.

I would also look at your clamping, since that seems to be the weak point in the forces you're unleashing. And check your spindle speeds. you may be taking too big a bite too slowly.Mauserhttps://www.blogger.com/profile/11732614352398473302noreply@blogger.com
