HAAS LATHE:
TL-25B with live tools. A current machine process of ours - cutting scallops on an o.d. - we can cut at 20"/min 3200rpm - climb cutting - N-mill is a 3/8 dia. YG1-V7- with no problem on a vertical mill. When we try to make the same cut on the TL-25 at that speed we get chatter. In order to achieve the same quality of cut we need to slow down to 5"/min at 1250 rpm. Now the coupling for the live tools has a bunch of slop (maybe .06 backlash) could this be the reason? If so does anybody have a possible fix? -
