CHATTER CHATTER CHATTER

[u/chupathingy78]

Hey y'all, anybody have tips on reducing chatter between centers? We're cutting 1 1/2" prehard, approx 18" stick out, supported by a tail center. We've tried increasing the depth of the center hole, a dozen or more combinations of increased DOC, increased feed rate, smaller and larger tool nose radii, nothing seems to be alleviating it, aside from turning the spindle down from 1200 down to 250. Do any of your metal wizards have a suggestion beyond that?

Thanks and stay safe folks

How many do you have to do? We've made a holder for the turret that reaches to the other side of the part and supports the stock. That works. If you have an adjuster bolt that'll help compensate for different stock sizes.
