John, You seem to me to use a large amount of force to lock your tool in the spindle. Could you comment please? Mosey |

Hi Are you referring to the milling machine I like to tighten things up properly but not to tight The draw bar key only has a short handle John |

Mosey --- End quote --- I noticed that as well. Plain collet nuts need a little turn to undo but nothing like that normally and the ball bearing ones I now use far less than that. In fact for some operations on small stuff I can get away with tightening and undoing by hand! Talking about the lathe here, not the mill. |
| mosey:
Actually, I'm talking about both. How much is right for the mill when using ER collets? Mosey |
| doubleboost:
I use R8 collets in the mill The way I tighten mine I have never had a cutter "slip turn" in the collet Same with the ER in the lathe I tighten nuts and bolts all day for a living I think it is just a feel you get for things Using a standard ER spanner I think it would not be possible to over tighten the chuck Thanks for the interest John |
