Rigged up for milling the surfaces one by one - I had to use conventionel milling (not climbing) because my mill can't do climb milling very well: Later I found out I had to add more stability: and I went along with the first face - and it gave me some very big "curling" chips and sounded just right. The next face - the one pointing down to the vice - gave my nearly no chips att all - and sounded no good - it just distroyed my tool ! I think the plasma cutting had hardened the steel too much for the tool (HSS) - could that be the case ? |

Thats a nice slab mill hope you can get a regrind, you could try a TC tipped facing mill to get the hard skin off, or if you've got a shaper try that. Good luck Stew |

I got a little longer with the main part :coffee: : I'm NOT so proud of the surface finish, but I haven't got my destroyed cutter grinded yet :hammer: - I used another one - I think it's called a face mill - that's why it look so rough ! I used a R6 to rounding the edges and I think that's just the right size. :thumbup: |

Doesn't look rough to me! Is that a centec mill your using? I have one like that with a big facing cutter the same but it is knackered also, leaves a nice ridge down the middle of the cut face on mine! Nick |
