Hi All,

A bit of advise if possible:

I'm using Vectric Cut2D to do various 2D operations on a sub frame mounting block before going to 3D operations to do the "adding lightness" cuts. The part is 38mm thick and will be using 6082 T651 Aluminium and whilst I have used end mills to spiral into material before and straight peck drilling, I'm wonder if this is the best way as it can beat the machine up a little.

Also Vectric has twist drills in its tool database and wonder how I should using these on my machine considering my pillar drill speeds placard suggests way lower speeds than the 2.2Kw spindle normally runs at (or is even capable of).

Suggestions and advise welcome before I run a HSS twist drill at what I think is going to be way to fast (vectric's default speed for a 6mm bit is 12,000rpm ) and end up with half of it stuck in the aluminium

Cheers


Chris
