[QUOTE="DMC, post: 66226, member: 430"] Climb-Milling increases tool life, by not scuffing the surface and actually bending the material before the flute actually grabs and begins to cut. Instead...It takes a big bite right from the beginning and then the chip gets thinner down to nothing as tool moves forward. This is much more force being applied to the mill's frame and axis motors and such vs. Down-milling. You need very strong mill to control the tool. Has to do with Physics, or some crap like that? LOL Down-milling (A.K.A. Conventional-milling) will make more heat and reduce tool-life.....but makes better surface finish for some situations, like the final finishing of a polished Metal surface (Full cast crown). Almost like swaging metal or work-harding a material. It is easier on the mill and forces are reduces. (Good for the Roland and other desk-top mills) Maybe not too good in some instances. ex. For bulk-milling of metals, I would only use Climb-milling. Otherwise, I'd go broke in buying tools. Maybe I would switch to Conventional for occlusal surface of Full cast, or maybe the internal spiral finishing/. [/QUOTE]
