Good info. Thanks! I guess i'll use a roughing bit then, since i want to reduce my machining time as much as possible. The machine has 24000 rpm and weighs about 1.6 tonnes, so i guess i could harness the capability of a roghing mill
No idea what sort of machine you are using but at that sort of weight sounds like an industrial type machine rather than a hobby machine, the 24,000rpm is spindle spped & isn't really relevant, a very low power spindle could easily have a high speed.
Unlikely to be the case with your machine though, if you want to reduce machining times then the extra expence of a roughing bit will certainly be worth it for you especially if this is a business where time equals money
Gerry is the expert not me but I still don't believe that there would be much gained on a lot of the hobby type machines that people on the forum seem to be using like Piranha's & x-carves, no personal experience with either type but neither seem to be rigid enough or capable of speeds that would make to much difference
