Thank you guys for your answers, you were very helpful.. I will explain what i decided to do... the idea is to make the X axis of the lathe to be a mill and the spindle will be turned with a servo motor reduced several times to increase torque (probably with a worm and gear to make impossible the spindle to move ), i don't really need high rpm... i think that maybe the maximum rpm would be 100 or 150, because there is no need to make it turn faster.
So, the idea is to use 2 servo motors, one for the spindle and another for the X axis, (Z axis could be a stepper, it's not critical) and yes it will be used for making the roughing process of the camshaft. The shape of the lobes, well.. we have data for some models.. others we have to find out how the profile is, but the idea is to model the lobe in solidworks for example and then use the postprocesor to make the g-code for emc2. I have a lot of doubts about this because we have only used emc for positioning and I/O in our grinders, and these ones have masters for making the lobes. But i think that i would use it as a milling machine, it's easier and fast for production.. so the idea is begin with the tests in the next weeks. I hope someday we can afford a cnc landis :( haha.. Thank you very much to all of you, and if you have more ideas or anything i would like to talk about it.. if i made improvements i will tell you! Best regards.
