zero game counterpoint guides

[andreabs91]

hi to all, as the first project our teacher has assigned us as project the realization of a contorpoint that coupled to a divider will act as a 5th axis of a cnc machine. the problem on which we are stuck is simple, the guides do not have to be commercial and I have to have a game adjoining to zero. according to you of the guides like those in the image can go? the counter of case 1 is that the seat could fill with dirt, that of case 2 is that, having the counterpoint to hold a load of 500 kg, there could be the risk of deformations.

What kind of guide do you make up? once, when you were poor but you wanted precision you made swallow tail guides with lard of registration. now that we have evolved there are linear recirculation guides of balls or rollers and have excellent characteristics since they make us the axes of machine tools. go to the schneeberger guides that are the top of range as precarious and as capacity of low deformations under load.

the approximate zero game is made in the linear recirculation guides through preload of the desired elements and they are fine. if your prof wants to break the boxes only because he has 50 years old ideas do him the tail of swallow but do not invent profiles like what you have scanned because they are not recordable. those shapes there makes it igus but not good for a tool axis, they serve to move objects with precision +/- 0.5 mm and you have needs +/- 0.01

thanks to the answer but we solved with a system made by a rectified bar and a cart with bronzes, a solution that was accepted by the professor

I imagined that he accepted it, he did not understand that it is more precise the recirculation skate of balls or rollers with preload of a bar guide rectified with bronze.... I hope that they are not all so new profes otherwise we are hurt
