aluminum thread

[ansyolitico]

Hi.
I would have a big doubt

in dimensionaling a linear axis, I find myself where to choose as a structure material on which to lay linear guides, aluminum

Now from the remains of one I remember that it has a more plastic than elastic behavior. my greatest fear that even going to strain the fillets, since it has several cycles per day, go to yield everything or deform after a tot of time compromising everything.

I am not super expert on structures, but I have never seen structures that work hard to be made of aluminum. I don't want to say stupid but it's a big doubt I have

Sometimes on the aluminum pieces you put the helicoil threads or threaded compasses of a kind, also to improve the resistance to disassembly or reassembly in addition to the problematic you describe.

You can also use the fixed-type thread inserts that you can also use to put screws on thin thicknesses or to add "vites" on non-forable visual components.

and then aluminum structure means little...I when I make them are welded, piastroni ....pochi profiles etc.
some calculation to the structure must be done...can not only be beautiful.
skates and screws that last year? if it is all at the limit is different and if instead it is all cast iron panties another.

therefore usual thing to have high safety co-efficiency. Just that if you choose a guide of 30 screws are those, m8, you can't make a big deal, unless you use screw and nut. I don't know. The gudel axes are all steel. I think it's more for an elastic/engineering/stabilised dimensional module factor than anything, but any axis is made of steel. Then it goes well there are festo boards, rollon etc. but it is light stuff.
