    Question Ball screws & linear rails.

    http://cnczone.com/forums/showthread.php?t=100925

    This is my build in progress.

    I would like to find a store that sells ball screws as well as linear rails. Please shoot me some popular suggestion with good deals.

    I need pillow blocks (end supports? correct me if i'm wrong) for all the ball screws as well. I have no clue what the difference between a simple pillow block and a fixed block is, and when it comes to the machined ends i'm lost. I do know that i need a ballnut flange that is square so i can bolt it to my gantry.

    Some one enlighten me.

    Thanks.

    I read the entire article on ball screws and now i basically get a decent understanding of whats going on with the fixed end, simple end etc. Thank goodness. Now where should i go to buy all this stuff?

    Are those ball screws and end supports they sell any good? The price is awesome. Couple those with some Hiwin linear rails and blocks from:
    http://www.automation4less.com/linear.htm (Heavy duty series)

    and i would assume i would have a fairly decent motion setup...

    As far as the "end machining" on the ball screw i want to attach a gear to it so i can couple it with the other ball screw, so i will have a dual ball screw setup pushing the gantry to help eliminate binding. Do they sell them already machined with a single sided flat surface and keyway or...?

    thanks for your help.
