    Default Lead Screw - slight galling causing manufacturing

    Hi,

    I've had a few issues with galling which has caused the lead screw to loose its effectiveness.
    The machined parts haven't been to spec. Can someone recommend a reliable lead screw brand?

    What type/brand of machine are you running? Is the lead screw you have just an ACME or Trapezoidal screw or is it a ballscrew?

    What makes you think the problem is from the lead screw? Other factors can cause problems like cutting tool geometry. feeds and speeds,part or tool ridegitey, spindle bearings, other.

    A little thrown off as this thread is in "Additive Manufacturing/3D Printing" but nonetheless I agree with digger doug as pictures of what you are describing would be helpful.

    A printer goes many ways/travel direction..mostly a lathe goes/travels one way so after slack is taken up it should ride smooth.

    Please see about 4 posts before that.
    Its a trapezoidal lead screw in a lathe machine.

    You and this bloke, should get on like a house on fire. Surely you have both had strokes? Because neither of you make any sense.
