Vacuum Chuck on Surface Grinder

[Mancipia Mariae]

Has anyone had any luck setting up a vacuum chuck for surface-grinding non-magnetic parts? I saw a post of someone making one for an Ameribrade surface grinding attachment a while back and wish I could pull it up again to see how it was done.

I don't have any information on a vacuum chuck, but here is the method I use for grinding non-magnetic materials. I use a flat piece of steel and put a piece of painters tape on it. I also put painters tape on the non-magnetic part I want to grind. Then, I use a couple of drops of superglue and glue the steel to the work piece. Then, I put the assembly on the magnetic chuck and grind away. Since the superglue is between the painters tape, there is no residue on the surface. A bit time consuming, but I don't do this very often so I don't mind.

Depends what you grind .Sometimes just support from both side is enough , double tape work just fine also

steel is in that tool but you get idea , it can be anything non magnetic

double tape

just support , no double tape
