Can someone tell me how this chunk of Al is being held down?

There are no clamps, and the table does not seem designed for vac?
Cheers
Stephen.

I think they use aluminum magnents
It almost has to be vac, that seem to make the only sense of all the grid work sections.
What ever it is, it's doing a great job.

My father use to use a double back tape made by 3M for Fly cutting aluminum. No clamps! He said it was precision tape. If memory surves me right he bought it at Reid Tool and supply. He would wipe the mill table and work piece with acetone and apply the tape. He would lay the work piece on the mill table and hit a few times with a rubber mallet. The work piece had to be flat. The first time I saw him do this, I stood on the other side of the shop. To remove the piece he would slide a screwdriver underneath the piece in the T slots and pry it up. We never removed to much material this way ~0.02” max. Although it would depend on the cutter and feed rate and a touch of common sense.

Looks like a vacuum table. The slots/grooves you see are typically filled with gasket material to create the vacuum. It's a very generic fixture that can be used on many simple applications.
