Magnetic table or magnetic base kind of thing?

(1/3) > >>

PekkaNF:
Need an idea or inspiration on a grinding machine tool rest. Has to have a lever, switch or something to turn the magnetic flux on and off , to make placing the rest near lapping disc very easy.

Bit like this:

1: Like above, permanent magnet. Maybe a magnetic base, but they have often only one hard point. Not great for stability.  Maybe just can drill and tap two holes? Sides should be soft steel.

2: Sort of magnetic table? Just don't want to pay over 200 €/£/$ of sort of magnetic table.

Something like that?

What about these https://www.kjmagnetics.com/blog.asp?p=magswitch its a American site but you may be able to source them closer?

PekkaNF:
They look nice. Googled them fast, one place to get them here, but they are bundelt with featherborad and stuff - pricey, but they look right ar first glance.

I own a set, they were designed for a ground cable for welding, the magnet is ok but the mechanism is a little chiniezium your going to have to modify them yourself which you are more than capable of doing..


All the best

Just read further down at the explanation of how they work it may be you could make a more bespoke version for your project if you can source the magnets.
