Tumble polishing silver: The OTEC machine

Hello all

For a very good and fast polishing machine, which combines magnetic
polishing, wet grinding and dry polishing with for instance wall nut
shell.

See http://www.otec.de I have bought the OTEC maxi. This one is 3
machines in one and is working very fine and fast.

Maybe for some of you who are in need of small series of production.

Greetings,
Martin Niemeijer
