Tumbled discs, untreated on left, tumbled with Multi-Etch on right.
Here's a labor-saving technique that can be
achieved with a vibratory tumbler filled with
ceramic media. It's good for cleaning hundreds
of small parts all at once.
After
mass finishing your titanium parts to radius or
round the edges, the result is deburred and
nicely rounded edges, but very dark titanium.
Drain and rinse the parts and the ceramic media.
Then, rather than dipping each part once at a
time into Multi-Etch, reload your tumbler with
the ceramic media and add one cup of Multi-Etch
per 8-10 cups of media. The key is to moisten
the media with the Multi-Etch. Add the dirty
titanium parts and tumble 10-20 minutes, which
will produce significantly brightened titanium
parts.
Multi-Etch will not etch the
ceramic media but it's best to clean and rinse
between operations.
