Cleaning and finishing procedures for
bone screws
++++
Interested in finding out standards relating the pre and post
fabrication cleaning procedures of stainless steel 316 L or 316LVM
used in the fabrication of bone screws and bone plates. The process
available in this country is an "oily" one, which means that I must
remove it before any further process. Wondering as well if the
electropolish procedure will clean such oil??. If not, any references
about the process to remove such oil????

Here in the U.S., this would be subject to all kinds of standards,
including U.L. and ASTM. The electropolishing step per se is not
intended to remove oil, but a cleaning step is universally applied
before electropolishing.

My answer to you does not address the safety or medical standards
industry; however, as a very cheap, inexpensive and simple deburring
process, you might want to try part on part mass finishing your parts
without any liquid at all. Keep an eye on your time cycle and you
will still have to clean your parts after processing.
