Titanium is a difficult metal to polish. It can be done in many ways; however, you are normally talking about long time cycles. Most of the samples we have run have been in high energy centrifugal systems. The cost of this equipment is relatively expensive. It can be done in vibratory systems but you a talking 24 hour cycles or more. The condition of the raw material is also very important. In most cases you need at least a 2 or 3 step process. If you need more specific info get in touch.

Dave, please tell us what you are doing, as it's hard to propose much useful with little to go on. We could say "try increasing the process time by 50 percent" -- but is that really helpful? Thanks.

Titanium implants can be easily electropolished by safe simple to handle method in environmentally safe solution. There are no problems in receiving the same rate of removal during continuous polishing one load after another. No burrs, no uneven material removal, no additional passivation afterwards, no surface contamination with abrasive materials. Contact us for more information.
