Tube Interior Micro-Finishing
Dave Davidson | dryfinish@gmail.com | 509.230.6821

Modified centrifugal barrel finishing equipment is now being utilized to develop precision micro finishes on the interior of tubes and cavities for demanding applications such as particle accelerators. See the video as an example of one such application:

This breakthrough process utilizes specially modified variants of the equipment and materials discussed in the SME MMR and SME-Spokane video shown below
