Need to do Deburring of Titanium

I'm looking to deburr the ID of 1/8" and 1/16" titanium tubes. They have an ID of 0.061" and 0.031", respectively. We have been using chamfer bits but using the chamfer bits too aggressively reduces the wall thickness of the tubes, which is a problem for the 1/16" tubes as they will be orbital welded to the rest of the plumbing.

The burrs are typically formed during a sanding operation for facing the tubes. Do you have any suggestions for improving either the deburring or the facing process?

? Hi J Lin,

What is the Ti alloy type? What is the length of the tubes?

Q. G2 Titanium, tube lengths can vary, but the minimum would be around 20mm

A. If the Ti alloy is grade 5 ( 6Al- 4Va), then low voltage plasma electropolishing ( ultrapolishing) can penetrate inside the holes of 20 mm. Unfortunately this method does nor work for grade 2. However there is another method called high voltage plasma electropolishing. I think it will work for grades 1-4 ( pure titanium).

We call those "plasma" electropolishing, because in certain conditions plasma originates in between metal surface and electrolyte.

Q. I have to deburr small titanium housings with a groove inside after machining. Housing dim's. .132 x .166 x .130 inches, groove ID is .099 and hole thru ø.0685. I would appreciate any deburring solutions/ideas for my parts.

A. Solution depends on volume. Very small quantities may be worked with wheel systems. If you have a lot of parts, I suggest a mass finishing system. Processing time, equip. type and size again depends on volume. Media to use: ceramic.
