Cutting Titanium
« on: August 14, 2011, 03:49:48 PM »
anyone have a good tip for cutting titanium that does not develop heat?  tried a dremel cutoff wheel - obvioulsy got hot......cant get a hacksaw blade in there.......any other ideas?

I am trying to cut the nose ring backplate out of a yatsenko but leaving the ring in place to hold the nose together - to much heat will remove the glue and paint - so want to avoid it....

 I don't know the whole situation here Wynn. Controling heat in Titanium is going against nature. Titanium is used extensivly in heat exchangers because of it's ability to draw heat away. It's a natural at conducting heat.
 Can you post a picture of the problem. Maybe a make shift heat sink will draw the heat away from the cut.

   I cut it with a hacksaw. If you go slow, it won't develop a lot of heat.

If space is an issue you could try some diamond wire saw blades. They are much more compact that hack saw blades and available in different diameters. Attached is link to an example.

 But that nose ring is not titanium, its hard anodized aluminium. Just grind the oxide away with a Dremel drum sander, then the hacksaw blades last longer. Finish with file. L

Has anybody here tried to machine titanium on a  sherline type hobby mill? I wonder what type of cutter works and what feeds and speeds.  It would be nice to cut landing gears from sheet Ti on a small mill

I machined some titanium in a lathe once and just for interest's sake I took a shaving and put a match to it. It burned like magnesium.

Ti alloys work harden very quickly- destroys the teeth on a Hacksaw blade. Best bet is to find a local job shop that has setup for CNC abrasive water jet or a laser cutter. Laser cutter used to cut our kits doesn't have the power- but there are many that can cut sheet Ti.
