Using the boring bar! It's worth noting that Titanium CAN catch fire in a lathe!! | Using the boring bar! It's worth noting that Titanium CAN catch fire in a lathe!! | ||
Thus, it's essential to keep things cool with the coolant and to clear the titanium hairs. | |||
My big time-waster was not finding a way to shorten the stock before starting my adventure. Everytime I did something, runout would build into the spin. (from 0.005" to a millimeter it seems) This would lead to an inconsistent loading on the tool, and perhaps the impacts of the tool leaving and hitting the titanium were hardening it and causing the chatter to build. | My big time-waster was not finding a way to shorten the stock before starting my adventure.

I ended up figuring out a strategy though! If I advanced the tool position (radius of the ring) while the boring bar is inside the ring cavity | I ended up figuring out a strategy though! If I advanced the tool position (radius of the ring) while the boring bar is inside the ring cavity the chatter was much reduced! | ||

The runout resulted in a difference in concentricity between the outer and inner diameters of about 0.005"! However, it kindof looks intentional! | The runout resulted in a difference in concentricity between the outer and inner diameters of about 0.005"! However, it kindof looks intentional! | ||
In the picture above, you'll see some markings inside. That's a combination of the chatter-marks from the boring, and leftover purple from the torch that didn't get removed in the troughs. | In the picture above, you'll see some markings inside.
