Video: High-Torque Titanium Hogging
Judging from the results of this machining test, the T-Rex horizontal boring machine (HBM) spindle is aptly named.
A while ago, I wrote a short article about the relationship among speed, power and torque during machining, and how to effectively judge the capacity of a spindle for heavy metal removal in difficult materials like titanium. (Hint: Pay close attention to the power curve chart!) As part of that article, I highlighted one example of a spindle designed specifically for this task: The T-Rex from Fives Giddings & Lewis, which achieved 33.1 in3/min. in a recent titanium test cut.
The written word, of course, can’t offer a visual of the cut or the sound of insert meeting chip. Short of being there, that kind of thing is the sole province of videos like the one above, which enables you to draw your own conclusions about the aforementioned test cut or simply enjoy some impressive machining footage.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Simple process considerations can increase your productivity in milling titanium alloys.
Rather than start with the machine, says Boeing, start with the tooling. For titanium workpieces and other high-value parts, a simple spreadsheet of tools and operations might be the most valuable resource for machining center selection.
