Think cross drill and/or cross tapping a hole in the bar your running...
Also known by some builders as "Milling".

fakeru;
Driven tools as they refer to a lathe are tools that are rotated under their own power in the tooling turret like the cutters in a milling machine. These tools are normally situated parallel to the z axis (axial) and the x axis (radial). This arrangement allows off center features to be milled, drilled or tapped in the same set-up as a part is turned. You can also get driven tooling heads that can be positioned at any angle between axial or radial to allow even greater capability. Normally a lathe with driven tooling also has a "C" axis or basicly a spindle that acts as a CNC rotary table would on a milling machine. This allows all kinds of rotary and polar interpolations to be performed. There are limitations to what you can do with this type of set-up unless you have a lathe with a "Y" axis and then you can do 4 axis machining within the size constraints of the machine. Tooling is expensive, I just spent $18,000.00 for 6 driven VDI 40 holders from WTO in Germany but the pay backs are there if you have the work for it. The turret also has to be capable of powering the tools (obviously) so there is additional expense for that as well. Mine is a Sauter 12 position with 6 driven positions in it. It gives you 4000 rpm, 5 hp and rigid tapping capability in all six positions. Hope this clears things up a bit for you.
