U-Comax heads are used for inner facing, outer facing, back-facing, inner and outer turning operations, grooves, phonographic grooves, cylindrical and conical threading, conical and variable boring, concave and convex corner rounding, through interpolation with the other the machine axes.
I have a D'Andrea TA120, which I love. Its got the big red handles. Regarding to what Sean says, I have seen pictures of the one by Wohlhaupter that also has the big red handles. It is so similar that it occurred to me that they are identical. D'Andrea has a web page that shows what assessories are available.

These are very sensitive and radial correction of 1 micron can be effected directly on the machine and easily read on the vernier scale.
The entire D'ANDREA range comes from its headquarters in Lainate, just outside Milan: TA-CENTER, TA-TRONIC, U-TRONIC, U-COMAX and AUTORADIAL facing and boring heads. The high precision modular toolholder system MODULHARD'ANDREA and the complete balanceable toolholder system for high speed applications TOPRUN, MONOd', MONOforce and MCD'.
Can you elaborate some on what you are trying to do? I could share my likes/dislikes regarding Sandvik Duo-bore, Kennametal Mod-bore, Iscar ITS-bore (AKA D'Andrea), Parlec twin boring (AKA Valenite VPB), Valenite vari-set, and Komet ABS twin heads among others but if there is a lot of core shift and moderate length to diameter ratios helical ...
