2015 Torni Tacchi HD/3 90L CNC Lathe

The Torni Tacchi HD/3 90L is a heavy-duty flatbed CNC lathe built for shops that need to turn and mill large-diameter, long-shaft workpieces in a single setup — a machine with a reputation for rigidity and precision that has made it a go-to platform in energy, oil and gas, and heavy industrial environments. This 2015 unit features a 45.27-inch maximum swing over bed, 29.52-inch swing over saddle, and 393.70 inches between centers, with a 67 HP main spindle drive producing 6,570 ft-lbs of torque across a 3–1,000 RPM speed range through three geared ranges. The Siemens 840 DE SL Solution Line CNC control runs the full machine, including a Baruffaldi TBMA 302/12 twelve-station disc turret with live milling capability at 3,000 RPM and 20 HP. Heidenhain linear scales on the X and Z axes ensure positional accuracy, while three Morari programmable self-centering steady rests with longitudinal positioning handle workpiece support across the full bed length. Additional equipment includes 24.8-inch and 12.4-inch Rohm chucks, a Renishaw TS13/RMP60 tool probe, tailstock quill thrust compensation, telescoping steel way covers, a full-length chip conveyor, and an automatic lubrication system. The HD/3 90L represents a significant step forward from the earlier Tacchi HD/3 Series 90 machines built in the late 1990s and early 2000s, which typically ran Siemens 840C or 840D Powerline controls with more limited HMI capability and slower processing speeds. This 2015 build benefits from the Siemens 840D SL Solution Line platform — a fully integrated CNC architecture with faster block processing, modern Ethernet-based communication, and a more intuitive operator interface compared to the Powerline generation. The addition of live milling with Y-axis capability on the Baruffaldi turret is another upgrade over older HD/3 configurations that were often turning-only or required secondary operations for milling work. Buyers looking at this machine are getting a modern, done-in-one heavy-duty lathe that eliminates the need to move large parts between machines — and at a used price point well below what a comparable new Tacchi would command.
