Hardinge Talent 10/78L

The Hardinge Talent 10/78L is a 10 in (254 mm) chuck CNC lathe with a 78 mm (3.07 in) spindle bore and bar capacity and 650 mm (25.59 in) of maximum turning length. The listed figures give it a 300 mm (11.81 in) maximum turning diameter, 200 mm (7.87 in) of X travel and 650 mm (25.59 in) of Z travel.

The spindle is listed at 15 kW (20 hp) with a maximum torque of 250 Nm (184 ft-lb) and a top speed of 4,000 RPM. That is a torque-biased rating for the bore size. It suits roughing large bar and chucked blanks more than fast finishing of small diameters, where 4,000 RPM caps the surface speed. Workholding is listed as collet-ready with a 10 in hydraulic chuck.

Two rows need a careful look. The tooling system reads gang-tool flat slide, so tools sit in a row on the cross slide and share the 200 mm (7.87 in) of X travel with the part diameter; a long tool lineup and a large workpiece compete for the same stroke. And both live tooling and the programmable tailstock are listed as optional. A shaft near the full 650 mm (25.59 in) turning length needs tail support, so check that the machine in question has it.

Rapids are 20 m/min (787 ipm) in X and 24 m/min (945 ipm) in Z, the control is a Fanuc 0i-TF, and the machine weighs 3,800 kg (8,378 lb). Confirm the listed figures against the machine's own documentation before planning work around them.
