Hardinge SV-200

The Hardinge SV-200 pairs an 8 inch (203 mm) chuck and 51 mm (2.0 in) bar capacity with a long bed: maximum turning length and Z travel are both 530 mm (20.87 in), against a maximum turning diameter of 312 mm (12.3 in). It weighs 5,000 kg (11,023 lb) and runs on hardened and ground box ways.

That weight is the first thing to notice. For an 8 inch machine, 5,000 kg is a lot of iron, and together with box ways it points to a lathe meant to stay stable under heavy cuts and to hold size on finishing passes. The spindle is listed at 15 kW (20 hp) and 5,000 RPM on an A2-6 nose, with concentricity of 0.003 mm (0.0001 in) TIR. Torque is not in the table, so low-speed roughing capacity cannot be judged from these figures alone.

The length raises a practical question. A part approaching 530 mm held only in the chuck needs support at the free end, and no tailstock row appears in the listed figures. Establish whether the machine in front of you has one before planning shaft work. X travel is 175 mm (6.89 in).

The turret has 12 stations, and the table does not mention live tooling, a C-axis or a sub-spindle, so plan on turning operations only. Rapid traverse is 20 m/min (787 ipm) and the listed control is a Fanuc 0i-TF Plus.
