How much does the Hardinge Conquest T51 cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Hardinge. Configuration moves it a long way.
Overview
The Hardinge Conquest T51 is a box-way turning centre with 51 mm (2 in) of bar capacity, an 8 inch (200 mm) hydraulic chuck and a turning envelope of 356 mm (14 in) in diameter by 508 mm (20 in) in length. It does not appear on Hardinge's current product pages; use the listed figures as a reference and check them on the machine.
Torque is the figure that defines the spindle. With 175 Nm (129 ft-lb) from 15 kW (20 HP) continuous and a top speed of 5,000 RPM, the drive is weighted toward cutting force at mid-range speeds, which is what turning 51 mm bar or a casting near the chuck diameter needs. The A2-6 nose is listed as 16C collet-ready, and collet runout is given as 3 microns (0.00012 in) or better.
Z travel equals the full 508 mm (20 in) turning length, and X travel is 200 mm (7.87 in). At that length a part is long enough to need support, and the table lists a hydraulic, programmable tailstock as optional. Anyone planning shaft work should establish whether the machine has it, because without it the usable length for slender parts is much shorter than the travel.
Rapid traverse is 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z on hardened and ground box ways. The 12-station VDI turret is listed as live tooling capable, the control is a Fanuc 0i-TF Plus, and the machine weighs 3,800 kg (8,378 lb).

Strengths & Limitations
Strengths
- Spindle torque of 175 Nm (129 ft-lb) with 15 kW (20 HP) continuous
- Turning envelope of 356 mm (14 in) diameter by 508 mm (20 in) length, with matching 508 mm (20 in) Z travel
- 16C collet-ready A2-6 spindle with collet TIR of 3 microns (0.00012 in) or better
- Hardened and ground box ways with rapids of 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z
- 12-station VDI turret listed as live tooling capable
Limitations
- The hydraulic, programmable tailstock is optional, so a given machine may not have one
- Spindle speed is limited to 5,000 RPM, which caps surface speed on small diameters
- No sub-spindle, C axis or driven-tool figures are listed
- Bar capacity is 51 mm (2 in); larger stock has to be chucked as cut blanks

Frequently Asked Questions
01
The listed figures show a hydraulic, programmable tailstock as optional. That means it was not part of every machine. With 508 mm (20 in) of turning length, a tailstock matters for slender shafts, so confirm on the individual machine whether it is fitted.
02
15 kW (20 HP) continuous and 175 Nm (129 ft-lb) of torque, with a maximum of 5,000 RPM and an A2-6 spindle nose. The spindle is listed as 16C collet-ready and the chuck as 8 inch (200 mm) hydraulic. Bar capacity is 51 mm (2 in).
03
Maximum turning diameter is 356 mm (14 in) and maximum turning length is 508 mm (20 in). X travel is 200 mm (7.87 in) and Z travel is 508 mm (20 in). No maximum part weight is listed, so for heavy chucked parts check the chuck and spindle limits in the machine manual.
04
The only accuracy row is collet TIR, given as 3 microns (0.00012 in) or better. Positioning accuracy and repeatability are not listed. On a used machine the condition of the box ways and spindle bearings decides what it holds today, so a test cut is the reliable check.
