Overview

The Hardinge Conquest T51 SP is a twin-spindle turning center with live tooling, sized around a 51 mm (2 in) bar and an 8 inch (200 mm) hydraulic chuck. The listed figures give a maximum turning diameter of 356 mm (14 in) and a maximum turning length of 508 mm (20 in), with X travel of 200 mm (7.87 in) and Z travel of 508 mm (20 in).

Both spindles run to 5,000 RPM, but they are not equals. The main spindle is listed at 15 kW (20 HP) continuous and 175 Nm (129 ft-lb) on an A2-6 nose, while the sub-spindle has 7.5 kW (10 HP), half the power. That split suits the usual division of labour: rough and finish the first side on the main spindle, hand the part over, and leave the lighter back-end cuts to the sub-spindle. C-axis is listed for both spindles, and the 12-station VDI turret drives live tools at 5,000 RPM, so cross holes, flats and keyways can go on either end of the part.

The slides run on hardened and ground box ways, with rapids of 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z. The spindle is 16C collet-ready, and collet runout is listed as 3 microns (0.00012 in) or better, the figure to weigh for bar work that needs diameters concentric to each other.

The control is listed as a Fanuc 0i-TF Plus and the machine weighs 4,300 kg (9,480 lb). No Y-axis, tool-size or sub-spindle torque rows appear in the table. Treat the listed figures as a guide and confirm them against the build sheet of the machine in front of you.

Strengths & Limitations

Strengths

Main and sub-spindle are both listed at 5,000 RPM with C-axis on each, so both ends of a part can be turned and milled in one cycle
12-station VDI turret with live tooling at 5,000 RPM
16C collet-ready spindle with collet runout listed as 3 microns (0.00012 in) or better
Main spindle listed at 15 kW (20 HP) continuous and 175 Nm (129 ft-lb) on an A2-6 nose
Hardened and ground box ways on a 4,300 kg (9,480 lb) machine

Limitations

The sub-spindle is listed at 7.5 kW (10 HP), half the main spindle's 15 kW (20 HP), so heavy cuts belong in the first operation
Bar capacity stops at 51 mm (2 in); larger stock has to be loaded as cut blanks in the 8 inch (200 mm) chuck
No Y-axis appears in the listed figures, so plan off-centre features around C-axis and X interpolation
Rapids of 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z are modest, the usual trade for box ways

Best For

Bar-fed parts up to 51 mm (2 in) finished on both ends in one cycle Turned parts needing cross holes, flats or keyways from live tools at 5,000 RPM Collet work where 3 microns (0.00012 in) or better runout matters Chucked parts within 356 mm (14 in) diameter and 508 mm (20 in) length

Frequently Asked Questions

01 Does the Conquest T51 SP have a sub-spindle?

Yes. The listed figures include a sub-spindle running to 5,000 RPM with 7.5 kW (10 HP), alongside a main spindle of 5,000 RPM and 15 kW (20 HP) continuous. C-axis is listed for both the main and the sub-spindle, so milled features can be indexed on either end of the part.

02 What bar size and part size can the Conquest T51 SP take?

Bar capacity is listed as 51 mm (2 in) through an A2-6 spindle nose, and the spindle is 16C collet-ready. For chucked work the 8 inch (200 mm) hydraulic chuck sits in an envelope of 356 mm (14 in) maximum turning diameter and 508 mm (20 in) maximum turning length.

03 Does the Conquest T51 SP have live tooling?

The turret is listed as a 12-station VDI with live tooling, and live tool speed is 5,000 RPM. With C-axis on both spindles that covers drilling, tapping and light milling on the face and the diameter. The table gives no live-tool power or torque, so ask for those before planning heavy milling.

04 What control and guideways does the Conquest T51 SP use?

The control is listed as a Fanuc 0i-TF Plus. The axes run on hardened and ground box ways, with rapid traverse of 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z. Machine weight is listed as 4,300 kg (9,480 lb), which matters for floor loading and rigging.
