Overview
The Hardinge Quest CHNC 42 SP is a twin-spindle collet lathe for 42 mm (1.65 in) bar. Both spindles run to 6,000 RPM, both have a C-axis, and the 12-station turret is listed as live tooling capable, so the listed figures describe a machine meant to finish both ends of a bar part without a second setup.
The two spindles are not equal. The main spindle has 11 kW (15 hp) and 120 Nm (88 ft-lb); the sub-spindle has 7.5 kW (10 hp), and no torque is given for it. Plan the heavy stock removal on the main side and leave the sub-spindle the back-face work: cleaning up the cut-off face, back boring, chamfers, light milling. Matching top speeds help the handover, since the part can be passed across with both spindles turning in step and without slowing the main spindle.
Workholding is collet-based. The spindle is listed as 5C/16C collet-ready with a direct seat, and concentricity is given as 2.5 microns TIR at the collet face. No chuck size appears in the table. Maximum turning diameter is 220 mm (8.66 in) and maximum turning length 350 mm (13.78 in), with 180 mm (7.09 in) of X travel and 400 mm (15.75 in) of Z.
The turret is listed as VDI/BMT, so check which interface a given machine carries, and check that driven holders are actually fitted, since capable is not the same as equipped. Hardened and ground box ways carry the axes at 20 m/min (787 ipm) in X and 24 m/min (945 ipm) in Z. The control is a Fanuc 0i-TF Plus and the machine weighs 3,800 kg (8,378 lb).

Strengths & Limitations
Strengths
- Main and sub-spindle both run to 6,000 RPM, so parts can be transferred at matched speed
- C-axis on both spindles, with a 12-station turret listed as live tooling capable
- 5C/16C collet-ready spindle with a direct seat and 2.5 microns TIR at the collet face
- 400 mm (15.75 in) of Z travel against a 350 mm (13.78 in) maximum turning length
Limitations
- The sub-spindle has 7.5 kW (10 hp) against 11 kW (15 hp) on the main spindle, and no torque is listed for it
- No Y-axis is listed, so off-centre milled features are limited to what C-axis and X can produce
- Bar capacity is 42 mm (1.65 in) and no chuck size is given
- The turret row reads VDI/BMT without saying which is fitted

Frequently Asked Questions
01
The sub-spindle is listed at 6,000 RPM and 7.5 kW (10 hp), with its own C-axis. It takes the part from the main spindle so the back end can be machined in the same cycle. It has less power than the 11 kW (15 hp) main spindle, so keep the second side light.
02
The collet system is listed as 5C/16C collet-ready with a direct seat. Bar capacity is 42 mm (1.65 in), and spindle concentricity is 2.5 microns TIR at the collet face. The table does not list a chuck.
03
The turret is listed as live tooling capable and both spindles have a C-axis, which together allow drilling and milling on either end of the part. No driven-tool speed or power is given and there is no Y-axis row, so confirm what driven holders the machine has.
04
The listed maximum turning diameter is 220 mm (8.66 in) and the maximum turning length 350 mm (13.78 in). X travel is 180 mm (7.09 in) and Z travel 400 mm (15.75 in). Through the spindle, bar is limited to 42 mm (1.65 in).
