How much does the Hardinge Quest 6/42 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
With a 6 in (152 mm) chuck and 42 mm (1.65 in) of bar capacity, the Hardinge Quest 6/42 is a turning center that can be run either as a chucker or as a bar machine. The spindle bore is 42 mm (1.65 in), the same as the bar capacity, and the listed envelope is 220 mm (8.66 in) in maximum turning diameter by 350 mm (13.78 in) in maximum turning length.
The spindle is set up for speed with reasonable pull: 6,000 RPM, 11 kW (15 hp) and a maximum torque of 120 Nm (88 ft-lb). For a 6 in chuck that covers most steel and stainless turning at sensible depths of cut, and 6,000 RPM keeps surface speed up on bar well below the 42 mm limit. Spindle concentricity is listed as 2.5 microns TIR at the collet face, which counts most when parts are finished in collets and runout between bore and outside diameter is on the drawing.
Tooling is a 12-station turret listed as VDI/BMT. Those are two different tool-holder interfaces and holders do not interchange between them, so find out which one a particular machine has before buying or borrowing tooling. Live tooling is optional, and the table has no C-axis, sub-spindle or tailstock row.
X travel is 165 mm (6.50 in) and Z travel 350 mm (13.78 in), 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 listed control is a Fanuc 0i-TF Plus. Machine weight is 3,200 kg (7,055 lb).

Strengths & Limitations
Strengths
- Works from a 6 in (152 mm) chuck or from bar up to 42 mm (1.65 in) through a 42 mm (1.65 in) spindle bore
- 6,000 RPM spindle with 11 kW (15 hp) and up to 120 Nm (88 ft-lb)
- Spindle concentricity of 2.5 microns TIR at the collet face
- 12 turret stations on a 3,200 kg (7,055 lb) box-way machine
Limitations
- Live tooling is an option, and no C-axis is listed
- The turret is listed as VDI/BMT without saying which interface is fitted, so tooling cannot be planned from the table alone
- Maximum turning length is 350 mm (13.78 in), with no tailstock in the listed figures

Frequently Asked Questions
01
Yes, going by the listed figures. Bar up to 42 mm (1.65 in) passes through the 42 mm (1.65 in) spindle bore, and a 6 in (152 mm) chuck is listed for larger blanks, up to a maximum turning diameter of 220 mm (8.66 in).
02
The table says 12 stations, VDI/BMT, which reads as two possible interfaces and does not say which one a given machine carries. The two systems use different holders, so identify the turret on the actual machine before ordering tooling.
03
Maximum speed is 6,000 RPM, power is 11 kW (15 hp) and maximum torque is 120 Nm (88 ft-lb). Concentricity is listed as 2.5 microns TIR at the collet face. The table does not state the duty rating of the power figure or the speed at which torque peaks.
04
Only as an option. The live tooling row reads optional, and there is no C-axis row or driven-tool speed in the listed figures. A machine without the option is an X and Z lathe with 165 mm (6.50 in) and 350 mm (13.78 in) of travel.
