Hardinge Conquest T42SP vs Okuma 2SP-150H
Hardinge vs Okuma · CNC Lathes
Summary
The Hardinge Conquest T42SP and the Okuma 2SP-150H are both small-chuck CNC lathes, with a 165 mm (6.5 in) chuck on the Hardinge and a 6 in (150 mm) chuck on the Okuma, but they are laid out for different work. The Hardinge is a precision turning center for longer parts; the Okuma is a two-spindle machine for short chucked parts fed by a loader.
The Hardinge Conquest T42SP turns up to 305 mm (12 in) against 80 mm (3.15 in) on the Okuma, or 150 mm (5.91 in) without the loader. It also has the faster and stronger spindle: 6,000 RPM against 50–4,500 rpm, and 15 kW (20 hp) against 11/7.5 kW (15/10 hp). The Okuma rapids faster, 24 m/min (945 ipm) against 20 m/min (787 ipm).

Advantages
Hardinge Conquest T42SP
- 305 mm (12 in) turning length against 80 mm (3.15 in), or 150 mm (5.91 in) without the Okuma's loader
- 6,000 RPM spindle against 4,500 rpm
- 15 kW (20 hp) spindle against 11/7.5 kW (15/10 hp)
Okuma 2SP-150H
- Faster rapids: 24 m/min (945 ipm) against 20 m/min (787 ipm)
- Two spindles of equal rating for two-operation turning
- Loader-fed layout for short chucked parts
Verdict
Choose the Hardinge Conquest T42SP for precision turned parts such as fittings, bushings, valve spools and medical components, where 305 mm (12 in) of turning length, 6,000 RPM and 15 kW (20 hp) give room for longer work. Choose the Okuma 2SP-150H for volume runs of short chucked parts within 80 mm (3.15 in) that need both operations done in one machine, where its two spindles, loader and 24 m/min (945 ipm) rapids set the output.
