Overview

The Okuma 2SP-150H is a small two-spindle chucking lathe built for loader-fed work. Chuck size is 6 in (150 mm), the main and sub spindle are each rated 11/7.5 kW (15/10 hp), and the speed range is 50–4,500 rpm.

The figure that decides what fits is the turning length. With the loader in place Okuma lists 80 mm (3.15 in); without it, 150 mm (5.91 in). The loader therefore takes almost half of the working length, and a part should be judged against 80 mm if the machine is to run unattended.

Main and sub spindle carry the same rating, so neither side of the part has to be given the lighter cuts. The spindle nose is 140 flat and rapid traverse is 24 m/min (945 ipm). For larger chuck work in the same two-spindle format, the 2SP-2500H lists a 410 mm (16.14 in) turning diameter and 200 mm (7.87 in) of turning length on a JIS A2-6 nose.

Strengths & Limitations

Strengths

Main and sub spindle are both rated 11/7.5 kW (15/10 hp), so first and second operations get equal power
Spindle speed range of 50–4,500 rpm with a 6 in (150 mm) chuck size
Rapid traverse of 24 m/min (945 ipm) keeps moves short on a machine with 80 mm (3.15 in) of turning length

Limitations

Turning length is 80 mm (3.15 in) with the loader; the 150 mm (5.91 in) figure applies only without it
The 6 in (150 mm) chuck size limits part diameter; the 2SP-2500H is the larger model, at 410 mm (16.14 in) of turning diameter
Okuma's headline table gives no maximum turning diameter and no turret details for this model

Best For

Short chucked parts within 80 mm (3.15 in) of turning length, fed by the loader Two-operation turning on spindles of equal 11/7.5 kW (15/10 hp) rating Small-diameter work held in a 6 in (150 mm) chuck

Frequently Asked Questions

01 What is the maximum turning length on the 2SP-150H?

It depends on the loader. Okuma lists 80 mm (3.15 in) of turning length with the loader and 150 mm (5.91 in) without it. For automated production the 80 mm figure is the one that applies, so measure the part and its chucking length against that.

02 Are the two spindles on the 2SP-150H the same?

In power, yes. The main spindle and the sub spindle are both listed at 11/7.5 kW (15/10 hp), and the table gives one speed range, 50–4,500 rpm, a 140 flat spindle nose and a 6 in (150 mm) chuck size.

03 How does the 2SP-150H compare with the 2SP-2500H?

The 2SP-150H is the small machine: a 6 in (150 mm) chuck size and 80 mm (3.15 in) of turning length with the loader. The 2SP-2500H lists a 410 mm (16.14 in) maximum turning diameter, 200 mm (7.87 in) of turning length and a JIS A2-6 spindle nose, with rapid traverse of 25 m/min (82 fpm) against 24 m/min (945 ipm) here.
