Overview

The Okuma 2SP-V40 is a two-spindle vertical lathe for chuck work up to 400 mm (15.75 in) in turning diameter, with a 500 mm (19.69 in) swing and 450 mm (17.72 in) of turning length. Spindle power is 22/18.5 kW (30/25 hp) and the speed range is 25–2,500 rpm.

A ceiling of 2,500 rpm and a floor of 25 rpm describe a machine set up for diameter, not for speed. Discs, hubs and rings in the upper part of the 400 mm range reach normal cutting speeds well below the top of that range, and a vertical spindle lets such parts settle into the chuck under their own weight. Two spindles in one machine can split a part into first and second operations or run one operation twice over; the headline table does not say how parts pass between them, so ask about the loader and turnover arrangement.

The V40R lists the same 400 mm turning diameter, 500 mm swing, 450 mm turning length and 22/18.5 kW, along with 500 Nm (369 ft-lb) of spindle torque and a 381 mm (15 in) hydraulic chuck with a 457 mm (18 in) option. Okuma's table for the 2SP-V40 itself has no torque or chuck row, so confirm both for the two-spindle machine. Rapid traverse is 24 m/min (78.74 fpm).

Strengths & Limitations

Strengths

Two vertical spindles with 22/18.5 kW (30/25 hp) of spindle power
400 mm (15.75 in) maximum turning diameter inside a 500 mm (19.69 in) swing
450 mm (17.72 in) of turning length, more than the turning diameter, so tall parts are not ruled out

Limitations

Spindle speed tops out at 2,500 rpm, which holds down surface speed on small diameters
Turning diameter stops at 400 mm (15.75 in); the 2SP-V760EX goes to 760 mm (29.92 in)
No chuck size or spindle torque is given in Okuma's headline table for this model

Best For

Disc, hub and ring parts up to 400 mm (15.75 in) in turning diameter Heavy chuck work that seats better on a vertical spindle First and second operations, or paired production, on two spindles

Frequently Asked Questions

01 What size parts does the 2SP-V40 handle?

Maximum turning diameter is 400 mm (15.75 in), maximum swing is 500 mm (19.69 in) and turning length is 450 mm (17.72 in). Chuck size is not in the headline table for this model, so the practical gripping range should be confirmed with Okuma.

02 How does the 2SP-V40 differ from the V40R?

The headline capacity figures match: the V40R also lists a 400 mm (15.75 in) turning diameter, a 500 mm (19.69 in) swing, 450 mm (17.72 in) of turning length and 22/18.5 kW (30/25 hp). The 2SP-V40 is listed with 2 spindles. The V40R table adds 500 Nm (369 ft-lb) of spindle torque and a 381 mm (15 in) hydraulic chuck, rows the 2SP-V40 table does not carry.

03 What is the spindle speed range of the 2SP-V40?

25–2,500 rpm, with spindle power of 22/18.5 kW (30/25 hp). The range suits large diameters. Small bores and faces near the center of a part will run below their ideal surface speed at 2,500 rpm, which is normal for a vertical lathe of this size.
