Overview

The Okuma V40R is a chucking lathe for short, wide parts: 400 mm (15.75 in) maximum turning diameter, 450 mm (17.72 in) turning length and a 500 mm (19.69 in) maximum swing. The standard chuck is a 381 mm (15 in) hydraulic unit, nearly as large as the turning diameter itself, and a 457 mm (18 in) chuck is optional.

Okuma's table gives a torque figure for this model: 500 Nm (369 ft-lb), from a 22/18.5 kW (30/25 hp) spindle running 25 to 2,500 rpm. The two power ratings sit close together, so the lower one still leaves most of the headline power available for long cuts. Rapid traverse is 24 m/min (78.74 fpm).

The V760EX is the next size up, at 760 mm (29.92 in) turning diameter, 770 mm (30.31 in) turning length and 30/22 kW, with a lower 2,000 rpm top speed. The 2SP-V40 is listed with the same 400 mm diameter, 450 mm length, 500 mm swing and 22/18.5 kW as the V40R.

Strengths & Limitations

Strengths

500 Nm (369 ft-lb) of spindle torque from a 22/18.5 kW (30/25 hp) motor
381 mm (15 in) hydraulic chuck as standard, with a 457 mm (18 in) chuck optional
Spindle range of 25 to 2,500 rpm, above the 2,000 rpm of the larger V760EX
24 m/min (78.74 fpm) rapid traverse over a 450 mm (17.72 in) turning length

Limitations

Maximum turning diameter is 400 mm (15.75 in); the V760EX goes to 760 mm (29.92 in)
Turning length is 450 mm (17.72 in), so this is for disc and hub shapes, not shafts
The 457 mm (18 in) chuck is an option, not part of the base machine
No turret station count or tool size rows in Okuma's headline table

Best For

Disc, hub and flange parts up to 400 mm (15.75 in) in diameter Short chucked work within 450 mm (17.72 in) of turning length Roughing cuts that draw on the 500 Nm (369 ft-lb) spindle torque

Frequently Asked Questions

01 What size chuck does the V40R take?

The standard chuck is 381 mm (15 in), hydraulic. A 457 mm (18 in) chuck is listed as an option. Maximum turning diameter is 400 mm (15.75 in) and maximum swing is 500 mm (19.69 in), so check jaw and fixture clearance against the swing figure.

02 How much spindle power and torque does the V40R have?

The spindle is listed at 22/18.5 kW (30/25 hp) and 500 Nm (369 ft-lb), with a speed range of 25 to 2,500 rpm. Okuma's table gives the torque as a single figure and does not state the speed at which it is reached.

03 How does the V40R compare with the V760EX?

The V760EX is nearly twice the size: 760 mm (29.92 in) turning diameter, 770 mm (30.31 in) turning length and an 800 mm (31.50 in) swing, with 30/22 kW (40/30 hp). The V40R turns 400 mm (15.75 in) by 450 mm (17.72 in) with 22/18.5 kW (30/25 hp), and runs faster, 2,500 rpm against 2,000 rpm on the V760EX. Both rapid at 24 m/min (78.74 fpm).
