Overview

The Okuma VTM-1200YB turns parts up to 1,200 mm (49.21 in) in diameter and backs the turning table with a CAT 50 milling spindle, a Y axis and a B axis. Okuma's table lists three linear axes, X, Y and Z, and two rotary ones, C and B, so angled faces and holes can be machined in the same clamping as the turned surfaces.

X travel is 1,270 mm (50 in). Y is 1,000 mm (39.37 in), split 500 mm (19.69 in) either side of centre, and the bracketed option extends it to 1,240 mm, or 620 mm each way. Z is 1,080 mm (42.52 in) as standard and 1,530 mm (60.24 in) as the option, and the maximum cutting height is listed at 1,080 mm (42.52 in). X is longer than the turning diameter and Y covers most of it, so the milling spindle reaches nearly the whole top face with linear moves.

The milling spindle runs from 40 to 10,000 min⁻¹. A 50-taper spindle with that range carries large face mills and boring bars at the low end and still has the speed for smaller cutters, which is the mix a part of this size usually asks for. The turning table is listed at 30/22 kW (40/30 hp), with a speed range of 5 to 500 min⁻¹ and a bracketed 4 to 400 min⁻¹ variant; confirm which one a quoted machine carries.

Rapid traverse is 32 m/min (105 fpm) on X, Y and Z, with rotary rapids of 20 min⁻¹ on C and 19.5 min⁻¹ on B. In the VTM line this model sits between the VTM-80YB, which turns 800 mm (31.50 in) on 1,120 mm (44.09 in) of X, and the VTM-2000YB, which turns 2,000 mm (78.74 in) on 1,600 mm (62.99 in) of X at the same 32 m/min (105 fpm).

Strengths & Limitations

Strengths

CAT 50 milling spindle with a 40 to 10,000 min⁻¹ speed range
B axis as well as C, with listed rapid rates of 19.5 min⁻¹ and 20 min⁻¹, for angled holes and faces in one clamping
Y travel of 1,000 mm (39.37 in), or 1,240 mm with the bracketed option
Rapid traverse of 32 m/min (105 fpm) on X, Y and Z
Optional Z travel of 1,530 mm (60.24 in) in place of the standard 1,080 mm (42.52 in)

Limitations

Standard Y travel of 1,000 mm (39.37 in) is shorter than the 1,200 mm (49.21 in) turning diameter; covering the full width in Y needs the 1,240 mm option
The 1,530 mm (60.24 in) Z travel is an option; the standard machine has 1,080 mm (42.52 in)
Table speed tops out at 500 min⁻¹, or 400 min⁻¹ on the bracketed variant, which limits cutting speed on small turned diameters
Okuma's table gives no table load or tool magazine figure, so part weight and tool count need confirming

Best For

Turned parts up to 1,200 mm (49.21 in) that also need angled milling and drilling on a B axis Heavy milling with CAT 50 tooling in the turning setup Off-centre features within 1,000 mm (39.37 in) of Y travel Tall parts, with the optional 1,530 mm (60.24 in) Z travel

Frequently Asked Questions

01 What are the axis travels of the Okuma VTM-1200YB?

X is 1,270 mm (50 in). Y is 1,000 mm (39.37 in), running 500 mm (19.69 in) either side of centre, with a 1,240 mm option. Z is 1,080 mm (42.52 in), with a 1,530 mm (60.24 in) option. Rapid traverse on all three is 32 m/min (105 fpm).

02 What milling spindle does the VTM-1200YB have?

A CAT 50 spindle with a speed range of 40 to 10,000 min⁻¹. The 50-taper interface allows large face mills and long boring bars, and the top speed is high enough for smaller end mills and drills on the same part.

03 How fast does the turning table run?

Okuma lists a table speed range of 5 to 500 min⁻¹ and, in brackets, a 4 to 400 min⁻¹ variant. Table power is 30/22 kW (40/30 hp). Ask which speed range applies to the machine being quoted, because it sets the cutting speed available on small diameters.

04 Which rotary axes does the VTM-1200YB have?

The table lists both a C axis and a B axis, with rapid rates of 20 min⁻¹ and 19.5 min⁻¹. Together with X, Y and Z this lets the milling spindle approach the part at an angle, so inclined holes and faces do not need a separate setup.

05 How does it compare with the VTM-2000YB?

The VTM-2000YB turns 2,000 mm (78.74 in) with 1,600 mm (62.99 in) of X and 1,400 mm (55.12 in) of Z. The VTM-1200YB turns 1,200 mm (49.21 in) with 1,270 mm (50 in) of X and 1,080 mm (42.52 in) of Z as standard. Both list 32 m/min (105 fpm) rapids.
