How much does the Victor Taichung Vturn-40/425 cost?
Price estimate
We do not have a price for the Victor Taichung Vturn-40/425 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
No lathe in Victor Taichung's current list turns a longer part on a Ø91 mm bore than the Vturn-40/425: 4,300 mm (169.29 in) between a 15 in chuck and an M.T. #5 centre. The spindle nose is A2-11, top speed is 2,500 rpm and bar capacity is Ø91 mm (Ø3.58 in).
It is a large installation. The 2 Axis machine weighs 22,000 kg (48,501.63 lb), the C Axis machine 22,300 kg (49,163.02 lb) and the Y Axis machine 22,500 kg (49,603.94 lb). The site has to take the bed in one piece, and the chip conveyor and its cart add to the length.
The usual three configurations are offered, with one difference from the shorter beds. The Y Axis column lists 10 turret tools here, where the other lengths list 12; the C Axis column still has 12 and the 2 Axis column 10. Maximum turning diameters are Ø620 mm (Ø24.4 in), Ø580 mm (Ø22.83 in) and Ø520 mm (Ø20.47 in) in that order. If the tool count matters for a Y Axis order, confirm it.
The machine is described by its maker as a heavy cutting lathe on a single-piece 45-degree slant bed. Shafts of this length cannot be turned without intermediate support, so the optional steady rest, manual or hydraulic, is effectively part of the machine. All tooling is on □32 mm shanks.

Strengths & Limitations
Strengths
- 4,300 mm (169.29 in) turning length, the longest of the Vturn-40 beds
- Ø620 mm (Ø24.4 in) maximum turning diameter as a 2 Axis machine
- Ø91 mm (Ø3.58 in) bar capacity through an A2-11 spindle
- C Axis and Y Axis configurations for milling on very long parts
Limitations
- Weighs 22,000 kg (48,501.63 lb) or more
- The Y Axis column lists only 10 turret tools on this length
- A steady rest is needed for most work and is an option
- With the Y axis, turning diameter is limited to Ø520 mm (Ø20.47 in)

Frequently Asked Questions
01
4,300 mm (169.29 in), with a maximum turning diameter of Ø620 mm (Ø24.4 in) on the 2 Axis machine. Victor Taichung gives the Vturn-40 range of turning lengths as 1250mm to 4250mm in its series notes.
02
The table lists 10 tools for the 2 Axis machine, 12 for the C Axis machine and 10 for the Y Axis machine, all on □32 mm shanks. The Y Axis figure differs from the shorter Vturn-40 beds, so confirm it when ordering.
03
22,000 kg (48,501.63 lb) as a 2 Axis machine, 22,300 kg (49,163.02 lb) with the C axis and 22,500 kg (49,603.94 lb) with the Y axis. Foundation work and heavy rigging are part of the project.
04
Yes, the option list for the series includes a steady rest in manual or hydraulic form. On a bed of this length it should be treated as required equipment for slender parts.
