Our best estimate for a cnc lathes / turning center in this class — not a quote from Leadwell. Configuration moves it a long way.
Overview
The Leadwell T-7i is a turning center with a 200 mm (8 in) chuck as standard, a maximum turning diameter of 380 mm (15.0 in) and a maximum turning length of 560 mm (22.0 in). The listed figures have not been confirmed against a Leadwell page, so check them against the documents of the machine being considered.
Three diameters describe the work envelope, and they mean different things. Swing over the bed is 480 mm (18.9 in), the largest part that clears the machine. Maximum turning diameter is 380 mm (15.0 in), the largest the tools can cut. Swing over the cross slide is 260 mm (10.2 in), the limit for a long part that has to pass above the slide. A short disc can use the full turning diameter; a shaft near the full 560 mm (22.0 in) length cannot.
Bar capacity is 65 mm (2.6 in) through an A2-6 spindle nose, so the machine can be bar-fed for parts up to that diameter. The spindle runs to 5,000 RPM on 15 kW (20 hp). No torque figure is listed, which leaves low-speed cutting on large diameters as a question for the spindle diagram.
The turret is a 12-station VDI 30. Live tooling at 4,000 RPM is listed as optional, so a machine without it is limited to turning, boring and threading on centre. Rapids are 15 m/min in X and 20 m/min in Z, the control is a Fanuc 0i-TF, and the weight is approx. 4,500 kg (9,921 lb).

Strengths & Limitations
Strengths
- Bar capacity of 65 mm (2.6 in) through an A2-6 spindle nose
- Maximum turning diameter of 380 mm (15.0 in) with a 480 mm (18.9 in) swing over the bed
- 12-station VDI 30 turret, with live tooling at 4,000 RPM available as an option
- 5,000 RPM spindle with 15 kW (20 hp)
- Rapid traverse of 15 m/min in X and 20 m/min in Z
Limitations
- Live tooling at 4,000 RPM is optional, not standard
- Swing over the cross slide is 260 mm (10.2 in), which limits the diameter of long shafts
- Maximum turning length is 560 mm (22.0 in)
- No spindle torque figure is listed, so heavy cuts on large diameters cannot be judged from the table

Frequently Asked Questions
01
Maximum turning diameter is 380 mm (15.0 in) and maximum turning length is 560 mm (22.0 in). Swing is 480 mm (18.9 in) over the bed and 260 mm (10.2 in) over the cross slide. The standard chuck is 200 mm (8 in). These are the listed figures and are unverified.
02
Only as an option. The live tool speed row gives 4,000 RPM and marks it optional, so milling, cross drilling and off-centre work depend on how a machine was ordered. The turret itself is a 12-station VDI 30. Check the turret and the option list of the specific machine.
03
Bar capacity is listed as 65 mm (2.6 in), with an A2-6 spindle nose. The spindle runs to 5,000 RPM and is rated 15 kW (20 hp). A bar feeder is not part of the listed figures, and the draw tube and chuck fitted can reduce the usable bore, so measure it.
04
The control is listed as a Fanuc 0i-TF. Rapid traverse is 15 m/min in X and 20 m/min in Z. The machine weighs approx. 4,500 kg (9,921 lb). The table gives no figures for power supply or floor space, so take those from the installation drawing.
