The ST-15 offers 63.5 mm bar capacity and a maximum cutting capacity of 356 by 406 mm, with a swing of 406 mm over the cross-slide. It is equipped with a 210 mm hydraulic three-jaw chuck and a 12-station BOT turret.
The ST-15’s A2-6 spindle nose has an 88.9 mm bore, while the 15 kW vector dual-drive spindle turns to 4,000 rpm and provides 203 Nm of torque. On-the-fly wye-delta switching is said to yield a wide constant-horsepower band for constant surface feed cuts, which are supported by 30.5 m/min rapids and fast turret indexing.
Standard equipment includes rigid tapping, a 15-in colour LCD monitor and a USB port.
