Heavy-duty Turning Lathes

Turning Lathes Type ENW 1600-2400

Turning Lathes Type ENW 1600–2400

Application:Line of universal turning lathes, which are suitable for boring of swing work pieces, for example, external cylindrical surfaces, internal holes, taper and thread machining.

Design features

Fitted with three guide ways, providing bigger loading capacity, strong rigidity and high accuracy
Main DC drive with digital control, 3 grades of mechanical or hydraulic speed change, spindle speed range can achieve 1:200
Feed driving is connected to the main driving, this allows increasing carriage travel and thread chaser
Tailstock built-in rotating center increasing loading capacity, 2 grade manual traversing function, and motorized tailstock traversing make operation easier
Usage of high-accuracy bearings with double-row short cylinder rollers in spindle bearing allow regulating radial clearance
