Description
The DL E Heavy 620/1500 is a heavy-duty conventional lathe engineered for machining large diameters and long workpieces. It handles parts up to 1,500 mm in length and turning diameters over the bed up to 1,250 mm. The wide, ribbed cast-iron bed supports heavy workpiece weights while a 22 kW main drive and a finely adjustable multi-disc clutch drive the spindle; the tailstock is motorized on extended-center models.
