Description
The DL E Heavy 620/3000 is a conventional heavy-duty lathe designed for machining large diameters and long workpieces. It supports workpiece lengths up to 3,000 mm and turning diameters over the bed up to 1,250 mm. The heavily ribbed, wide machine bed and oversized components are engineered to carry high part weights while maintaining stability for heavy turning operations.
