| MACHINE DESCRIPTION | ||
| Description | CKD BLANSKO SKJ 25/50 CNC heavy-duty vertical lathe equipped with Siemens Sinumerik 802D CNC control. The machine provides a maximum turning diameter of 5,000 mm (196.85 in), maximum workpiece height of 2,000 mm (78.74 in) and maximum stated workpiece capacity of 40,000 kg (88,185 lbs). | |
| Faceplate & Workpiece Capacity | Equipped with a 2,500 mm (98.43 in) diameter faceplate with a stated rotational speed range of 1–100 rpm. The machine is designed to accommodate large and heavy components weighing up to 40 metric tons. | |
| Ram & Tool Head | The vertical ram provides 1,250 mm (49.21 in) of travel. The tool head offers ±30° tilting capability for machining operations requiring angular tool positioning. | |
| Drive System | Main drive power is 50 kW (approximately 67.05 HP), with the supplied specification stating a control range of 1:27.5 or 1:10 for constant cutting speed. Feed drive power is 4.2 kW (approximately 5.63 HP) with a stated control range of 1:400. | |
| Feed Capability | The stated feed range is 0.5–200 mm/min (0.020–7.874 in/min), or 0.03–20 mm/rev (0.0012–0.7874 in/rev). | |
| Machine Size | Overall machine height is approximately 6,800 mm (22.31 ft), with an approximate machine weight of 38 metric tons (83,776 lbs). | |
| Typical Applications | Suitable for heavy-duty vertical turning of large-diameter and high-weight industrial components where large workpiece capacity, high rigidity and controlled CNC machining are required. | |
