Used Stanko Sedin Vertical Turning Lathes
Stanko Sedin, the Krasnodar machine-tool plant, built some of the largest double-column vertical turning lathes in the Soviet bloc. The 1L532, with a 3200 mm swing, 2800 mm faceplate and 16-tonne workpiece capacity, ran in turbine plants, shipyards, railway works and defence facilities across Eastern Europe. TRIGA sources 1L532 and related Stanko Sedin VTLs from Polish heavy industry, with full documentation, on-site inspection and worldwide export support.
About Stanko Sedin
Also known simply as Sedin (Седин), the plant built the 1L-series of double-column vertical turning lathes described below.
The 1L532 is the Stanko Sedin machine that appears most on the European used market. Two cast columns carry a horizontal cross-rail supporting the turning and boring head. Swing diameter is 3200 mm, faceplate 2800 mm, turning height 1600 mm, maximum workpiece weight 16 tonnes, machine weight approximately 43 tonnes. The main drive motor is 55 kW. With 18 spindle speeds from 1.25 to 63 rpm, the 1L532 handles rough turning, finish turning, facing and boring of large rotating parts.
The 1L-series is mechanically straightforward: cast iron frames, conventional gearboxes, electromechanical controls. A competent millwright can overhaul a 1L532 without specialist factory support. Spare parts — gibs, bearing sets, toolholder components — come from Eastern European machine-tool suppliers. Machines maintained in operating condition give a buyer genuine large-swing capacity at far less than the cost of new equivalent equipment.
Stanko Sedin 1L532 machines were standard equipment in Polish heavy engineering plants: turbine and power station component works, shipyard shops, railway repair facilities and military-industrial enterprises. These machines now appear on the used market. TRIGA inspects each unit at source, documents faceplate, spindle, gearbox, cross-rail and slide condition, and handles dismantling, loading and export.

What to Check When Buying a Used Stanko Sedin 1L532
Faceplate run-out and spindle condition
Measure radial and axial run-out at the faceplate outer edge and at a test mandrel in the spindle. The 1L532 spindle runs in large tapered roller bearings; worn bearings produce run-out above 0.05–0.08 mm and audible noise at higher speeds. Spindle bearing replacement is a major job on a 43-tonne machine.
Cross-rail saddle and vertical slide
Check gib clearance on the cross-rail and both vertical slides. Worn gibs allow chatter and reduce surface finish quality. Inspect for scoring or fretting on the guide surfaces; repairable, but each defect adds to reconditioning cost.
Gearbox and spindle speed range
Engage all 18 spindle speeds and confirm smooth engagement with no abnormal noise. Soviet-era gearboxes are robust, but years of heavy use wear bearings and gears in the speed ranges run most often. Check that the lubrication system is functional and oil is clean.
Electrical system and controls
Check the 55 kW main drive motor, contactor condition and relay logic. Soviet electrics from the 1970s–1990s work, but relay and contactor spares require sourcing from Eastern European suppliers. Confirm all interlocks and feed drives operate.
Column geometry and levelness
Check column verticality with a precision level. On a 43-tonne machine that has been moved, column geometry shifts. Misaligned columns affect parallelism and squareness of every machined surface; correction requires shimming the base and re-tramming.
FAQ
Frequently Asked Questions
The 1L532 turns, faces and bores large-diameter heavy workpieces: turbine casings, large flanges, wheel and axle blanks, gear rings, bearing races, pump and compressor bodies. The 3200 mm swing and 16-tonne workpiece capacity put it in the heavy engineering category: shipbuilding, energy, railway and defence.
1L532 is the Soviet GOST designation: "1" denotes the lathe class, "L" the lathe family within the Stanko Sedin range, and "532" encodes the swing diameter in the 3200 mm range. Related models follow the same pattern: 1L516 (1600 mm swing), 1L550 (5000 mm).
The plant was in Krasnodar, southern Russia. It supplied heavy engineering enterprises across the USSR and Eastern Europe from the 1960s through the 1990s.
TRIGA sells machines as found and does not supply spare parts. Standard wear parts — gibs, bearing sets, toolholders — can be sourced from Eastern European machine-tool suppliers or machined to print. Manuals and foundation drawings are included where present.
The 1L532 weighs approximately 43 tonnes. Transport requires separating major assemblies — cross-rail, columns, faceplate/table unit — protecting all machined surfaces and crane-loading onto a low-loader or flat-rack container. TRIGA coordinates dismantling, loading, export paperwork and international shipping from Poland.
