Used UMARO Vertical Turning Lathes
UMARO, manufactured by Întreprinderea Mecanică Roman (I.M. ROMAN) in Roman, Romania, produced heavy double-column vertical turning lathes for Eastern Bloc heavy industry. The SC-series covers swing diameters from 1700 mm to over 4000 mm, built for turning, facing and boring large-diameter workpieces in energy, shipbuilding and heavy engineering plants. Later and CNC-retrofitted machines appear under the Titan-Umaro name. TRIGA sources and inspects UMARO VTLs from Polish and Central European industrial facilities, with full documentation and worldwide export support.
About UMARO / I.M. ROMAN
For buyers comparing UMARO listings, the SC number is the practical capacity marker: SC 17 machines are 1700 mm class VTLs, SC 43 reaches 4300 mm swing, and SCM 63/100 is the large-table version with an 8000 mm chuck.
SC-series machines use double-column construction: two cast columns carry a horizontal cross-rail supporting the tool slide, giving the rigidity needed for facing and boring heavy workpieces — turbine casings, flanges, gear blanks, bearing races, pump bodies — that a horizontal lathe cannot handle. The SC 17 CC (CC for two columns) has a 1700 mm swing, 1450 mm faceplate, 1200 mm turning height, 55 kW main drive motor and an 8000 kg workpiece capacity.
Later UMARO machines, including CNC-retrofitted examples with Siemens Sinumerik 840D or FANUC 0i controls, appear on the market as Titan-Umaro. The mechanical base is unchanged; Titan-Umaro indicates a control retrofit replacing the original manual or basic NC system. TRIGA evaluates these machines on spindle and geometry condition; the CNC generation is noted but does not substitute for a mechanical check.
UMARO machines turn up across Eastern and Central Europe, including Poland, where state-owned heavy engineering plants ran them for decades. As those plants close or modernise, SC-series VTLs enter the used market. Request available manuals, foundation drawings and electrical diagrams before purchase; TRIGA identifies and includes these with each sale where present.

What to Check When Buying a Used UMARO VTL
Faceplate run-out
Measure radial and axial run-out on the faceplate with a dial indicator. Run-out above 0.05 mm at the working diameter points to spindle bearing wear or a distorted table, both of which need reconditioning.
Cross-rail and saddle gibs
Check gib clearance on the cross-rail and the vertical saddle. Worn gibs produce vibration and surface-finish defects that tool adjustments cannot fix. Gib adjustment is routine maintenance; full replacement on a large machine takes time.
Spindle bearings
Run the spindle at low, medium and high speeds and listen for bearing noise. Check for thermal drift after 30 minutes at working speed. Spindle bearing replacement on a large double-column VTL is a major rebuild. Factor it into the offer price if you hear noise or measure drift.
Main drive motor and gearbox
On the SC 17 CC: check brush wear, armature insulation resistance and cooling on the 55 kW DC motor. Inspect the gearbox for oil leaks and confirm all speed ranges engage smoothly. Replacement DC motors of this size have long lead times.
Column and cross-rail geometry
Check column verticality and cross-rail levelness with a precision level. Misalignment affects parallelism and squareness of every turned surface. Correction on a large machine requires shimming the base and re-tramming.
FAQ
Frequently Asked Questions
The SC 17 CC turns, faces and bores large-diameter cylindrical workpieces: flanges, wheel hubs, gear blanks, bearing races, valve bodies and turbine components. The 1650 mm maximum turning diameter and 8000 kg workpiece capacity put it in the heavy engineering and repair-shop category.
UMARO lathes were built by Întreprinderea Mecanică Roman (I.M. ROMAN) in Roman, Neamț County, Romania. Romania was an Eastern Bloc country, not part of the Soviet Union. Its factories produced heavy machine tools for domestic industry and for export within the bloc.
Titan-Umaro designates later and CNC-retrofitted UMARO machines. The mechanical base — columns, cross-rail, faceplate and drive — is unchanged. The Titan-Umaro name indicates a control retrofit, typically Siemens Sinumerik 840D or FANUC 0i, replacing the original manual or basic NC control.
TRIGA sells machines as found and does not supply spare parts. Standard wear items — gibs, bearing sets, toolholder components — can be sourced from Eastern European machine-tool suppliers or machined to specification. For Titan-Umaro machines, control spares follow the relevant Siemens or FANUC parts programme.
Yes. On-site inspection is available. A static geometric check can be arranged; a cutting trial depends on whether the machine is installed and powered. Contact TRIGA to schedule a visit or request a remote video review.
