Onsite Grinding and repair of turbine shafts, rotor shafts, crankshafts, pump shafts, and alternator journals is undertaken.
Equipment is available to execute on site repair of turbine, crankshaft, rotor, and alternator journals up to a diameter of 700 mm, and can be extended up to 1500 mm in diameter.
Tolerance in terms of taper and Ovality is maintained within 20 microns of the turbine, crankshaft, rotor shaft, and alternator shaft, resulting in the minimization of vibrations.
Surface finish in terms of RA value maintained within 0.30 microns after on site repair of Turbine Shaft, Alternator Journal, rotor shaft, etc.
On site inspection facilities for crack detection, hardness, and surface finish tests.
Facility for rebabbitting and manufacturing white metal babbitt bearings.

Onsite repair jobs were executed. More than 100 jobs have been successfully executed for onsite repair of turbine shafts, rotor shafts, and alternator journals without removal.

Recently, we have executed an in situ repair of the turbine journal with the following major specifications:
