Crankshaft grinding and crankshaft polishing are required not only in case of accidents but are also required to be undertaken after the engine has completed the designated number of hours of operation. It is generally observed that taper and ovality, rough surface on crankpin and main journal develop, which necessitates crankshaft grinding and crankshaft polishing, depending on the technical parameters observed after the inspection.

RA Power Solutions has been working on the crankshafts of medium and high capacity engines for more than four decades. We realized that a few companies based in Europe have made these services a monopoly business, and projected crankshaft grinding and crankshaft repair as a difficult task. They also charged an exorbitant amount from the shipping companies, diesel power plants, and companies having rotator equipment. RA Power Solutions Pvt. Ltd. developed an onsite crankshaft grinding machine, which is capable of undertaking the grinding of the crankshaft onsite without the removal of the crankshaft from the engine block. The crankshaft grinding and crankshaft repair tools is possible by inserting the portable and light-weight machine from the inspection window. We are presently manufacturing crankshaft grinding and repair machines having a range from 35 mm to 700 mm, which largely covers most of the popular makes and models of engine crankshafts.
