For satisfactory running and performance of a diesel engine or any rotary equipment, it is important that the crankshaft is periodically checked dimensionally and for other important parameters. For any correction and repair required in the crankpin and main journal diameter of the crankshaft, a crankshaft grinding and polishing machine is required. RA Power Solutions is into the field of repair of crankshaft repair for the last forty-five years.
Necessity for Onsite Crankshaft Grinding and Polishing Machine
It is observed that after continuous running of the engine and crankshaft, it is important that during the major overhaul of the engine crankshaft is inspected for the following main parameters:
- To check the taper and ovality of the crankpin/main journal diameter
- To check the surface finish of the crankpin/main journal
- Inspection of hardness and the presence of cracks
- Visual inspection for radius fillet and lubricating oil hole
In case of any deviation beyond the manufacturer’s limit is observed in the crankpin and main journal, crankshaft need grinding and polishing. Hence there is a requirement of crankshaft grinding machine which is capable of maintaining the tolerances as stipulated in the manufacturer’s manual.
Change of Technology – In situ Crankshaft Grinding & Polishing Machine
In olden times invariably bench-type crankshaft grinding machine was used. These machines were installed in a workshop, and it was necessary to disassemble the engine, remove the crankshaft, pack and transport it to the designated workshop. This is now outdated.
The technology change has taken place, the heavy-duty duty expensive bench-type crankshaft grinding machines are replaced by portable, lightweight, easy-to-operate in situ crankshaft grinding and polishing machines. There is no requirement for the removal of the crankshaft from the engine block, as the crankpin/main journal grinding and polishing can be done onsite. The machine is inserted from the inspection window.
Main Features of Revolutionary Onsite Crankshaft Grinding and Polishing Machine

Quality Aspect of In situ Crankshaft Grinding Machine
We are an ISO certified company, and all the quality control norms are strictly followed during the manufacturing of the machine.
Main body of the machine is manufactured out of titanium steel which has the inherent quality of absorbing the vibrations. This facilitates to undertake grinding and polishing of crankshaft even while sailing of the vessel. Every part is subject to stringent inspection and metallurgical properties are improved from time to time based on the field trails and reports.
In situ crankshaft grinding machine is priced low and is affordable for the shipping companies, power plants, and engine repair workshops. The cost of an in situ crankshaft grinding and polishing machine is recoverable in two or three assignments.
