RA Power Solutions designs and manufactures crankshaft machining and polishing equipment having range from 35 mm to 700 mm in diameter. The crankshaft grinding machine is lightweight, easy to operate and portable equipment which can be taken to the site. The main feature of in situ crankshaft grinding machine is that there is no necessity of removing the crankshaft from the engine block or casing.
Cylindrical shafts up to 700 mm diameter can be grind and polished onsite irrespective of its application like compressor shaft, pump shaft, rotor shaft, alternator shaft, turbine, tail shaft, etc. In case of Auxiliary engine and main engine, it is observed that due to main journal or connecting rod bearing failure the journal diameter gets damaged having following broad discrepancies:
- Development of excessive taper and ovality beyond the permissible limit on crankpin and main journal diameter of the crankshaft.
- Bearing material getting embedded on the crankpin or main journal surface.
- Deep scoring marks or dents on the diameter and fillet radius.
- Variation in hardness due to generation of heat.
- Development of cracks.
In case of above defects developed in the crankpin or main journal of the crankshaft, it is necessary to undertake the grinding and polishing of crankshaft. In olden days, it was necessary to remove the crankshaft/cylindrical shaft from the casing, pack it and send it to the designated workshop for the repairs. This use to workout time consuming and expensive.
With the introduction of crankshaft grinding machine, the repair of the crankshaft has become simple. The crankshaft machining and polishing equipment is taken to the site of the installation of engine whether it is on land or off-shore. The grinding and polishing is undertaken without disassembly of the main equipment. We are expertise in crankpin grinding and polishing, along with their commitment to quality, makes them a preferred choice for clients seeking optimal engine performance and extended crankshaft life.
Crankshaft grinding machine manufacture by RA Power Solutions is capable of maintaining all the parameters of crankpin and main journal as per the manufacturer’s tolerance stipulated in the manual.
RA Power Solutions specializes in crankshaft repair of small diameter using advanced crankpin grinding and polishing techniques. Crankshafts are vital components in engines, and over time, they can develop wear, damage, or misalignment in the crankpins, resulting in reduced performance and efficiency. To address these issues, RA Power Solutions employs a precise and efficient process of crankpin grinding and polishing.
