In olden times, bench-type CNC crankshaft grinding machines were used for grinding of journals and crankpins of the crankshaft to remove the material and to refurbish them in case of accidents or wear and tear due to continuous running. The crankshaft of the medium and high capacity engines has an important role to play in transmission of power and for satisfactory performance of engine.
In this blog, we will compare the grinding and repair of crankshaft on a CNC bench-type crankshaft grinding machine installed in the workshop and onsite crankshaft grinding by a portable and easy to carry to any site all over the world crankshaft grinder, which is considered to be a revolutionary invention for crankshaft repair and crankshaft grinding.


DISADVANTAGES OF CNC CRANKSHAFT GRINDING MACHINE BENCH TYPE FOR REPAIR AND GRINDING OF CRANKSHAFT:-
- The main disadvantage of installing a CNC crankshaft grinding machine is that it needs a heavy workshop with all amenities.
- Technicians must remove the crankshaft from the engine block, pack it properly, and transport it to the workshop where the team has installed the crankshaft grinding machine.
- This whole exercise is not only expensive but also takes a lot of time.
- In case of ships, it is rather impossible to remove the crankshaft of the main and auxiliary engines and send it to the workshop.
- Workshops ideally use CNC crankshaft grinding machines today for production purposes. Manufacturers primarily use them to produce new crankshafts.
- High cost of the machine and the infrastructure required.
ADVANTAGE OF HAVING ONSITE PORTABLE CRANKSHAFT GRINDER:-
- The foremost advantage of an onsite portable crankshaft grinder is that the grinding machine can be taken to any site all over the world, including on vessels.
- Technicians do not need to remove the crankshaft from the engine block. Removing it usually requires the special attention of engine manufacturer engineers to disassemble the engine.
- While reassembling a crankshaft, technicians require several spare parts. These include packing, gaskets, and other components after removing the crankshaft from the engine block.
- The portable crankshaft grinder is inserted from the inspection window of engine block and grinding/polishing/machining as per the requirement is undertaken.
- The time taken for onsite crankshaft repair is minimum as there is no requirement of removing the crankshaft and transporting it to the designated workshop.
- The cost of using a portable crankshaft grinder is low.
MANUFACTURING, EXPORT, AND TRAINING OF ONSITE CRANKSHAFT GRINDER MACHINE:-
- RA Power Solutions, with 45 years of experience as a crankshaft grinder machine manufacturer and engine repair service provider, has introduced a portable crankshaft grinder. The machine is lightweight and technicians can easily take it to the site by air as accompanied baggage.
- The grinding and polishing of the same crankshaft grinder equipment is possible in one setting.
- The crankshaft grinder is easy to operate. We offer one week of free training to the client’s technician at our training school near New Delhi. Alternatively, we send our senior engineer to the client’s workshop for on-site training.
- Currently, manufacturers produce on-site crankshaft grinders in the range of 35 mm to 700 mm. We are developing a crankshaft grinder up to 1000 mm and will launch it in the international market shortly.
COST OF ONSITE CRANKSHAFT GRINDER MACHINE:-
- The cost of on-site crankshaft grinder machines is negligible.
- We have sold all over the world, insitu portable crankshaft grinding machines number exceeding 70.
- Our present clients come from shipping companies, power plants, and heavy industries. They use crankshafts and cylindrical grinders.
- Engine repair workshops using RA Power Solutions crankshaft grinding machines have challenged expensive European repair companies. These workshops have expanded. They generate high revenue.
