In olden times, bench type CNC crankshaft grinding machines were used for grinding of journals and crankpins of 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 CNC bench type crankshaft grinding machine installed in the workshop and onsite crankshaft grinding by 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.
DISADVANTAGE 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.
The crankshaft is to be removed from the engine block, properly packed and transported to the workshop where the crankshaft grinding machine is installed.
This whole exercise is not only expensive but takes a lot of time.
Incase of ships, it is rather impossible to remove the crankshaft of the main and auxiliary engine and send it to the workshop.
ADVANTAGE OF HAVING ONSITE PORTABLE CRANKSHAFT GRINDER:-The main and foremost advantage of onsite portable crankshaft grinder is that the grinding machine can be taken to any site all over the world including on vessels.
There is absolutely no requirement of removal of the crankshaft from the engine block which requires special attention of engine manufacturer engineers to disassemble the engine.
While reassembling a crankshaft number of spare parts specially packing, gasket and various other spare parts are required once the crankshaft is removed 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.
MANUFACTURING, EXPORT AND TRAINING OF ONSITE CRANKSHAFT GRINDER MACHINE:RA Power Solutions with 41 years of experience in extending engine repair services including repair of crankshaft have introduced the portable crankshaft grinder which is light-weight and can be taken to the site easily as an accompanied Babbage by air.
The grinding and polishing from the same crankshaft grinder equipment is possible in one setting.
The crankshaft grinder is easy to operate and we extend one week free training to our client technician in our training school based near New Delhi or send our senior engineer to the clientÃ¢â¬â¢s workshop and country to extend the training.
Presently, the onsite crankshaft grinders are manufactured in the range starting from 35mm to 700 mm, we are working on the development of crankshaft grinder upto1000 mm which will be launched in the international market shortly.
