We have been working in the field of on site grinding of crankshaft services, Onsite machining, crankshaft machining, crankshaft reconditioning, crankpin reconditioning, marine crankshaft repair for almost four decades. Our engineers are trained in crankshaft grinding services, crankshaft repair, crank shaft forging and crank shaft machining facilities based in Europe and U.S.A. We have the necessary expertise and experience to handle any nature of problem related to the crank shaft grinding and repair.
Onsite Grinding of Crankshaft saves down time, cost and also eliminates the risk factors involved in transportation and handling of Crankshaft.
Insitu Grinding of Crankshaft services are provided by our trained and experienced technicians.
We undertake crankshaft repair and crankshaft grinding onsite without removing the crankshafts from the diesel engine. This process of onsite crankshaft grinding is getting popular as sending a crankshaft to workshop is outdated.
Crankshaft grinding and crankshaft polishing services are extended by RA Power Solutions all over the world for the engines installed on board the vessel, power plants, and in industry.
Crankshaft grinding services are offered for the crankpin and main journal diameter ranging from 60 mm to 700 mm. Crankshaft grinding services are provided onsite without removing the crankshaft from the engine block.
RA Power Solutions has experience of four decades and have trained technicians to execute crankshaft grinding services.
We have latest design of onsite crankshaft grinding machine, well trained and experienced technicians who are expert in attending to any problem related to high capacity Diesel engine, crankshaft grinding and crankshaft repair.
In situ Crankshaft Grinding Services are availed by leading Marine and Industrial Companies spread all over the world.
On site Inspection of crank shaft with appropriate Non Destructive Tests including hardness checking with portable hardness testing equipment, crack detection by Magnetic Particle Test (MPT). The Inspection Reports are prepared.
New generation in on site Crankshaft Grinding equipments can machine and polish in one setting itself as there is no need of separate tools for grinding and machining of Crank Pin and Main Journal of Crankshaft.
Onsite Crankshaft Grinding Equipment drastically reduces the set up time & minimizes the possibility of misalignment of Crank shaft & avoiding the need to set it up 2 or 3 times.
We can under take in situ Crank shaft grinding from CR Pin dia of 50 mm upwards. Special purpose tooling can be designed in case of limitation of working space in engine block.
In situ Straightening of Crankshaft is undertaken by pining process, this in situ Crankshaft Repair saves Crankshaft from rejection. Technicians are specially trained for on site repair of Crankshaft.
Trained, experienced engineers and mechanics skilled in the art of insitu crankshaft grinding execute the in situ repair of Crankshaft.
Ready availability of tools and specifications for most engines to execute in situ crankshaft grinding.
On site Polishing and Grinding of Crankshaft to remove Bearing line marks and Water marks.
We take pride in accomplishing grinding of over 10,000 Crankshafts in India and abroad which includes insitu crankshaft grinding and crankshaft repair in our workshop.
In Situ Repair of Crankshaft is under taken for following:
Main engine Crankshafts
Auxiliary engine Crankshafts
Cylindrical Shaft and rotating shaft of mechanical equipments
Tolerance of CR Pin and Main Journal of Crankshaft is maintained strictly as per OEM Specifications.
Technician accompany with senior engineer to plan and execute the job of Crankshaft Repair onsite.
Portable testing instruments of latest technology used for on site inspection of Crankshaft which covers Hardness check, magnetic particle test, deflection of crankshaft, dimensional inspection of CR and Main Journal of Crankshaft On site.
In situ Grinding of Crank Pin & Main Journal of Crankshaft under taken
Reconditioning of Crankshaft on site under taken of all make and model of marine, main and auxiliary engine.
Grinding of Large Crank Pin & Main Journal dia of Crankshaft:
In case of large diameter of Crankshaft, bearing width and high stock removal from the CR Pin, we suggest use of in situ grinding equipment which is placed on the fillet radius of the Pin as reference for the grinding stone.
The in situ Crankshaft Grinding machine rotates around the Crank Pin at lower RPM, the grinding is carried out by pneumatic grinder operating with suitable grinding stone. This process of Reconditioning of Crankshaft is recommended only if radius profile is not worn out.
