Crankshaft Grinding Machine | Crankshaft Grinder | Global Onsite Repairs – RA Power Solutions

Engine population is rapidly increasing for the shipping industry, power plants, and various applications. In most cases, engines are used not only for emergency purposes but as a base load. The continuous running of the diesel engine results in wear and tear of the crankpin and main journal of the crankshaft. In certain cases, taper and ovality more than the permissible limit are developed in the crankpin and the crankshaft main journal.

Inspection of Engine Before Grinding — **Inspection of the Engine Before Grinding**

The disassembly of the crankshaft from the main engine and sending it to the designated workshop is a lengthy process. This is now outdated. RA Power Solutions, having the experience of more than four decades in the repair of crankshafts, has developed a portable, lightweight engine crankshaft grinding machine and an onsite crankshaft grinding machine, which can be taken to the site as accompanying baggage. The onsite crankshaft grinding machine has the following features:

Lightweight can be carried to the site easily.
The portable nature of the onsite crankshaft grinding machine facilitates its insertion from the inspection window and allows for grinding and polishing of the crankpin.
The machine is designed can maintain the taper and ovality within 0.02 mm. This meets with the OEM’s tolerances.
Surface finish and other parameters can be maintained as per international norms.
The onsite crankshaft grinding machine is easy to operate
On-site training is provided for the smooth running of the crankshaft grinding machine.
More than 70 machines have been sold all over the world and are performing satisfactorily.

Crankshaft Grinding Executed on Board a Vessel – RA Power Solutions

RA Power Solutions has executed successfully the crankshaft grinding of 6 pins on board a vessel at Dumai/Lubuk Gaung Port, Indonesia of MAN B&W STX 6L23/30H Engine.

In this case, crankshaft grinding was required because all the CR pins, having a standard diameter of 185 mm, developed taper and ovality. Out of 6 CR pins, not even a single pin was seized, nor was a crack developed.

**Crankshaft Deflection and MPI Test Under Process**

The above observations show that the engine users should periodically get the crankshaft calibrated and go for grinding and polishing as the crankshaft develops taper and ovality due to continuous running.

To execute the above job, RA Power Solutions Pvt. Ltd. used a lightweight crankshaft grinder, which is lightweight, and the crankshaft grinder was taken to the site. RA Power Solutions has sold more than 60 crankshaft grinding machines all over the world.
