Crankshaft Machining And Grinding Equipment | RA Power Solutions

Introduction:

In the world of engine rebuilding and maintenance, precision and quality are of utmost importance. One crucial aspect that directly affects an engine’s performance is the condition of its crankshaft. To ensure optimal functionality, crankshafts often require machining, grinding, and polishing.

In this blog post, we will delve into the realm of crankshaft machining equipment, exploring the significance of crankshaft grinding and polishing machines and highlighting the advanced solutions offered by RA Power Solutions.

RA Power Solutions has been extending on-site crankshaft repair services for the last forty years. The crankshaft grinding and crankshaft machining are done onsite without removing the crankshaft from the engine block. This reduces the downtime of the equipment and results in considerable saving as it does not require packing, or transportation of the crankshaft to the designated workshop and this is now outdated.

The clients who were availing the services of crankshaft repair companies based in Europe and the UK and spending large amounts now can undertake the repairs themselves by using crankshaft grinding and crankshaft polishing machines. Thus bringing down the cost of repair considerably.

Crankshaft Refurbishment

We think that whenever the engine is taken up for overhaul, the crankshaft should be calibrated and refurbishment should be done. In most cases, due to continuous running bearing line marks, pitting, and rough surface are observed on the crankpin and main journal diameter of the crankshaft. In this situation, it is advised that crankshaft refurbishment should be undertaken which may cover grinding and polishing of main journals and crank pin diameter as the situation may be.

Crankpin Grinding by Crankshaft Grinding Machine – RA Power Solutions

A diesel power plant based in northern India having 10 nos. of 12.3 MW Wartsila diesel generating sets reported severe causality involving one of their Wartsila generators.

RA Power Solutions team of technicians rushed to the power plant with the measuring instruments and onsite crankshaft grinding equipment to assess the cause of the breakdown.

On undertaking the detailed inspection of the crankshaft including dimensional check, hardness test, and MPI for crack and deflection, it was observed that one of the crankpin journals was damaged due to the failure of a big end bearing.

The following were the main observations:

  • Taper and ovality in the crankpin were observed as 0.70 mm.
  • Due to the failure of the bearing, deep line marks were visible.
  • Hardness and MPI tests were done, and no cracks were observed.

RA Power Solutions used the latest design of onsite crankshaft grinding machine having almost no vibrations. The crankpin was undersized by 1.5 mm maintaining the tolerance within 10 microns. Our technicians took only 18 hours to complete the Crankshaft repair from the time of the start of the preliminary inspection, grinding, and final inspection. The repair of the crankpin in such a short time was possible due to the latest technology onsite crankshaft grinding machine used and the experience of our technicians. The engine was assembled and is performing satisfactorily.
