Crankshaft Grinding & Polishing Machine | Onsite Cylindrical Grinding Machine

Crankshaft is considered to be a heart of the engine. It is important that all the parameters recommended by engine manufacturers are strictly maintained for continuous and satisfactory performance of the engine.

It is observed that crankshaft failure can happen at any time in spite of excellent maintained engine. Secondly, due to continuous running of a diesel engine wear and tear, development of taper and ovality, pitting, and rough surface is developed. This needs to be corrected. By introduction of onsite crankshaft grinding and crankshaft polisher machine, RA Power Solutions has made onsite crankshaft grinding and polishing easy. Now there is no need of removing the crankshaft and sending it to the workshop for repairs.

  • The onsite crankshaft grinding and polishing is undertaken by the same equipment. Every time engine is open for major overhauling, crank pin and main journal of crankshaft can be polished to remove the bearing line marks and to improve the surface finish. This increases the life of bearing and avoids crankshaft from breakdown.
  • The crankshaft grinding and crankshaft polishing machine is designed to provide workshop quality service onsite, drydock or even while sailing of the vessel. The crankshaft grinding equipment has minimum vibrations, manufactured of titanium alloy which absorbs the vibrations. This facilitates to maintain close tolerances of crankpin and main journal of the crankshaft even while sailing of the vessel.
  • 24/7 global support services are provided for any guidance for operation and maintenance of the onsite crankshaft grinding machine. A training program is designed and arranged onsite covering all the aspects of the operation and maintenance of the machine.
  • Machine is priced low and has the capability to generate high revenue in a short time. The onsite crankshaft grinding machine is supplied complete in all respect and ready to operate with consumables sufficient to repair one crankshaft.

On-Site Crankshaft Grinding Machine | Crankshaft Polishing Machine

Crankshaft grinding machines are designed to maintain the accurate tolerances as per the engine manufacturer’s recommendation.

Generally, it is observed that even for the higher diameter of crankpin and main journal of the crankshaft the tolerances do not exceed more than 0.05mm in order to achieve such close tolerances of crankpin and main journal of crankshaft RA power designs and manufactures on-site crankshaft grinding machine which has the capability to maintain the close tolerance of even 0.01mm/0.02mm which is far better than the close tolerance specified by the engine manufacturers.

The on-site crankshaft grinding machine and crankshaft polishing machine manufactured by RA power solutions has the following features:

  • Crankshaft grinding machine is designed in a way that it can be inserted from the inspection window of the engine block thus there is no need of removal of the crankshaft from the engine block.
  • In case of space restrictions, RA power has the capability to design the equipment according to the space available on site for grinding or polishing of crankshaft/turbine/alternator shaft/rotor shaft etc…
  • The on-site crankshaft grinding machine is lightweight portable and can be easily carried to the site all over the world. The crankshaft grinding machine is packed in the suitcase and is carried as accompanied baggage accepted by all international airlines.
  • The main body of crankshaft grinding equipment is manufactured out of titanium alloy which is lightweight and can absorb the vibrations this feature of crankshaft grinding machine facilitates RA power technicians to undertake crankshaft repair on board the vessel while it is sailing, maintaining the close tolerances within 20 microns.
  • Crankshaft grinding machine designed and manufactured by RA power can presently work up to 700mm diameter which we are in process of extending up to 1000mm.
