The cost of on site crankshaft grinding machine is low and is used by shipping companies, power plants, oil and natural gas establishments etc all over the world.

With the change in  technology for repair of crankshaft, now it is possible to undertake the crank repair on site without dis assembly of the compressor, engine, forging equipment or any rotatory equipment. We manufacture crankshaft grinders which are portable and can be taken to the site for repair of the crankshaft. Our present range of manufacturing of crankshaft grinders is from 30 mm to 700. There is absolutely no requirement of removing the crankshaft from the compressor block and sending it to the workshop for repairs.

Our engineers are factory-trained and come to your plant and repair the crankshaft. Training on operation of crankshaft grinders manufactured by us is extended all over the world.

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.

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.

·         In case 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.

 

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.  

·         Presently, the onsite crankshaft grinders are manufactured in the range starting from 35 mm to 700 mm, we are working on the development of crankshaft grinder upto 1000 mm which will be launched in the international market shortly.

COST OF ONSITE CRANKSHAFT GRINDER MACHINE:-

·         The cost of onsite crankshaft grinder machines is negligible in comparison to the CNC bench type crankshaft grinding machines which are installed in the workshops.

·         We have sold all over the world insitu portable crankshaft grinding machines number exceeding 70.

·         Our present clients are from the field of shipping companies, power plants, heavy industries are using the crankshaft and cylindrical grinders.

We provide crankshaft grinder machines in countries like Australia, Bangladesh, Cambodia, Chinese Mainland, Hong Kong , Indonesia, etc

 

All the reciprocating equipments having crankshaft or different types of cylindrical shafts require grinding and polishing after continues running.

In case of heavy equipment, it is not practical to remove the shaft and send it to the workshop for repairs.  Infact, there are number of countries who do not have the facilities for inspection and machining of heavy duty shafts including engine crankshafts. The companies are left with only two options, one is to either reject the shaft and replace it with a new one or send the shaft to the third country for repairs. Both the options are not only expensive but are time consuming which no industry can afford.

Introduction of onsite machining and polishing machine by RA Power solutions:- 

RA Power Solutions has a background in working on engine crankshaft, rotor, alternator, turbine and cylindrical shafts repair for more than 41 years. During our service to the industry in remote places, we felt the necessity of designing, developing and manufacturing of onsite machining and polishing machine. Two decades back, we introduced the onsite crankshaft and cylindrical shaft grinding machines, we kept on improving the design, metallurgy and structure of the machine all these years.

We can confidently say that a crankshaft polishing tool or crankshaft polisher machine developed and manufactured by us is the best in terms of maintaining the tolerances in the world. 

Advantages of crankshaft polisher tool or machine:-

RA Power Solutions technicians boarded the vessel at JNPT Port, Mumbai India and undertook the inspection of the crankshaft.

 

Following was the main observation:

 

i) On visual inspection it was observed that crankpin bearing of CR no. 3  was damaged and bearing material was found in the sump.

 

ii) On removal of the connecting rod  it was observed the connecting rod bearing was badly struck on the crankpin and even the bearing material was embedded in crankpin diameter. 

 

iii) After removal of bearing material from crankpin circumference the inspection of crankpin was undertaken. 

 

iv)The crankpin dimension was observed as follows:

 a) Minimum diameter observed 269.43 mm.

 b) Maximum diameter observed 269.89 mm.

 

v) The hardness was checked and was observed within the limit.  

 

vi) The crack detection of Rolls Royce Engine crank pin was conducted by MPI method and no crack or abnormality was observed.

 

vii) On visual inspection of crank pin deep bearing line marks were observed. 

 

Action taken by RA Power Solutions to repair the crankshaft of Bergen Rolls Royce Engine.

 

i) The Grinding of crankpin no. 3 was undertaken to the step size of 1 mm. The final size after grinding was maintained as 269.00 mm. 

 

ii) After final grinding/ Polishing of crankpin all the parameters like taper, ovality, hardness, crack detection and surface test were undertaken and report on our standard format was prepared.  

We have been regularly executing the repairs in Argentina, Bahamas, Barbados, Bermuda, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Nicaragua etc.
