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.

Crankshaft Grinding Machine for Small Diameter – RA Power Solutions

The Introduction of Onsite Crankshaft Grinding Machine, Insitu Crankshaft Polishing and Grinding Machine, and Crankshaft Machining, there is no need of removing the Crankshaft and sending it to the work shop as now it is possible to undertake crankshaft grinding and crankshaft repair with revolutionary design of Onsite Crankshaft Grinding Machines manufactured by RA Power solutions.

Onsite grinding of crankshaft without removing it from the engine block is undertaken by taking the reference of radius fillet.

The onsite crankshaft grinding machine is placed on both side of the radius of the crankpin and tool rotates undertaking grinding and polishing of crankshaft. This process of crankshaft grinding by insitu crankshaft grinding machine is successful generally for the diameter of the crankpin of 200 mm and above having a bearing width of 125 mm minimum.

Crankshaft Grinding Equipment from 30 mm Diameter

For the smaller diameter of the crankpin, it is not possible to undertake the grinding by taking the reference of radius fillet due to the space constraints.

RA Power Solutions has introduced a compact, easy to operate onsite crankshaft grinding machine which is suitable for grinding and polishing of small diameters of the crankpin above 30 mm. The crankpin bearing width can be as small as 30 to 40 mm. With this latest technological advance crankshaft grinding machine, it is easy to grind the smaller diameter of the crankpin having smaller crankpin bearing width.

The crankshaft grinding machine has the main features of machining, grinding and polishing of the crankpin. The tolerances in terms of taper, ovality, and surface finish are maintained far better than the manufacturer’s recommendation.

Onsite Grinding Machine for Small Diameter

RA Power Solutions having 4 decades of experience in in situ crankshaft grinding have executed successfully repair of more than 11,000 crankshaft all over the world and are leaders in this field.
