Information on Crankshaft Grinding Machine and Process | RA Power Solutions

Every crankshaft requires grinding and polishing. We are giving below a few reasons for the requirement of crankshaft grinding and polishing:

1. Although manufacturers make crankshafts from forged steel, continuous running causes the crankpin and main journal to develop taper and ovality beyond the engine manufacturer’s limits. To remove excessive taper and ovality, we grind the crankshaft. If the ovality is minor, we polish the crankpin and main journal instead.
2. Bearing line marks, pitting, and rough surface is observed. The reason can be poor quality of lubricating oil used, non-replacement of lubricating oil filters on time, poor quality of bearings, etc. The crankshaft polishing is recommended in case the bearing line marks and pitting are observed.
3. Seizure of bearing on crankpin or main journal of the crankshaft is common. In some cases, bearing material embeds on the crankpin and main journal. We recommend grinding and polishing the crankshaft to remove the material. This process also controls taper, ovality, surface finish, and other parameters according to the engine manufacturer’s specifications.

Applications of the Crankshaft Grinding Machine

To address these crankshaft defects, we need a crankshaft grinder machine to grind and polish the crankpin and main journal. In the past, before today’s advanced technology, owners had no option but to disassemble the crankshaft, pack it, and send it to a designated workshop for repairs. In the case of large crankshafts, say 5 meters in length and above, even as of data, several countries don’t have facilities for bench-type crankshaft machining, as it needs heavy investment, highly skilled manpower.

RA Power Solutions has developed a portable, light-weight, easy-to-operate In Situ Crankshaft Grinding Machine having the following features:-

Introduction of a state-of-the-art Crankshaft Grinding Machine:

1. The onsite crankshaft grinding machine introduced by RA Power Solutions is a real-term technological innovation. It has an outdated, heavy-duty, bench-type crankshaft machining. Several manufacturers of crankshaft grinding machines in Italy, Germany, and other countries have closed down their crankshaft machining manufacturing facilities.
2. The machine’s mainframe is manufactured out of titanium alloy, which has the inbuilt property of absorbing vibrations. This is of great benefit as the grinding and polishing of crankpin machining and the main journal of the crankshaft is possible even while sailing the vessel.
3. The machine’s compact and lightweight design allows us to transport it to any site in the world by air as accompanied baggage. We kept the total weight to a minimum, making it easy to handle and reducing transportation costs.
4. The machine is designed and capable of achieving closed tolerances strictly as per the manufacturer’s recommendation. It can execute grinding and polishing of crankshafts of all engine manufacturers and can meet their stipulated parameters in terms of taper, ovality, surface finish, parallelism, etc.
5. The machine is operated either by a pneumatic turbine or an electric motor, depending on the customer’s choice.
6. Presently, the machine is available in the range from 35 mm to 700 mm.
7. Training and maintenance is an important part of our company sales policy. We extend training on dummy crankshafts in our workshop or even at the client’s premises.
8. The cost of equipment is of great importance in this time of recession, shipping and industries, in general, are going through.
9. The cost of the machine is negligible in comparison to the heavy-duty bench-type stationary crankshaft machining.
10. We have sold more than 70 machines worldwide. We also trained technicians to operate and maintain them.

Crankshaft Grinding Machine Exporter

Companies now prefer a portable crankshaft grinding machine that they can take to the site for repairs. Removing the crankshaft from the main equipment, packing it, and sending it to a workshop is neither practical nor financially feasible. This process is especially difficult for heavy-capacity engines installed on vessels or in diesel power plants.

The portable crankshaft grinding machine, which we can take to the site, has become a blessing for vessel owners and heavy engineering companies. Many of them lack crankshaft grinding and polishing services in their country. Previously, they had to send the crankshaft to another country or replace it with a new one at a high cost.

RA Power Solutions Pvt. Ltd. manufactures portable, lightweight, and easy-to-operate crankshaft grinding machines up to 700 mm. The onsite crankshaft grinding machine costs far less than conventional bench-type crankshaft machining available in the market.

Crankshaft Grinding Process

The machine is very handy and can be easily operated for the crankshaft grinding process.
We recommend the crankshaft grinding machine for onsite crankshaft reconditioning and polishing without removing it from the block. It can grind and polish any cylindrical shaft up to 700 mm in diameter, regardless of bearing length, which can reach 600 mm or more.

We are executing crankshaft grinding repair services in Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates, Vietnam, UK, USA and other countries.
