We have recently introduced an onsite crankshaft grinding machine operated by an electric motor system.

This offers several advantages, as outlined below:

i) The electric motor provides precise speed control via a VFD (Variable Frequency Drive), allowing accurate adjustment of RPM as per the requirement.

ii) It ensures stable low-speed operation, which can be easily controlled and maintained for high-precision grinding.

iii) The electric motor requires less maintenance, as it has fewer moving parts.

iv) The electric motor-driven onsite crankshaft grinding machine completely eliminates the need for a compressor, which is required in pneumatic-driven equipment.

This machine is suitable for on-site crankshaft grinding with diameters up to 700 mm.

The onsite crankshaft grinding machine is designed in such a way that it can be operated even while the vessel is sailing. This saves considerable time, as there is no requirement to hold the vessel for repairs. This feature is of great advantage, especially in the case of repairs of the auxiliary engine crankshaft.

The cost of the machine is very low. We strongly recommend this machine for shipping companies and heavy industries operating multiple power generation units and engine repair workshops. Users typically recover their investment in an on-site crankshaft grinding machine within 2–3 jobs. We provide comprehensive training to customers on operating and maintaining the machine. During the training, we equip technicians with practical skills in crankshaft grinding and polishing.

Why Choose an Electric Motor Over a Pneumatic System?

While pneumatic systems have been widely used in the past, the electric motor-operated crankshaft grinding machine offers significant advantages:

1. Better energy efficiency and reduced operational cost
2. No dependency on external air compressors
3. Consistent performance even in remote or challenging environments
4. Improved control leading to superior surface finish and accuracy
5. Reduced noise and vibration compared to pneumatic systems

Benefits for Shipping & Heavy Industries

The adoption of an electric motor-driven on-site crankshaft grinding machine provides several operational and financial benefits:

1. Eliminates the need for dismantling and transportation
2. Reduces vessel downtime and operational delays
3. Saves significant repair and logistics costs
4. Enables immediate repair during voyage
5. Ensures a longer life of the crankshaft and machinery

With advancements in on-site machining technology, the electric motor-operated on-site crankshaft grinding machine represents a major step forward in precision engineering and cost-effective maintenance. It is a reliable and efficient solution for industries aiming to minimize downtime while maintaining high standards of performance and accuracy.

Necessity for Onsite Crankshaft Grinding and Polishing Machine

We observe that after continuous running of the engine and crankshaft, it is important to inspect the crankshaft for the following main parameters during a major engine overhaul:

1. To check the taper and ovality of the crankpin/main journal diameter.
2. To check the surface finish of the crankpin/main journal.
3. Inspection of hardness and the presence of cracks.
4. Visual inspection for radius fillet and lubricating oil hole.

If the crankpin or main journal deviates beyond the manufacturer’s limits, operators must grind and polish the crankshaft.. Hence there is a requirement of crankshaft grinding machine which is capable of maintaining the tolerances as stipulated in the manufacturer’s manual.

Change of Technology – In situ Crankshaft Grinding & Polishing Machine

In the past, operators always used bench-type crankshaft grinding machines. They installed these machines in a workshop and had to disassemble the engine, remove the crankshaft, pack it, and transport it to the designated workshop. This process is now outdated.

Technology has changed. Portable, lightweight, and easy-to-operate in situ crankshaft grinding and polishing machines have replaced heavy-duty, expensive bench-type machines. Operators no longer need to remove the crankshaft from the engine block, as they can grind and polish the crankpin or main journal onsite. They insert the machine through the inspection window.

Main Features of Revolutionary Onsite Crankshaft Grinding and Polishing Machine

1. Excellent on-site grinding equipment replaces the outdated heavy-duty bench-type crankshaft grinding machine.
2. The onsite crankshaft grinding and polishing machine is portable and operators can easily carry it onboard a vessel, to a power plant, or any installation worldwide
3. Easy to operate and easy to maintain.
4. We designed the on-site crankshaft grinding and polishing machine to maintain close tolerances in taper, ovality, surface finish, runout, and other parameters. All meet the manufacturer’s specifications.
5. Free onsite training in our workshop is provided.

Quality Aspect of In situ Crankshaft Grinding Machine

We are an ISO-certified company. We strictly follow all quality control norms during machine manufacturing.

Main body of the machine is manufactured out of titanium steel which has the inherent quality of absorbing the vibrations. This facilitates to undertake grinding and polishing of crankshaft even while sailing of the vessel. We subject every part to stringent inspection and improve metallurgical properties over time based on field trials and reports.

RA Power Solutions prices the in situ crankshaft grinding machine affordably for shipping companies, power plants, and engine repair workshops. The cost of an in situ crankshaft grinding and polishing machine is recoverable in two or three assignments. Stop paying exorbitant prices to European companies for the repair of the crankshaft and own a machine.

RA Power Solutions created the onsite crankshaft grinding and polishing machine from forty-five years of experience in this field

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