R A Power Solutions extends onsite crankshaft grinding services for reciprocating equipment such as diesel engines, compressors, pumps, forging hammers, etc. We introduced an onsite crankshaft grinding machine operated by a pneumatic turbine motor about 20 years ago, and this machine is now used worldwide by leading crankshaft repair companies, large industrial groups, and shipping companies. The on-site crankshaft grinding machine with an electric motor system delivers precise in-situ crankshaft repair with reduced downtime and high efficiency.
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:
- Better energy efficiency and reduced operational cost
- No dependency on external air compressors
- Consistent performance even in remote or challenging environments
- Improved control leading to superior surface finish and accuracy
- 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:
- Eliminates the need for dismantling and transportation
- Reduces vessel downtime and operational delays
- Saves significant repair and logistics costs
- Enables immediate repair during voyage
- 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.
