Building on this legacy, our advanced onsite crankshaft grinding machine equipped with an electric motor system ensures precise in-situ crankshaft repair, delivering higher efficiency and significantly reduced downtime.

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 is equipped with a Variable Frequency Drive (VFD), enabling precise control of speed and accurate adjustment of RPM as per operational requirements.

ii) It delivers stable performance even at low speeds, ensuring consistent control for high-precision grinding applications.

iii) With fewer moving components, the electric motor requires minimal maintenance, resulting in improved reliability and reduced downtime.

iv) The electric motor-driven onsite crankshaft grinding machine eliminates the need for a compressor, unlike pneumatic systems, making it more efficient and convenient to operate.

This machine is ideal for onsite crankshaft grinding of shafts with diameters up to 700 mm.

The onsite crankshaft grinding machine is engineered to operate even while the vessel is in motion. This eliminates the need to halt operations for repairs, saving significant time and minimizing downtime. This capability is especially beneficial for auxiliary engine crankshaft repairs.

The machine is cost-effective and delivers excellent return on investment. It is highly recommended for shipping companies, heavy industries, and power plants operating multiple engines or repair workshops. In most cases, the investment is recovered within just 2–3 repair jobs.

We also provide comprehensive training to customers, covering both operation and maintenance of the machine. The training program equips technicians with practical, hands-on skills in crankshaft grinding and polishing, ensuring efficient and reliable performance in real-world conditions.

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 onsite crankshaft grinding machine delivers significant operational and financial advantages:

Eliminates the need for dismantling and transporting the crankshaft
Minimizes vessel downtime and prevents operational delays
Reduces repair expenses and logistics costs substantially
Enables immediate repairs during voyage, improving efficiency
Extends the service life of the crankshaft and associated machinery

With continuous advancements in onsite machining technology, the electric motor-operated crankshaft grinding machine marks a major breakthrough in precision engineering and cost-effective maintenance. It offers a dependable and efficient solution for industries focused on reducing downtime while maintaining high standards of performance and accuracy.
