Onsite Portable Crankshaft Grinding Machine for Marine & Industrial Engines


The Crankshaft Grinding Machine is cutting-edge equipment developed to repair crankpins and main journals on-site, avoiding the need for engine disassembly or crankshaft removal. Its precision, mobility, and innovative engineering, which reduces downtime, make it indispensable in the marine, industrial, and power-generation industries.

Key Features of the Crankshaft Grinding Machine

1. Portable & Modular Engineering

The machine’s lightweight and modular construction enables quick transportation, assembly, and operation directly at site locations—including confined engine rooms, vessels, offshore platforms, and remote industrial facilities.

2. Wide Grinding Range

With the capability to machine crankshafts from 35 mm to 700+ mm, it supports a broad spectrum of engines used in marine propulsion, diesel power plants, industrial equipment, and heavy machinery.

3. Advanced Vibration-Control Technology

Manufactured using specially developed vibration-dampening alloys, the machine ensures exceptional stability during operation. This directly contributes to a superior surface finish and precision, even in the most demanding environments.

4. Micron-Level Accuracy

The machine restores crankpins and main journals to original OEM tolerances. Ovality, taper, and size corrections are executed with high precision, ensuring long-term reliability and smooth engine functioning.

5. Combined Grinding & Polishing System

Grinding and polishing are performed in the same setup without disturbing the alignment. This integrated design saves significant time while delivering consistent journal geometry.

6. Rapid Setup & Alignment

Special fixtures and alignment tools allow the machine to be mounted quickly with perfect axial positioning. This is particularly critical in constrained spaces, as it reduces the overall repair duration.

7. Exceptional Surface Finish

The machine delivers a mirror-like surface suitable for high-speed and high-load-bearing applications, improving lubrication and extending crankshaft life.

How the Machine Operates

(i) Mounting & Fixture Alignment

Custom brackets are used for precise mounting on the crankshaft.

(ii) Measurement & Diagnosis

Dial gauges and micrometers record journal wear, taper, and ovality.

(iii) High-Precision Grinding

Controlled grinding restores the exact journal size and geometry.

(iv) Polishing

The same machine produces a smooth, bearing-ready finish.

(v) Final Inspection

Journal dimensions are rechecked to confirm OEM tolerance compliance.

Operational Advantages
Minimal Downtime

Repairs are completed onsite, significantly reducing engine outage time.

Major Cost Savings

Eliminates logistics, crane usage, transportation, and external workshop costs.
Extends Engine Life

Accurate restoration ensures long-term durability and prevents premature engine failure.

Ideal for Any Environment

Marine vessels, offshore rigs, industrial plants, and remote installations benefit from its portability and precision.
