Features of the Crankshaft Grinding Machine

1. Portable Design:

• Crankshaft grinding machine specifically developed for onsite crank pin grinding and polishing in confined spaces.
• Eliminates the need to remove the crankshaft from the entablature, minimizing downtime.
• Lightweight and Ergonomic:
• We continuously optimize component weight to ensure easy handling and global transportation.
• Designed for operator comfort and convenience during repair operations.

2. High-Quality Construction:

• We build the main body with high-grade titanium alloy for unmatched strength and vibration control.

3. Precision and Performance:

• Capable of maintaining close tolerances of 0.02 mm.
• The crankshaft grinding machine is used even while the vessel is sailing, ensuring uninterrupted operations.

4. Single-Setting Operation:

• Both crankpin and main journal grinding and polishing can be performed in one setup.
• Eliminates the need for multiple adjustments during operation.

5. Versatile Functionality:

• Suitable for honing and polishing when damage is minor, without reducing the crankshaft diameter.
• Effectively removes surface line marks, pitting, and rust to improve surface finish.

6. Complete Supply Package:

• Delivered with all necessary consumables, sufficient to grind or polish one complete crankshaft.

7. Training and Support:

• A senior technician is deputed to the client’s site for comprehensive training.
• Training covers equipment operation, handling, and maintenance.

The Crankshaft Grinding Machine isn’t just portable—it’s precise.

We’re talking accuracy within 10 microns (that’s micrometer-level precision), with surface finishing that complies with international quality standards. It’s lightweight, simple to carry, and super user-friendly.

Technicians don’t need to be hardcore specialists. With a quick 1-week training (yes, literally just a week), they’re able to grind and polish crankshafts like pros.
