Insitu Crankshaft Machining | Four Deacdes Years of Experience

In heavy machinery and marine engines, the crankshaft is a key component that converts the pistons’ linear motion into rotational force. Over time, crankshafts can experience wear, misalignment, or damage, which may reduce efficiency or even cause engine failure. Traditionally, repairing these issues required dismantling the engine and sending the crankshaft to a workshop, a process that is both time-consuming and expensive.

Understanding In Situ Crankshaft Machining

Insitu crankshaft machining uses specialized portable equipment to repair and restore crankshafts directly inside the engine. This approach avoids the need to transport large engine components and helps minimize downtime.

Key Processes in In Situ Machining

• Crankpin and Main Journal Grinding: Restores the shape, size, and surface finish of worn or damaged journals.
• Polishing: Smooths the surfaces to achieve the right finish for optimal bearing performance.
• Crack Detection and Hardness Testing: Checks the crankshaft for cracks and ensures its strength and durability after repair.

Benifits of In Situ Crankshaft Machining

• Reduced Downtime: Repairs are done onsite, so machinery can resume operation quickly.
• Cost-Effective: Avoids expenses for transporting and disassembling engines.
• High Precision and Quality: Advanced portable tools ensure repairs meet or exceed OEM standards.
• Versatile: Suitable for many types of engines in marine, power generation, and industrial sectors.
