M-350 Crankshaft polishing machine

Modern crankshaft manufacturing requires more than dimensional accuracy. Surface texture and microgeometry directly influence lubrication behavior, seal performance and engine durability.

Grinding Chatter Marks Increase Noise and Wear

Microscopic chatter marks remaining after grinding may affect lubrication behavior and contribute to increased wear.

Solution

The superfinishing process helps remove grinding marks and improve journal surface consistency.

Poor Oil Film Retention Causes Higher Friction

Inadequate surface texture may reduce lubrication efficiency and affect bearing life.

Solution

Optimized superfinishing helps improve lubricant retention characteristics and supports hydrodynamic lubrication.

Difficulty Controlling Functional Roughness Parameters

Traditional polishing methods often struggle to maintain stable functional roughness characteristics.

Solution

The machine supports process optimization for target surface requirements including Rz and Rpk related characteristics.

Oil Seal Wear and Leakage

Excessive surface peaks may accelerate seal wear during long-term operation.

Solution

Optimized journal surfaces contribute to improved sealing performance and reduced wear risk.
