Piston Rod Polishing

Rod seals in hydraulic cylinders must contain high-pressure fluid, enable smooth rod movement, minimize friction, and resist wear under extreme conditions. Polishing before and after corrosion treatment is key to optimal performance, and we can help you achieve that!

MP3000 Superfinishing - Piston rods

The SMP3000 Superfinishing - Piston rods machines are designed for large diameter parts. Available with various heads for superfinishing and polishing.

Polishing or finishing before applying corrosion prevention treatment serves an important purpose.

Before undergoing hard chrome plating, it is crucial to flatten the surface tops to prevent the formation of an unstable chrome layer and sharp tips. This not only ensures a more stable plating process but also reduces the need for excessive stock removal after plating, resulting in cost savings. When it comes to nitriding, minimizing stock removal after the process is essential due to the limited diffused layer. Therefore, it is recommended to perform polishing or finishing before plating or nitriding to achieve optimal results.
