Introduction to Fluid Polishing and AFM

"Fluid Polishing and Abrasive Flow Machining (AFM) are surface treatment and precision machining techniques commonly used to improve the quality and precision of workpiece surfaces. Here is an introduction to these two processes:

 

**Fluid Polishing:**

 

1. **Function:** Fluid polishing involves applying a special liquid medium to the workpiece surface, typically containing abrasive particles or polishing materials, to enhance surface quality. This process helps to remove surface defects, improve smoothness, reduce roughness, and enhance the appearance of the workpiece.

 

2. **Working Principle:** In fluid polishing, the workpiece is typically placed together with the polishing medium in a closed container and then agitated or vibrated to make the medium flow over the workpiece surface. The abrasive particles in the polishing medium interact with the workpiece surface, gradually removing uneven surface layers.

 

3. **Applications:** Fluid polishing is commonly used for surface treatment of high-precision parts and devices, such as optical lenses, jewelry, plastic molds, medical equipment components, and more.

 

**Abrasive Flow Machining (AFM):**

 

1. **Function:** Abrasive Flow Machining is an advanced surface treatment technology designed to remove internal surface irregularities from workpieces and improve surface smoothness. It can handle complex internal channels and passages.

 

2. **Working Principle:** AFM uses a special fluid medium containing abrasive particles. This medium is pushed through the workpiece's channels and passages under pressure, while the abrasive particles flow within the medium and interact with the workpiece's inner surface, removing uneven material.

 

3. **Applications:** AFM is commonly used in aerospace, automotive manufacturing, and industrial sectors to improve the internal surface quality of components such as turbine engine parts, automotive engine components, hydraulic cylinders, and more.

 

In summary, fluid polishing and abrasive flow machining are both surface treatment methods aimed at enhancing the quality and precision of workpiece surfaces. They find widespread use in various application areas and can be chosen based on specific workpiece requirements and processing needs. These processes contribute to improving the performance and reliability of industrial products."
