Appropriate foaming can significantly improve the polishing process, resulting in better surface finish and shorter processing time. However, excessive foaming or a lack of foam can lead to longer processing time or poor polishing results. This article outlines the potential causes of foaming issues, explains their impacts, and provides solutions to improve processing efficiency and workpiece quality.
Grinding processing is a precision surface treatment technology, where controlling the surface roughness of the workpiece is crucial for quality. Surface roughness affects appearance and functionality, such as wear-resistance. The article discusses the definition of surface roughness, influencing factors, and improvement methods, emphasizing the importance of selecting suitable grinding wheels and controlling various parameters to enhance processing quality.
In product manufacturing, surface quality is a critical factor. Surface roughness refers to the tiny irregularities on a surface that affect functionality and durability, while smoothness describes the degree of surface flatness and light reflection. Roughness impacts gloss; the rougher the surface, the lower the gloss. To improve gloss, polishing materials are often used to remove minor irregularities, achieving a smoother surface. Understanding these concepts and effectively controlling roughness and gloss is key to ensuring high product quality, enhancing both performance and appearance.
RA (Roughness Average) and SA (Surface Area) are two measurement indicators of surface roughness. RA is the most commonly used two-dimensional roughness parameter, evaluating surface smoothness by calculating the arithmetic mean of the absolute deviations of all points on the surface profile line from the reference line over the measured length. It is typically used for roughness detection on flat surfaces. On the other hand, SA is a three-dimensional surface roughness indicator that takes into account the height variations and other features of the surface profile. It is often used for more complex surface analyses, such as high-precision manufacturing or optical surface treatments. SA provides a more comprehensive view of surface roughness, making it suitable for applications that require detailed three-dimensional data.
Surface roughness is a standard established by industrial norms, but upon closer inspection, the same Ra value can correspond to different waveforms. To improve yield, we need to explore other methods that can enhance our measurement accuracy.
