How to Expend the Lifespan of a Grinding Wheel? Grinding Conditions and Wear Calculations

A complete guide to grinding wheel technology, Knowledge Column, Science Classroom /

The lifespan of a grinding wheel is closely related to its wear. As long as no “abnormal conditions” occur, a grinding wheel can generally be deemed usable and continue its operation.

This article introduces several key aspects of grinding wheel wear, methods for calculation, and ways to address wear issues. If you’re interested, follow along for more insights.

In grinding operations, the lifespan of the grinding wheel significantly affects both machining efficiency and quality. The usable life of a grinding wheel is influenced by multiple factors, including: Bonding strength, workpiece speed, wheel rotational speed, depth of abrasive penetration. Different grinding conditions can alter the rate of wheel wear. This explains why a grinding wheel may perform well under one set of conditions (Method A) but poorly under another (Method B). Understanding how to calculate the grinding ratio and specific wear rate can help in selecting the right grinding wheel, which is crucial for improving production efficiency and reducing costs.

The Difference Between Dry Grinding and Wet Grinding

Knowledge Column, Science Classroom /

Dry grinding and wet grinding are two common techniques in material processing. Dry grinding requires no liquids, making it suitable for rough machining with lower costs, but it generates dust. Wet grinding uses cooling liquids to reduce friction and heat, making it ideal for precision processing and enhancing product quality, albeit with higher costs. Choosing between the two depends on processing needs, material properties, and environmental considerations.
