Why is cutting coolant sprayed during metallographic cutting?

In the process of metallographic cutting of metals, spraying circulating and flowing cutting coolant onto the cutting surface is crucial. The cutting coolant can provide a cooling effect.
During cutting, high-speed friction between the grinding wheel and the metal workpiece generates a large amount of heat. If not cooled in time, the temperature of the cutting surface will rise sharply, leading to changes in the metal structure and affecting the accuracy of the metallographic analysis results.
The coolant can lubricate the cutting area, reduce the friction between the grinding wheel and the workpiece, and lower the cutting resistance, making the cutting process smoother. It can not only extend the service life of the grinding wheel but also improve cutting efficiency. In addition, the circulating coolant can timely wash away the debris generated by cutting, preventing debris from accumulating on the cutting surface, thereby obtaining a high-quality cutting surface while avoiding surface damage layers caused by insufficient cooling, which in turn improves the efficiency of subsequent grinding and polishing.

Kunshan Fuze Testing Equipment Co., Ltd.'s metallographic abrasive wheel cutting machine is equipped with an efficient cooling system to ensure excellent cooling effects during the cutting process.
