In this case, special attention should be paid to the temperature rise of the workpiece to prevent dimensional errors, surface burns, or other thermal damage due to overheating.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color wp-elements-4cf945d05012796c794a38094d7531da\" id=\"&#x7D50;&#x8AD6;\">Conclusion<\/h2>\n\n<p class=\"has-medium-font-size\">Grinding heat is a phenomenon generated by the conversion of mechanical energy into heat energy during the grinding process, which is mainly caused by high-speed friction between the abrasive and the workpiece.<\/p>\n\n<p class=\"has-medium-font-size\">In order to effectively control the grinding heat, it is necessary to take reasonable countermeasures to reduce the generation of grinding heat, such as using slurry with good cooling effect, selecting suitable grinding wheels, reducing grinding wheel turnover speed, reducing the amount of plunge, increasing the feed and dressing the grinding wheel in time. In addition, for grinding operations with a large contact area, such as internal grinding, cooling and heat dissipation measures should be strengthened. By effectively managing the grinding heat, the surface quality and dimensional accuracy of the workpiece can be ensured, and the machining stability and service life of the grinding wheel can be improved.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading has-ast-global-color-0-color has-text-color has-link-color
