This not only results in poor grinding performance but also damages the grinding wheel, leading to unnecessary losses.<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>Diamond&#8217;s Low Heat Resistance<\/strong>: When grinding temperatures reach&gt; 600\u00b0C, diamond can dissolve in certain elements (like rare earth elements, La, Ce) or form carbides with some elements (like refractory transition elements, Ti, Zr), accelerating wheel wear. Therefore, diamond wheels are not suitable for high-temperature processing.<\/li>\n<\/ol>\n\n<p class=\"has-medium-font-size\">Thus, when high-speed grinding (which increases temperature) or the processing of iron elements is required, CBN wheels are the better choice.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"&#x53EF;&#x52A0;&#x5DE5;&#x5C0D;&#x8C61;&#xFF1A;\" style=\"font-size:25px\"><strong>Materials Suitable for Grinding:<\/strong><\/h3>\n\n<p class=\"has-medium-font-size\"><strong>Diamond Grinding Wheels<\/strong>: Suitable for grinding or cutting materials like tungsten carbide, carbonized iron (steel), glass, quartz, stone, shells, ceramics, refractory materials, semiconductors, graphite, tiles, asphalt, concrete, asbestos, plastics, etc.<\/p>\n\n<p class=\"has-medium-font-size\"><strong>CBN (Cubic Boron Nitride) Grinding Wheels<\/strong>: Suitable for grinding tools such as tool steel, high-speed steel, mold steel, bearing steel, stainless steel, heat-resistant steel, titanium alloys, cast iron, and steel materials hardened to over&gt; HRC45 after heat treatment.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"&#x7E3D;&#x7D50;&#xFF1A;\" style=\"font-size:25px\"><strong>Summary<\/strong><\/h3>\n\n<p class=\"has-ast-global-color-0-color has-text-color has-link-color has-medium-font-size\">As technology advances, the demands for processing and precision are increasing, making the selection of the most suitable solution more important than ever.

Diamond wheels should not be used on iron-containing workpieces, as they can catalyze the transformation of diamond into graphite, affecting performance and wearing down the wheel. When grinding temperatures exceed 600\u00b0C, diamonds are prone to melting or forming carbides, making them unsuitable for high-temperature processing. In contrast, CBN wheels are suitable for high-speed and iron-containing material processing, such as tool steel and mold steel, showcasing their unique advantages.
