Introduction<\/strong><\/p><p>Not all diamond tools are created equal. At first glance, two blades may appear identical\u2014even if they have the same diameter or belong to the same product line\u2014but their performance on the job site can be completely different.<\/p><p>The key lies in the <strong>manufacturing method<\/strong>. This determines how much the tool cuts, what materials it can work with, its service life, and its level of precision.<\/p><p>But the most important question is: <strong>Why are there different methods?<\/strong><\/p><p>The answer lies in a fundamental engineering challenge: diamond is the hardest material in the world, but the metal that holds it in place must wear down in a controlled manner to expose new, sharp diamonds.<\/p><p>Since every material\u2014whether concrete, asphalt, steel, ceramic, or glass\u2014generates different levels of heat, friction, and wear, <strong>no single method can cover all applications<\/strong>.<\/p><p>At <strong>Marathon Diamond<\/strong>, we work with all methods because we understand something essential: choosing the wrong manufacturing system is the quickest way to lose performance, time, and money.<\/p><p><strong>2. The Four Main Manufacturing Methods<\/strong><\/p><p><strong>Sintering (powder metallurgy)<\/strong><\/p><p>In this process, diamond powder and metal powder are pressed together and heated until they fuse without damaging the diamond.<\/p><p>It\u2019s like compressing dough until it becomes a solid block.<\/p><p><strong>Common uses:<\/strong><\/p><ul class=\"wp-block-list\"><li>General-purpose discs<\/li>\n\n<li>Wet cutting<\/li>\n\n<li>Economical applications<\/li><\/ul><p><strong>Electroplating (galvanic bonding)<\/strong><\/p><p>The diamonds are bonded using a layer of nickel deposited electrochemically onto a steel substrate.<\/p><p>It\u2019s like \u201cgluing\u201d a single layer of diamonds onto the surface.<\/p><p><strong>Common uses:<\/strong><\/p><ul class=\"wp-block-list\"><li>Ceramics and porcelain<\/li>\n\n<li>Glass<\/li>\n\n<li>Small, precise perforations<\/li><\/ul><p><strong>Vacuum brazing<\/strong><\/p><p>A single layer of diamonds is chemically bonded to the metal base using a special alloy in a vacuum furnace.<\/p><p>The bond is not just mechanical\u2014it is chemical.<\/p><p><strong>Common uses:<\/strong><\/p><ul class=\"wp-block-list\"><li>Cutting steel and metals<\/li>\n\n<li>Fiberglass<\/li>\n\n<li>Hard stone and highly abrasive materials<\/li><\/ul><p><strong>Laser Welding<\/strong><\/p><p>A high-energy laser fuses the diamond segments to the steel body, creating an extremely strong metallurgical bond.<\/p><p>It is the strongest bond on the market.<\/p><p><strong>Common uses:<\/strong><\/p><ul class=\"wp-block-list\"><li>Reinforced concrete<\/li>\n\n<li>Granite<\/li>\n\n<li>High-performance dry or wet cutting<\/li><\/ul><p><strong>3. Why These Differences Exist<\/strong><\/p><p>Each method addresses a different physical challenge associated with diamond cutting.<\/p><p><strong>A. Controlled wear (sintered)<\/strong><\/p><p>The problem is simple: the diamond wears down and stops cutting. If the metal is too hard, it traps the diamond, and the tool stops working.<\/p><p>Sintering solves this by creating a metal that wears down gradually, exposing new diamonds.<\/p><p><strong>Limitation:<\/strong> It does not withstand extreme heat or contact with steel well.<\/p><p><strong>B. Fine cutting (electroplating)<\/strong><\/p><p>For delicate materials such as ceramics or glass, an extremely fine cut is required.<\/p><p>Electroplating allows for a single layer of diamond, like a very sharp blade.<\/p><p><strong>Limitation:<\/strong> The diamonds wear down quickly, and there is no reserve.<\/p><p><strong>C. Chemical bonding (vacuum brazing)<\/strong><\/p><p>With electroplating, the diamonds can come loose.<\/p><p>Vacuum brazing creates a true chemical bond between the diamond and the metal, preventing this problem.<\/p><p><strong>Key advantage:<\/strong> The diamonds break, they do not come loose.<\/p><p><strong>D. The heat problem (laser welding)<\/strong><\/p><p>Extreme heat can destroy traditional bonds.<\/p><p>Laser welding withstands much higher temperatures and prevents the loss of segments.<\/p><p><strong>Result:<\/strong> maximum safety and durability in demanding applications.<\/p><p><strong>4.
