Cemented carbide is a very high hardness material and is widely used in cutting tools mainly used for metal cutting. In the mechanical processing industry, the alloys or tungsten steels referred to generally refer to such cemented carbide materials. Carbide tools can be used to gain many advantages. Compared to high-speed steel tools, in most cases, machining workpieces with carbide tools not only yields better surface quality but also higher processing speeds; carbide tools can withstand higher temperatures. Cutting heat is also the main reason for achieving higher metal removal rates. When machining high-alloy steel or stainless steel, such as non-processable materials, or in high-volume production and capacity expansion, such as high-speed steel tools are prone to rapid wear, the use of carbide tools usually makes the cutting performance Better.
The origin of cemented carbide blades
The industrial application of cemented carbide tools in metal cutting began in the 1930s. Since then, cemented carbide has evolved into the most common tooling material to date. Tools of relatively small size are often made of solid carbide; non-solid carbide tools use carbide only in the cutting area. Early non-solid carbide tools often welded hard alloys to the body. By the 1940s, carbide tool manufacturers had begun to produce tools that clamped interchangeable machine-clamping blades and benefited. Compared with the earlier welding tools, this brain-opening technical innovation and the use of mechanical clamping structures make the tool strength higher; now it has been recognized as a landmark invention, not only in the tool manufacturing field. It also includes advanced and efficient processing for the entire metalworking industry.
This long-term advancement has opened up a vast space for improvement in the field of manufacturing and has immediately improved the load carrying capacity of the tool, enabling the tool to have the ability to quickly remove metal. In addition to ensuring that the blade is easier to replace and the cost is reduced due to wear failure or damage, the cutting module and the body can be separately manufactured. Blade replacement often requires consideration of its shape. There are several ways to quickly replace a failed cutting edge. In addition to indexing along the center axis of the blade, there are also cases where the front and back of the blade are reversed. The most widely recognized term for "translatable inserts" is now known as: disposable tips, replaceable blades, and replaceable inserts.
