kovametallityökaluilla

Kovametallityökalut, commonly known as carbide tools, are cutting tools made from cemented carbide, a composite material composed of a hard carbide powder and a binder metal. Tungsten carbide is the most common carbide powder used, while cobalt is the most frequent binder metal. This composition gives the tools exceptional hardness, wear resistance, and strength, making them suitable for machining a wide range of materials.

The manufacturing process involves mixing the carbide powders and binder metal, pressing them into desired shapes, and then sintering the compact at high temperatures. This process fuses the particles together, creating a very dense and hard material. Kovametallityökaluilla are used in various applications, including drilling, milling, turning, and stamping. They are particularly effective for machining hard metals, ceramics, and composites that would rapidly wear out conventional steel tools.

The advantages of using kovametallityökaluilla include longer tool life, higher cutting speeds, improved surface finish of the workpiece, and the ability to machine difficult-to-cut materials. However, they are also more brittle than high-speed steel tools, meaning they are more susceptible to chipping or breaking under impact or excessive vibration. Proper tool holding and machining parameters are crucial to maximize their performance and lifespan. Their widespread use across industries like automotive, aerospace, and manufacturing underscores their importance in modern machining processes.
