jyrsintälevy

Jyrsintälevy, also known as a milling cutter or end mill, is a type of cutting tool used in milling operations. It is typically a cylindrical tool with one or more cutting edges that rotate to remove material from a workpiece. Jyrsintälevyt come in various shapes, sizes, and materials, each designed for specific machining tasks and materials.

The primary function of a jyrsintälevy is to shape and finish workpieces. This is achieved by its rotating action, where the cutting edges engage with the material and shear off small chips. Different types of jyrsintälevyt are employed for various milling processes, such as face milling, which creates flat surfaces, and contour milling, used to create complex shapes. Peripheral milling, on the other hand, uses the side cutting edges to mill away material.

Common materials used for jyrsintälevyt include high-speed steel (HSS), tungsten carbide, and ceramic. HSS is a versatile and cost-effective option, while tungsten carbide offers superior hardness and wear resistance, making it suitable for machining harder materials. Ceramic jyrsintälevyt are used for high-speed machining of difficult-to-cut materials. The design of the flutes (helical grooves on the cutting surface) also plays a crucial role in chip evacuation and the overall efficiency of the cutting process. The number of flutes can vary, with more flutes generally suited for finishing passes and fewer flutes for roughing operations.
