Jyrsintälevyjä

Jyrsintälevyjä, also known as milling inserts or cutting inserts, are specialized tools used in milling operations. They are typically made of hard materials such as tungsten carbide, ceramic, or cubic boron nitride, designed to withstand high temperatures and forces generated during machining. These inserts are mounted onto a milling cutter body, which rotates and removes material from a workpiece. The replaceable nature of jyrsintälevyjä allows for quick changes to different cutting geometries or to replace worn-out edges without needing to replace the entire cutter.

The design of a jyrsintälevy is crucial for its performance and the quality of the finished surface. Different shapes, such as square, triangular, or round, are chosen based on the machining task. Edge preparation, including honing and coating, further enhances their durability, wear resistance, and ability to cut efficiently. Coatings, often made of titanium nitride (TiN) or aluminum oxide (Al2O3), reduce friction and heat, extending the life of the insert.

Jyrsintälevyjä are employed across various industries, including automotive, aerospace, and general manufacturing, for operations like face milling, shoulder milling, and slotting. Their use enables high-volume production and precise machining of complex shapes. The selection of the correct jyrsintälevy is dependent on factors such as the workpiece material, desired surface finish, cutting speed, and feed rate.
