Jyrsinterät

Jyrsinterät is a Finnish term that translates to "milling cutters" in English. These are rotary cutting tools used in milling operations to remove material from a workpiece. Milling cutters come in a wide variety of shapes, sizes, and configurations, each designed for specific applications and materials.

The basic principle of a milling cutter involves a rotating tool with one or more cutting edges. As the cutter rotates, its edges engage with the workpiece, shearing off small chips of material to create a desired shape or surface finish. The geometry of the cutting edges, the rake and clearance angles, and the material of the cutter itself are all crucial factors determining its performance.

Common types of milling cutters include end mills, which can cut axially and radially, face mills, used for creating flat surfaces, and shell mills, which mount onto an arbor. Other specialized cutters exist for tasks like grooving, threading, and gear cutting. The materials used for milling cutters often include high-speed steel (HSS), carbide, or ceramics, chosen for their hardness, wear resistance, and ability to withstand the high temperatures generated during cutting. Proper selection and maintenance of milling cutters are essential for efficient and precise machining.
