jyrsintälevyt

Jyrsintälevyt, also known as milling inserts or cutting inserts, are small, replaceable cutting tools used in milling operations. They are typically made of hard materials such as tungsten carbide, ceramics, or cubic boron nitride (CBN). These inserts are designed with specific geometries and cutting edges to efficiently remove material from a workpiece. They are held in place by an insert holder or milling cutter body, allowing for quick and easy replacement when worn.

The use of jyrsintälevyt offers several advantages in machining. Their replaceable nature means that only the worn insert needs to be changed, rather than the entire cutting tool, which reduces costs and downtime. The high hardness and wear resistance of the insert materials allow for faster cutting speeds and deeper depths of cut, leading to increased productivity and improved surface finish on the workpiece. Different types of jyrsintälevyt are available for various materials and machining applications, including roughing, finishing, and high-speed milling.

The design of a jyrsintälevy includes features like the shape of the insert (e.g., square, triangular, round), the number of cutting edges, and the type of coating applied to the surface. Coatings such as titanium nitride (TiN) or titanium carbonitride (TiCN) further enhance wear resistance and reduce friction. The selection of the appropriate jyrsintälevy depends on factors such as the workpiece material, the desired machining operation, and the cutting parameters.
