INSERT , Iran

A turning insert is a replaceable cutting component mounted on machining tools such as boring bars or turning holders. Inserts are typically made from tungsten carbide, ceramics, or CBN and have a high hardness rating up to 92 HRA. Their rake angle ranges from 5 to 25 degrees, depending on the operation type and workpiece material. Standard insert dimensions follow ANSI or ISO codes, such as a diameter of 12.7 mm and a thickness of 4.76 mm. The contact surface is often coated with materials like TiN or Al₂O₃, enhancing wear resistance by up to three times. The insert geometry includes rounded or angled corners with a nose radius between 0.2 and 1.2 mm, directly affecting the surface finish quality.

Turning inserts can operate at cutting speeds up to 400 meters per minute and are suitable for precision machining with feed rates between 0.05 and 0.5 mm. In industrial applications, they withstand temperatures up to 800°C without performance degradation. A clearance angle of 5 to 7 degrees reduces friction and extends tool life. Insert coding includes detailed specifications such as shape, angle, thickness, and dimensional tolerance according to ISO 1832 standards. Inserts are compatible with various holders like CNMG or TNMG, used for roughing or finishing operations. With proper lubrication and optimized cutting parameters, an insert can maintain continuous machining performance for up to 90 minutes.
