Cutting Materials

• (P) - Steels - Alloy Steels (Steel - Alloy Steel)

Chipbreaker

• (UM) - Geometry for general machining of steels. It has a relatively small rake angle (rake angle) and a reinforced cutting edge with a flat section on the edge (T-land). Suitable for medium machining and interrupted cutting. Combines high toughness (toughness) and wear resistance (wear resistance)

Grade

• YG3030 – Ideal for interrupted cutting in steel and stainless steels (P20–P35). New CVD TiCN - Al₂O₃ coating technology. Substrate specially designed for high toughness and balance of wear and coating chipping resistance

Feed

• Fn = 0.15~0.30 mm/rev

Cutting Speed

• (P1-5) - Vc=130~350 m/min
• (P5-9) - Vc=130~280 m/min
• (P10-11) - Vc=70~110 m/min

Turning inserts from YG1, a leading cutting tool manufacturer from Korea. The choice of the appropriate insert depends on the chipbreaker, that is the geometry that helps in breaking and removing the chip, as well as the grade, which describes the microstructure and coating of the insert and directly affects hardness and toughness. The cutting conditions (speed, feed, depth) must be carefully defined to achieve maximum tool performance and life.
