Machining Materials

• (M) - Stainless Steels (Stainless Steel - Inox)
• (P) - Steels - Alloy Steels (Steel - Alloy Steel)

Chipbreaker

• (MM) - Geometry for general machining of stainless steels. It features a relatively large rake angle (rake angle) for smoother chip flow and a reinforced cutting edge with a flat section on the edge (T-land). Suitable for medium machining on stainless steel and steel. Combines toughness (toughness) and high wear resistance (wear resistance)

Grade

• YG2025 – New CVD grade for stainless steels with high speed (M15–M35). New CVD TiCN - Al₂O₃ coating technology. Combination of new substrate and coating for excellent wear resistance and minimization of built-up edge formation. Also works excellently on steels - alloy steels (ISO P group)

Feed

• Fn = 0.08~0.25 mm/rev

Cutting Speed

• (P1-5) - Vc=120~220 m/min
• (P5-9) - Vc=120~200 m/min
• (M12-13) - Vc=170~220 m/min
• (M14) - Vc=150~200 m/min

Turning inserts from YG1, a top 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 on 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 set to achieve maximum tool performance and life.
