Recommended common grades for different processing metal materials:<\/strong><\/h5>\n

1. For machining ordinary carbon steel and alloy steel:<\/p>\n

Preferred choice: CVD-coated inserts (such as those with Al\u2082O\u2083-based coatings) typically correspond to the P-class (blue label).<\/p>\n

If the operating conditions require higher toughness (e.g., for interrupted cutting), PVD-coated inserts (such as TiAlN) may be selected.<\/p>\n

2. Processing of stainless steel and austenitic steel:<\/p>\n

Preferred choice: PVD-coated inserts, particularly those with TiAlN or AlTiN coatings. These coatings effectively inhibit built-up edge (BUE) formation and maintain a sharp cutting edge.<\/span><\/span><\/p>\n

Grade classification: M-class (yellow label).<\/p>\n

3. Machining cast iron:<\/p>\n

Preferred choice: CVD thick coatings (such as TiCN-Al\u2082O\u2083), which offer good wear resistance and compressive strength. The grade designation usually starts with K (red label).<\/p>\n

4. High-speed machining, high-hardness materials (hardened steel<\/a>):<\/p>\n

For finishing and continuous cutting: PVD coatings (such as AlTiN or TiSiN) are recommended; these coatings are thin and provide sharp cutting edges, while the surface compressive stress helps resist edge chipping.<\/p>\n

For heavy-duty roughing: CVD composite coatings (Al\u2082O\u2083 + TiCN) may be selected to leverage their heat and wear resistance.<\/p>\n
