How to Improve Surface Finish in Turning with the Right Cutting Inserts

Cutting insert materials are an important component of the machining process. Choosing the right cutting parameters for each material is essential in order to achieve the desired results. Different materials require different cutting parameters to achieve the best result. Here are the recommended cutting parameters for different cutting insert materials.

Carbide inserts have high hardness and are used for a variety of machining operations. It is recommended to use a low cutting speed (around 200-500 m/min) and relatively high feed rate (0.1-1.0 mm/rev). For cutting depth, it is recommended to use a maximum depth of 0.3-0.5 mm per pass. For sharpening, use a slow speed (around 800-1000 m/min) and feed rate of 0.1-0.2 mm/rev.

Cermet inserts are made of a combination of metal and ceramic material and are used for high-speed machining operations. It is recommended to use a high cutting speed (around 1000-2000 m/min) and relatively low feed rate (0.1-0.3 mm/rev). For cutting depth, it is recommended to use a maximum depth of 0.3-0.5 mm per pass. For sharpening, use a slow speed (around 800-1000 m/min) and feed rate of 0.1-0.2 mm/rev.

Ceramic inserts are made of a combination of metal APKT Insert and ceramic material and are used for high-speed machining operations. It is recommended to use a high cutting speed (around 1000-2000 m/min) and relatively low feed rate (0.1-0.3 mm/rev). For cutting depth, it is recommended to use a maximum depth of 0.3-0.5 mm per pass. For sharpening, use a slow speed (around 800-1000 m/min) and feed rate of 0.1-0.2 mm/rev.

PCD (polycrystalline diamond) inserts are made of diamond particles and are used for high-speed machining operations. It is recommended to use a high cutting speed (around 1000-3000 m/min) and relatively low feed rate (0.1-0.3 mm/rev). For cutting depth, it is recommended to use a maximum depth of 0.3-0.5 mm per pass. For sharpening, use a low speed (around 400-600 m/min) and feed rate of 0.1-0.2 mm/rev.

By selecting the right cutting parameters for each SNMG Insert material, you can achieve the desired results and ensure the optimal performance of your machining operations. It is important to keep in mind that these recommendations may vary depending on the type of material being used, the machine tool, and the cutting conditions.
