YBC351 The best combination of substrate with high wear resistance and coating composed of MT-Ti (CN), thick Al2O3 layer and TiN makes it suitable for finishing and semi- finishing of cast iron materials. SNMM190624-ER SNMM series inserts are widely used in aerospace, automobile industry, machinery manufacturing and metal processing and other fields.1. Blade type: SNMM (also known as SNMMxx, where xx stands for specific size and specification). 2. Uses: SNMM series inserts are suitable for CNC turning, especially for high-efficiency cutting and precise machining. 3. Material: The blade is made of tungsten carbide alloy material to ensure the wear resistance and durability of the blade. 4. Cutting function: SNMM series inserts have excellent cutting ability and can be used for rough turning, finishing turning and boring on different types of materials. 5. Insert Design: Insert shape and nose geometry are tailored to specific application needs to provide optimum cutting results and tool life. 6. Installation method: SNMM inserts are usually installed on the lathe tool holder by clamping or screw fixing to ensure the firm fixation and stability of the insert.
