[0002] Usually, during turning operations, especially when machining sticky and plastic materials such as stainless steel and mild steel, soft and thin chips are often difficult to break. At the same time, the chips need to be separated and removed from the rotating workpiece in a timely manner. If the chips rotate and curl randomly and cannot be broken and discharged in a timely manner, chips will remain between the turning blade and the workpiece. As the cutting process continues, the chips will accumulate more and more. In this way, the chips are very likely to wind around the workpiece, tool or fixture, causing scratches on the machined surface of the workpiece and affecting the surface quality of the machined workpiece; impacting the cutting blade, causing damage and chipping of the blade, and reducing the blade life. In order to increase the overall service life of the blade, we redesigned an indexable turning blade. Content of the Utility Model
