This invention discloses a roughing and finishing integrated turning insert, belonging to the technical field of metal cutting tools, comprising a cutting section and sidewalls. The cutting section forms multiple cutting zones, including a sequentially connected tip area, a first cutting zone, a second cutting zone, and a third cutting zone. By dividing the cutting section into multiple cutting zones, the insert forms a spatially varying structure with progressively decreasing sharpness and structural strength. The insert exhibits a characteristic where the edge sharpness gradually decreases in the positive direction, while the edge strength and impact resistance gradually increase. This allows for a transition from high cutting force to high load-bearing capacity when different cutting zones are selected for different machining stages, enabling a single tool to cover all machining conditions from roughing to semi-finishing to finishing, fundamentally reducing tool change frequency and improving machining continuity and efficiency.

This invention relates to the field of agricultural machinery technology, specifically a soil deep tillage and straw crushing composite tillage machine. The invention features a deep tillage component and a rotary tillage component arranged side-by-side on the frame. The deep tillage component in front and the rotary tillage component behind achieve initial deep tillage, soil segmentation, and secondary crushing of the soil. The arc-shaped, convex vertical blades have their blade edge 'a' facing the direction of travel of the frame, reducing resistance during blade movement and improving the continuity and sharpness of cutting through obstacles in front. Rotary tillage blades with different radii can cut straw roots in the soil into multiple segments, resulting in a wider range of cutting and disturbance of straw roots in the soil, thus increasing the coverage radius of the rotary tillage and improving the degree of soil crushing.
