A kind of machine clip cutting knife and its processing method

Abstract

The invention discloses a machine-clamped cut-off tool and a machining method thereof. The machine-clamped cut-off tool comprises a tool body. A tool blade is connected to the head of the tool body through a fixing bolt. The back angle of the tool is 5-8 degrees. The matching surface of the tool body and the tool blade adopts multi-curved surface matching. The tool blade is straight. The external contour of the tool body is cuboid. The tool blade is provided with a cutting tool head. The cutting tool head comprises a cutting edge, a chip containing groove, a front tool surface, a main back tool surface, an auxiliary back tool surface, an edge strip, a sleeking edge and a chip curling groove. The main back tool surface is the front side surface of the tool blade. The front tool surface is the top surface and the bottom surface of the tool blade. The auxiliary back tool surface is the left-right side surface of the tool blade. The intersecting line of the front tool surface and the main back tool surface forms the cutting edge. The edge strip is arranged on the auxiliary back tool surface. The intersecting line of the front tool surface and the edge strip forms the sleeking edge. The front tool surface is provided with the chip curling groove and the chip containing groove. The chip curling groove communicates with the chip containing groove and is formed between the cutting edge and the chip containing groove. The machine-clamped cut-off tool is stable in cutting and high in production efficiency, and the stability and the durability of the tool body clamping tool blade are improved.

Description

technical field [0001] The invention belongs to the field of machine tool cutting tools, and in particular relates to a machine clip cutting tool and a processing method thereof. Background technique [0002] In the existing CNC lathe processing process, the cutting operation of the workpiece mainly depends on the machine clamp cutting tool, and the cutting of the workpiece mainly adopts the machine clamp cutting tool. Ordinary cutting knives generally use high-speed steel (W18Cr4V) and cemented carbide (YT or YG) to make integral knives or coated blade machine clamping knives. This type of cutting knife generally has problems such as large chip deformation, large cutting force, relatively concentrated cutting heat, poor tool rigidity, and difficult chip removal; and it is prone to chatter during the cutting process, and the blade often Abnormal breakage occurs, which will damage the cutter body for the machine clamping cutter, increase the manufacturing cost and affect the...
