Abstract

The invention discloses a micro structure hard alloy turning tool blade for cutting AISI201. The micro structure hard alloy turning tool blade comprises a rake face, wherein a cutting edge is arranged at the sharp corner of the rake face, one side of the cutting edge is a main cutting edge, the other side of the cutting edge is a tool mirror cutting edge, and the inner side of the cutting edge is a cutting edge near area; and a microgroove is arranged in the near area of the cutting edge, and the microgroove is of an asymmetric shoe-shaped gold ingot-shaped structure with unequal width and unequal depth on the whole. The blade has the characteristics that the near-field cutting temperature reduction effect of the cutting edge is better, the durability of the blade is higher, and the service life is longer.

Description

technical field [0001] The invention relates to an alloy turning blade, in particular to a microstructure hard alloy turning blade for cutting AISI201. Background technique [0002] Cutting is the most important product processing method in the manufacturing industry. With the continuous advancement of cutting technology, in the processing of products such as AISI201 alloy materials, the cutting precision is gradually getting higher and higher, and the quality and service life of processed products are constantly improving. There is even a phenomenon of cutting instead of grinding. In the cutting process, the cutting edge is the main part to remove material, and the working environment of the cutting edge and the rake face area near the cutting edge is the worst. The durability, but also reduce the cutting quality. [0003] The structure of the insert is directly related to the durability of the tool, the efficiency and quality of the machining, so the reasonable design of...
