Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.

[0028] Unless otherwise defined, all technical and scientific terms used here...

Abstract

The invention discloses a laser processing method of a tool. The laser processing method of the tool comprises the following steps of fixing a tool holder of the tool on a processing platform of laserprocessing equipment; enabling the laser processing equipment to cut a cutting edge of a blade of the tool to form a negative chamfering surface; and enabling the laser processing equipment to cut the blade, on which the negative chamfering surface is formed, to form a relief angle connected with the negative chamfering surface. The laser processing method of the tool has the advantage of high processing efficiency.

Description

technical field [0001] The invention relates to a laser processing method of a cutting tool, in particular to a laser processing method of a PCNB cutting tool. Background technique [0002] Polycrystalline cubic boron nitride (PCNB, Polycrystalline Cubic Boron Nitride) tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, making PCNB tools widely used in the field of processing various non-ferrous metals and non-metallic materials. widely used. At present, the preparation and processing methods for PCNB cutting tools mainly include grinding processing, spark erosion processing, and chemical processing. However, the above-mentioned processing method takes a long time to process, and the blade surface of the processed tool has high roughness, which reduces the yield rate and service life of the tool. At the same time, it is difficult for the above-mentioned processing means to perform chamfering treatment o...
