Improved cutter and improvement method thereof

Abstract

The invention relates to the technical field of cutters, in particular to an improved cutter and an improvement method thereof. According to the technical scheme, the cutter comprises a cutter handle, first cutting edges and second cutting edges, the second cutting edges are arranged at one end of the cutter handle, the first cutting edges are arranged on the cutter handle on one side of the second cutting edges, phi 25 and phi 22 of the first cutting edges are respectively 10-degree spiral grooves, phi 10.1 of the second cutting edges is a straight groove, the number of the first cutting edges and the number of the second cutting edges are respectively six, and the number of the first cutting edges and the number of the second cutting edges are respectively six. The coatings on the first cutting edge and the second cutting edge are made of HA-DLC. The blade core of the second blade with the straight groove cannot cause vibration, the aperture obtained in the using process of the first blade with the 10-degree spiral groove is consistent with the standard aperture, the finish degree is required to be within Ra1.3, the finish degree can still be kept within the qualified range until the aperture is small, the service life ranges from 50,000 to 50,000 3, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to an improved cutting tool and an improving method thereof. Background technique [0002] A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. The vast majority of knives are for machine use, but some are also for hand use. Since the knives used in mechanical manufacturing are basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool. Knives for cutting wood are called woodworking knives. There is also a special category of cutting tools for geological exploration, well drilling, and mine drilling, called mine cutting tools. [0003] Tools can be divided into five categories according to the surface of the workpiece: tools for processing various external surfaces include turning tools, planers, milling cutters, external surface broaches and files, etc.; hole processing tools inclu...

AI Technical Summary

Problems solved by technology

[0004] The tools used for machining the shaft hole on the side seat of the motor are all straight grooved blades. The normal life of the straight grooved blades is between 20,000 and 40,000. The smoothness requirement is within Ra1.6. The straight grooved blades are mainly due to The poor finish is replaced, and the replaced tool with poor finish is basically caused by sticking aluminum after the outer diameter is worn, and the service life of the straight flute tool is generally relatively low
