Integral multi-edge contour knife processing method

Abstract

An integral multi-edge contour knife processing method comprises the following steps: a knife handle blank is grinded into a benchmark knife handle with the preset precision in a basic shaft system; aPCD knife head blank and the benchmark knife handle are clamped in a centering and aligning manner, and then vacuum welding is performed; and the PCD knife head blank is grinded to reach the preset precision with the benchmark knife handle as a benchmark; and a plurality of cutting edges distributed in a ring-shaped manner and a plurality of chip removing grooves positioned among the cutting edges are formed one by one through laser cutting at the end, far away from the benchmark knife handle, of the PCD knife head blank, and then an integral multi-edge contour knife is obtained, wherein theedge width of each cutting edge is 0.04-0.2 millimeters, the edge surface roughness Ra of each cutting edge is 0.1-0.4 micrometers, and the depth of each chip removing groove is 0.1-0.2 millimeters. The integral multi-edge contour knife obtained through the integral multi-edge contour knife processing method provided by the invention has an integrated multi-edge structure, thereby facilitating theimprovement of the processing efficiency and the prolonging of the service life, and guaranteeing the ideal processing quality; the economic benefit is great, thereby facilitating the promotion and the application; and the integral multi-edge contour knife processing method is especially suitable for glass or ceramic processing.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, and specifically relates to a processing method for an integral multi-edged contour cutter. Background technique [0002] Diamond has been used as a superhard tool material in cutting for hundreds of years, but natural diamond is scarce and expensive, and it is difficult to meet the needs of a large number of applications. Polycrystalline diamond (Polycrystalline diamond) is a kind of artificial diamond, which is used to replace natural diamond (single crystal). fields. [0003] The traditional polycrystalline diamond tool is made by welding the tip of the polycrystalline diamond composite sheet to the carbide blade or the base of the tool holder. In the application of multi-blade cutting tools, multiple polycrystalline diamond composite blade tips need to be welded separately. Due to the limited layout space, it is easy to cause insufficient welding strength and precision, which affects ...

AI Technical Summary

Problems solved by technology

In the application of multi-edge cutting tools, multiple polycrystalline diamond composite blade tips need to be welded separately. Due to the limited layout space, it is easy to cause insufficient welding strength and precision, which affects cutting quality and service life.

At the same time, the welded structure requires a specific operating space, and it is difficult to achieve an ideal layout in the application requirements of rapidly increasing number of blades, and cannot adapt to the development trend of high-precision and long-life cutting tools
