Abstract

The invention relates to a preparation method of a single-layer brazed diamond tool. The preparation method comprises the following steps of providing a steel base body of the diamond tool; providing a laser brazing system; providing diamond abrasive particles with metal coatings; providing NiCr alloy powder containing an active agent as brazing filler metal; starting a laser brazing system; turning on a power supply of an electromagnetic coil, wherein the electromagnetic coil generates an electromagnetic field and acts on the diamond abrasive particles with the metal coatings; enabling a laser head, together with a coaxial powder feeding nozzle, a paraxial feeding nozzle and the electromagnetic coil, to move along a brazing path; and after the laser head moves to the tail end of the brazing path, turning off a laser, a powder feeder, a feeder and the electromagnetic coil power supply and the argon cylinder, and completing laser brazing. The invention further provides a preparation system of the single-layer brazed diamond tool. The problems that in the process of preparing the diamond tool through laser brazing, diamond abrasive particles drift on the surface of a brazing molten pool, and consequently the diamond abrasive particles are subjected to thermal damage, shallow in embedding depth, agglomerated and the like are solved.

Description

[0001] field of invention [0002] The invention relates to the field of diamond tool processing, in particular to a method and system for preparing a single-layer brazing diamond tool. Background technique [0003] Diamond has the highest hardness, rigidity and excellent wear resistance, corrosion resistance and chemical stability, making diamond widely used in various grinding tools. The superabrasive tools currently used in production are generally made by multi-layer sintering or single-layer electroplating process. The abrasive grains are only mechanically embedded and embedded in the bonding layer, and the holding force is not large. It is easy to cause the abrasive to fall off prematurely due to insufficient holding force, resulting in waste. [0004] At present, the manufacturing process of single-layer high-temperature brazed diamond grinding wheel mainly depends on vacuum brazing, but vacuum brazing has the following limitations in practical application , Diamond a...
