Template-free furnace brazing single-layer diamond abrasive particle ordered arrangement brazing method

Abstract

The invention discloses a template-free furnace brazing single-layer diamond abrasive particle ordered arrangement brazing method. The method comprises the following steps of 1, base body pretreatment work, specifically, a base body is ground to be flat and then cleaned and dried for later use; 2, brazing filler metal pre-leveling work of the base body, specifically, a layer of brazing filler metal is manually applied, and then the brazing filler metal is scraped to be flat through a scraper; 3, order abrasive particle arranging work, specifically, a certain amount of diamond abrasive particles are scattered on a screen of which the lower part is adhered with an adhesive tape, the stacked diamond particles are dispersed by using a brush, and the abrasive particles which are not adhered by the adhesive tape are blown away through compressed air; 4, sand feeding, specifically, a layer of glue with a certain thickness is applied on the base body, then the coated glue layer is covered with the adhesive tape, and the adhesive tape is removed after heating and curing; and 5, the base body is put into a vacuum annealing furnace to be brazed. According to the method, uniform and ordered arrangement of the diamond abrasive particles is achieved with the lowest cost and the most convenient test process, the abrasive particles obtained after brazing are good in equal height, the exposure height is considerable, and the holding force of the brazing filler metal to the abrasive particles is large.

Description

technical field [0001] The patent of the present invention relates to the manufacture of abrasive grains and abrasive tools, especially the design of a single-layer diamond abrasive brazing process in which the single-layer diamond abrasive grains are brazed in an orderly manner without a template. Background technique [0002] The orderly arrangement technology of diamonds is to realize the regularization and serialization of the arrangement of diamonds on the tool surface through certain means. Relevant data show that the service life of diamond tools arranged in an orderly manner is several times that of tools arranged randomly. service life and improve the quality of the machined surface. At present, the orderly arrangement methods of abrasive grains mainly include hole template method, laser rapid prototyping technology, and electrostatic arrangement method. The hole template method is to process regularly arranged holes with a diameter equal to the diameter of diamon...
