Abstract

The invention discloses a single-layer diamond abrasive brazing method for brazing in a furnace without a template, which includes the following steps: 1. Pretreatment of the substrate, firstly grinding the substrate, then cleaning the substrate, and drying Standby; 2 Pre-level the brazing material on the substrate, first apply a layer of brazing material by hand, and then scrape the brazing material with a scraper; 3 Arrange the abrasive grains in an orderly manner, take a certain amount of diamond abrasive grains and sprinkle them on the lower part On the screen of the tape, use a brush to disperse the stacked diamond particles, and use compressed air to blow off the abrasive particles that are not stuck by the tape; On the coated glue layer, remove the tape after heating and curing; 5 put the substrate into a vacuum annealing furnace for brazing. The invention realizes the uniform and orderly arrangement of the diamond abrasive grains with the lowest cost and the most convenient test process, and the abrasive grains after brazing have good contour, considerable blade height and strong holding force of the brazing material on the abrasive grains.

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...
