Problems solved by technology

After the existing abrasive grains support the abrasive tool, during the grinding process, the existing abrasive grains have a relatively rough surface at the beginning, and the grinding effect is good, but as the grinding time prolongs, the surface roughness of the existing abrasive grains decreases, and the existing abrasive grains The surface of the abrasive grain becomes smoother and smoother, resulting in a rapid decrease in the grinding effect of the abrasive tool
The temperature of the existing abrasive grains is too high during the grinding process, which causes the surface temperature of the workpiece (metal) to be polished to be too high, and the surface of the workpiece to be polished becomes hot and red in a large area. After grinding, the polished part is easy to turn black and dark after cooling , lost the original bright color of the workpiece
The existing abrasive particles have a high temperature during the grinding process of the workpiece, and the particles are small and easy to fly, and finally adhere to the gap between the abrasive particles, causing the abrasive tool to be blocked and affecting the grinding effect
Existing grinding tools still have the problem that there is too much debris between the unit structures that cannot be discharged, and abrasive debris (such as stainless steel iron filings) is easy to adhere to the unit structure, resulting in a decrease in grinding force

Abstract

The invention discloses an anti-clogging stereoscopic structure grinding tool and a preparation method thereof, and belongs to the technical field of grinding tool manufacture. The grinding tool is characterized in that a grinding material layer is divided into a plurality of staggered hexagonal large unit structures (2) by meshed chip removal channels (3), the width (d) of each chip removal channel is 200-450 micrometers, micro-tooth units (4) are densely distributed on the large unit structures (2), and the distance (a) between every two micro-tooth units is 80-120 micrometers. The preparation method is characterized in that the large unit structures (2) are printed by the aid of flexible nets after a pretreatment glue layer and a resin coating are coated, and the micro-tooth units (4) formed on each large unit structure (2) by grinding materials are flattened in a cold-pressed manner. By the aid of the chip removal channels among the large unit structures, grinded parts cannot generate dark fringes or micro-scratches, grinding chips can be timely removed, and the micro-tooth units can be firmly adhered by the aid of the distance between every two micro-tooth units.

Description

technical field [0001] An anti-clogging three-dimensional structure abrasive tool and a preparation method thereof belong to the technical field of abrasive tool manufacturing. Background technique [0002] Conventional abrasive articles consist of many abrasive grains bonded together or coated on a backing, eg resin bonded grinding wheels, sandpaper, emery cloth. These abrasive articles have been used for more than one hundred years to grind and finish workpieces. A problem that has always troubled the abrasive industry is that the cut rate (the amount of workpiece material removed in a given time interval) is inversely proportional to the useful life of the abrasive article. Effective life, and can give a relatively fine and smooth surface finish on the workpiece being ground. [0003] The phenomenon of surface scratches and surface material shedding caused by external hard particles or micro-peaks on the hard surface during the relative motion of the friction pair’s dua...
