Method for manufacturing cross section of coated abrasive tool

Abstract

The invention provides a method for manufacturing a cross section of a coated abrasive tool. The method comprises the following steps of: 1) cutting the coated abrasive tool according to the size of an inner hole of a pointing machine; 2) putting the coated abrasive tool with an appropriate size into the inner hole by adhering the cross section of the coated abrasive tool to the bottom of the inner hole of the pointing machine, erecting the coated abrasive tool at the center position of the bottom of the inner hole, and pouring pointing powder into the inner hole of the pointing machine so as to fill the residual space in the inner hole; 3) performing press fitting on the coated abrasive tool and the pointing powder, and drying and curing at a high temperature; and 4) taking out the pointed and cured coated abrasive tool from the inner hole of the pointing machine, and grinding and finishing the cross section of the coated abrasive tool on a sample grinding machine. The cross section of the coated abrasive tool, manufactured by the method provided by the invention, can be directly ground and finished; the ground and finished cross section is smooth and clear and is consistent in uniformity; and key parameters, such as the primer thickness and abrasive materials, of the cross section can be quantitatively observed and researched.

Description

technical field [0001] The invention relates to a method for manufacturing a coated abrasive cross section. Background technique [0002] Coated abrasives are a type of abrasives that use adhesives to adhere abrasives to flexible substrates (cloth or paper, etc.), also known as flexible abrasives. ) and base material (cloth or paper, etc.) are composed of three parts, such as figure 1 . Commonly used coated abrasives include abrasive cloth (paper) and abrasive belts, which are widely used for grinding, polishing and polishing of non-metallic materials such as metal materials, wood, ceramics, and plastics. In the process of research, improvement and development of coated abrasives, it is necessary to observe and study the thickness of the adhesive layer and abrasives of the coated abrasives, that is, to observe the microstructure of the cross-section of the coated abrasives. However, due to the flexible characteristics of coated abrasives, it is difficult to directly obser...
