A preparation device and method for abrasive tools with three-dimensional controllable arrangement of abrasive grains

Abstract

The invention discloses a preparation device of a grinding tool for three-dimensional controllable distribution of abrasive particles. A coating mechanism, an abrasive material containing mechanism, an abrasive material distributing mechanism and a curing mechanism are included. The coating mechanism forms resin of preset thickness in a coating manner. The abrasive material distributing mechanism adsorbs the abrasive particles and orderly distributes the abrasive particles in the resin of a coating table in a single-layer manner. The curing mechanism is used for curing the resin in which the abrasive particles are distributed. The invention further discloses a preparation method of the grinding tool for three-dimensional controllable distribution of the abrasive particles. Three-dimensional controllable distribution of the abrasive particles is achieved in a single-layer curing and layer-by-layer stacking manner. The problem that the abrasive particles deviate from positions in the curing process is effectively avoided. Accurate control over the positions of the abrasive particles can be achieved. The grinding tool machining efficiency is improved. The service life is prolonged.

Description

technical field [0001] The invention relates to the preparation technology of abrasive tools, in particular to a preparation device and method for abrasive tools with three-dimensional controllable arrangement of abrasive grains. Background technique [0002] Abrasive machining is a general term for the process of material removal using hard abrasive grains as cutting tools, and is an important form of material removal in mechanical processing. Abrasives are tools used for abrasive grain processing. Consolidated abrasive tools are made of many fine abrasive grains that are bonded into a consolidated state with a bond or binder to cut the tool. The role of the binder is to stick the abrasive grains together so that it has a certain shape and necessary strength. Commonly used binders are: ceramics, resins, rubber, metals and composite binders. The preparation process of a typical bonded abrasive tool is to mix and stir the abrasive grains and the binder, and then obtain the...

(2) For the methods obtained by Xinhan and Dr. Song Jianmin, both avoid how to avoid the change of the position of the abrasive grains due to the flow of the binder during the firing process of the abrasive tool. Therefore, although the two methods It can be called the orderly arrangement of abrasive particles, but the controllable arrangement of abrasive particles cannot be fully realized

At the same time, the current research on the three-dimensional controllable arrangement of abrasive particles is mostly focused on the preparation of electroplating, metal bond and vitrified bond abrasives, and there is no operational method for the three-dimensional controllable arrangement of resin bond abrasive particles.
