Manufacturing method of cutting piece

Abstract

The invention discloses a manufacturing method of a cutting piece, and belongs to the field of abrasive grinding tools. The manufacturing method comprises the following steps that 1, metal wires are woven into a metal net; 2, the metal net is cut into an annular shape; 3, phenolic resin is coated near inner holes of the annular metal net, and the coating thickness is ensured to meet the requirements; 4, the metal net is placed into electroplating equipment for electroplating diamond; and 5, white corundum, anhydrous gypsum, the phenolic resin, asphalt and an additive are crushed and sieved, and then mixed and stirred evenly to form an abrasive mixture. The manufacturing method of the cutting piece has the characteristics that the thinner cutting piece can be manufactured, and the manufactured cutting piece is long in service life and can be used for cutting hard objects.

Description

technical field [0001] The invention belongs to the field of abrasive abrasive tools, and particularly relates to a thin-film grinding wheel cutting piece for cutting metal or non-metal. Background technique [0002] In the process of industrial production and equipment maintenance, it is often necessary to cut the profiles used to meet the requirements of use. In small batch production, a grinding wheel cutting machine is often used for cutting. The principle is that the grinding wheel cutting machine drives the thin grinding wheel to rotate at a high speed. The grinding wheel rubs against the object to be cut, so that the object to be cut is decomposed, so as to complete the cutting task; most of the existing grinding wheel cutting discs are made of hard abrasives, which are bonded and pressed into thin slices with adhesives, so the production process is simple and the cost is low. However, since the hardness of the abrasive used is much higher than the hardness of the adh...

[0002] In the process of industrial production and equipment maintenance, it is often necessary to cut the used profiles to meet the requirements of use. In small batch production, grinding wheel cutting machines are often used for cutting. The principle is that the grinding wheel cutting machine drives the sheet grinding wheel to rotate at high speed. The grinding wheel rubs against the object to be cut, so that the object to be cut is decomposed, so as to complete the cutting task; most of the existing grinding wheel cutting discs are made of hard abrasives, which are bonded and pressed into thin circular slices with adhesives, so the production process is simple and the cost is low. Low; however, because the hardness of the abrasive used is much higher than that of the adhesive, the consumption of the cutting disc is mainly due to the friction between the cutting disc and the object to be cut, and the abrasive particles are separated from the adhesive, so the service life is short. At the same time, it cannot meet the cutting of hard objects to be cut
