Rubber roller grinding wheel and manufacturing method thereof

Abstract

The invention discloses a rubber roller grinding wheel and a manufacturing method of the rubber roller grinding wheel and belongs to the technical field of solidification grinding tools. The manufacturing method of the rubber roller grinding wheel comprises the following steps that an alumina hollow ball and a low-temperature and high-strength bond are mixed in the mass proportion of (80-90):(20-10), 1-3% of dextrin powder and 4-6% of dextrin fluid are added and mixed evenly with the total weight of materials of the binary formula as the datum, materials are placed in a die in a certain specification, flattening is achieved through combing, forming is achieved through pressing of a press, and the required rubber roller grinding wheel is obtained after demolding, drying and sintering conducted in a kiln. The rubber roller grinding wheel is high in pore rate, chip removal and heat dissipation are easy, vibrating lines and scratching marks are avoided when a workpiece is ground, the workpiece machining quality can be well improved, labor efficiency is improved, and application and popularization are easy.

Description

technical field [0001] The invention relates to a rubber roller grinding wheel and a preparation method thereof, belonging to the technical field of consolidated abrasive tool manufacturing. Background technique [0002] In the manufacturing technology of bonded abrasive tools, since it is very easy to block the pores on the surface of the grinding wheel when grinding rubber roller workpieces, the silicon carbide series grinding wheels with large pores are usually used to facilitate chip removal and heat dissipation during grinding. However, pore-forming agents such as refined naphthalene and sulfur are often added in the manufacture of large-pore grinding wheels, which have the following three problems: 1. Since refined naphthalene and sulfur are volatile and produce toxic gases during drying and firing, they are harmful to environmental sanitation and human body. There are great hazards to health. 2. Due to the existence of a large number of pores, especially large pores,...

Problems solved by technology

However, pore-forming agents such as refined naphthalene and sulfur are often added in the manufacture of large-pore grinding wheels, which have the following three problems: 1. Since refined naphthalene and sulfur are volatile and produce toxic gases during drying and firing, they are harmful to environmental sanitation and human body. health hazard

2. Due to the existence of a large number of pores, especially large pores, the holding force between the bond and the abrasive is weakened, and the bond bridge is prone to breakage, thereby reducing the rotational strength of the grinding wheel and affecting the service life of the grinding wheel

3. Refined naphthalene and sulfur are relatively expensive chemical products, which increase the manufacturing cost of large-pore grinding wheels

Moreover, in terms of the use of large hole grinding wheels, there are also the following two problems: 1. The grinding wheel is prone to poor chip removal and poor heat dissipation; 2. The workpiece is prone to vibration marks and scratches during grinding traces, reducing the processing quality

If you want to get the ideal rubber roller silicon carbide macroporous grinding wheel product, you must limit the porosity in the production process to ensure that the grinding wheel has a certain hardness and sufficient strength for use, otherwise the quality and service life of the grinding wheel will be reduced
