Diamond grinding wheel applied to grinding of inner wall of cast pipe

Abstract

The invention belongs to the technical field of superhard abrasive tools, and particularly discloses a diamond grinding wheel applied to grinding of the inner wall of a cast pipe. A diamond is brazed on the wheel face of a grinding wheel base body to serve as the grinding face, the exposure is high, chip removal is easy, and the grinding efficiency is high. Compared with a resin grinding wheel in the prior art, the comprehensive grinding efficiency can be improved by 20% or above, dust and peculiar smell are basically not volatilized in the grinding process, and the working environment is greatly improved. The wheel face of the grinding wheel base body is of a designed novel structure, the grinding wheel base body is matched with the movement working condition of inner wall grinding equipment, continuous grinding is achieved, the stable and long-service-life effect is achieved, the consumable cost can be saved by more than 20% compared with a traditional resin grinding wheel, and remarkable economic efficiency is achieved. According to the diamond grinding wheel, through the structural design, the overall weight of the diamond grinding wheel is equivalent to that of a resin grinding wheel sold in the market under the same working condition, the diamond grinding wheel can be directly matched with an existing grinding machine for use, the operation difficulty and complexity of existing equipment are greatly reduced, and operation and maintenance are easy.

Description

technical field [0001] The invention belongs to the technical field of superhard abrasive tools, and in particular relates to a diamond grinding wheel used for grinding the inner wall of a cast pipe. Background technique [0002] Cast pipe generally refers to ductile iron pipe, which has the essence of iron and the performance of steel, excellent anti-corrosion performance, good ductility, good sealing effect, easy installation, and is mainly used for water supply, gas transmission, oil transportation, etc. in municipal and industrial and mining enterprises. Generally, after the cast pipe is cast, the inner wall is not smooth, and there are casting residues or residues, which need to be polished and removed until the inner wall is smooth before spraying or coating can be performed. [0003] At present, a special inner wall grinder is mostly used for grinding the inner wall, that is, a long spindle, and a grinding wheel is installed at the end to penetrate into the inner wall...
