Problems solved by technology

At present, the resin cutting grinding wheel with a diameter of more than 300mm in the market has a product thickness of more than 3.0mm. Because the product is thicker, the material consumption is more, the opening is wider when cutting, and the loss of the processed material is also large. At the same time, the thicker the grinding wheel, the cutting resistance It is also large, the friction heat increases, and it is easy to burn the workpiece
The resin cutting grinding wheel in the prior art not only has high production cost, but also consumes a lot of energy during use. In addition, because the resin grinding wheel product is too thick, it also wears out too quickly during use and has a short service life.

Abstract

The invention discloses a large-diameter ultra-thin resin cutting grinding wheel. The large-diameter ultra-thin resin cutting grinding wheel comprises a reinforcing layer and a grinding layer; the reinforcing layer is glass fiber gridding cloth, the grinding layer is formed by combining abrasive material, a binding agent, padding and pigment according to the weight ratio of 90-130:10-35:3-20:0.2-3. The large-diameter ultra-thin resin cutting grinding wheel is obtained through mixing, forming and curing. The diameter of the large-diameter ultra-thin resin cutting grinding wheel ranges from 300to 500 mm, the thickness is 1.8+ / -0.3 mm, the production cost is reduced, the cutting opening is small, the cut material loss is reduced, the cutting efficiency is high, and the service life is long.

Description

technical field [0001] The invention belongs to the field of resin grinding wheels, in particular to a large-diameter ultra-thin resin cutting grinding wheel and a preparation method thereof. Background technique [0002] As a common cutting and grinding tool, the resin cutting grinding wheel has a wide range of applications, and can be used in the cutting and processing of round steel, flat steel, channel steel, steel pipe and other metal profiles. At present, the resin cutting grinding wheel with a diameter of more than 300mm in the market has a product thickness of more than 3.0mm. Because the product is thicker, the material consumption is more, the opening is wider when cutting, and the loss of the processed material is also large. At the same time, the thicker the grinding wheel, the cutting resistance It is also large, the frictional heat increases, and it is easy to burn the workpiece. The resin cutting grinding wheel in the prior art not only has high production co...
