Description

technical field

[0001] The invention relates to the technical field of coated abrasive products, in particular to a supersoft coated emery cloth and a manufacturing method thereof. Background technique

[0002] The existing coated abrasive products have many varieties and are widely used. With the development of science and technology, new grinding parts or grinding materials are produced, corresponding to the demand for grinding tools and grinding materials. At the same time, new materials can also become one of the raw materials for coated abrasive products, and are developed as new varieties of coated abrasive products to achieve new performance or new uses in the grinding process.

[0003] In the large-scale grinding operations of traditional woodworking and paint surfaces, there are various forms such as manual grinding, electric or pneumatic tool grinding, etc. In this type of grinding, it is often necessary to grind the workpiece surface such as holes and grooves, a...
