Abstract

The invention discloses a nano microcrystalline cubic nitrification boron nitride abrasive cloth and a method for making the same. The method comprises: metal layers are distributed at intervals and coated on both sides of a substrate correspondingly, and the nano microcrystalline cubic boron nitride is embedded in the metal layers. Because the upper side and the lower side of the substrate are coated, metal base layers are formed at intervals on the substrate, and the nano microcrystalline cubic boron nitride is embedded in the metal layers simultaneously, the firmness strength of the nano microcrystalline cubic boron nitride powder embedded in the metal layers is higher. The formed nano microcrystalline cubic nitrification boron nitride abrasive cloth has the advantages of abrasion resistance, long service life, wide processing range and high polishing and grinding precision. The coated metal base layers are arranged at intervals on the nano microcrystalline cubic nitrification boron nitride abrasive cloth to make the abrasive cloth have certain flexibility, so the abrasive cloth can be used for precisely polishing and grinding products with multi-curve surfaces and complicated shapes.

Description

technical field

[0001] The invention relates to an abrasive cloth and a manufacturing method thereof, in particular to an abrasive cloth with electrical properties and a manufacturing method thereof. Background technique

[0002] At present, the existing abrasive cloth is mainly used for grinding the surface of metal parts, wood products, stone water abrasive parts, etc. At present, the manufacturing process of commonly used abrasive cloth is to mix ordinary corundum and silicon carbide abrasives with organic binders, and then directly apply or Use a mold to heat press on the substrate of non-woven fabric (or other materials) to form abrasive cloth (such as figure 1 As shown), but the grain size of the abrasive cloth is coarse, not sharp, and the grinding strength is not enough, so it cannot be used for precision polishing; at the same time, because the abrasive is mixed with an organic binder, it is not resistant to high temperature, which affects the service life of the ab...
