Embodiment Construction
[0016] The sand planting of this type of coated abrasive is arranged according to regular and irregular geometric forms, and there is an obvious concave sand-free area between the regular and irregular geometric forms, that is, the automatic chip removal area. The length, width, and depth of the automatic chip removal area are set according to the use of the abrasive belt, that is, the length, width, and depth of the automatic chip removal area can meet the automatic chip removal during the grinding process. The substrate is any flexible substrate such as paper substrate, cloth substrate, film substrate, steel paper (vulcanized fiber) substrate or sponge (including EVA foam material). The specifications are ring-shaped, sheet-shaped, strip-shaped, roll-shaped or disc-shaped, and various shapes. The base body is a bendable base body.
[0017] The regular geometric form of the present invention has figure 1 The grinding area shown is arranged in a misplaced regular triangle, ...

The invention relates to an automatic chip removal grinding coated abrasive tool. The coating grain of the coated abrasive tool is arranged in regular geometric mode and irregular geometric mode. A non-grain zone which is obviously concaved downwards, namely an automatic chip removal zone, is placed between the position where the coating grain is arranged in regular geometric mode and the position where the coating grain is arranged in irregular geometric mode. The length, the width and the depth of the automatic chip removal zone are set according to the usefulness of an abrasive belt, namely the length, the width and the depth of the automatic chip removal zone can met the requirements of automatic chip removal during a grinding process. A base body which can be bent freely is a paper base body or a cloth base body or a membrane base body or a hard paper (vulcanized fiber) base body or a sponge (including ethylene-vinyl acetate copolymer (EVA) foam materials) base body and the like. The shape of the abrasive tool can be an annular-strip shape or a paper-piece shape or a strip shape or a coil shape or a circular disc shape or other various shapes. The coating grain of the coated abrasive tool is arranged in regular geometric mode and irregular geometric mode, the non-grain zone which is concaved downwards obviously, namely the automatic chip removal zone, is arranged between the position where the coating grain is arranged in regular geometric mode and the position where the coating grain is arranged in irregular geometric mode, during the grinding process, chips generated by grinding can be automatically removed from the automatic chip removal zone continuously, the problem that the chips generated by grinding blocks a sand surface is solved, grinding effect is improved, the service life of the abrasive belt is prolonged.
Description
technical field [0001] The invention relates to an automatic chip removal grinding coated abrasive tool. Background technique [0002] Grinding technology is often used in industrial production, and abrasive belts must be used for grinding. The abrasive surface structure of the abrasive belts currently used is as follows: Figure 8 As shown, the entire surface is a grinding area, and the gap between abrasives is very small, so during grinding, it is very easy to cause abrasive debris to block the sand surface, causing the sand surface to lose its grinding ability and be scrapped for use. cause waste and loss. Therefore, it is necessary to effectively solve the problem of grinding objects blocking the sand surface. [0003] The material ground from the workpiece fills the gap between the abrasive grains, causing the problem of abrasive belt clogging. The existing patent "ordered structure abrasive belt products and its manufacturing method" (Chinese Patent No. 92100694.2) in...
