[0030] see Figure 1 to Figure 3 , Figure 1 to Figure 3 They are respectively the structural schematic diagrams of the first embodiment of the elastic abrasive tool of the present invention, the first viewing angle, the second viewing angle and the third viewing angle. The elastic grinding tool is composed of a base 1, an elastic layer 2 and a grinding layer 3 connected in sequence. The base 1 is made of plastic material. The base 1 has a dovetail-shaped engaging part 11 for clamping to the head of the grinding machine. The elastic layer 2 is fixedly bonded to the base 1 by glue.

[0031] The model layer 3 includes 30 grinding blocks 31 arranged in a rectangular array, the 30 grinding blocks 31 are divided into 3 columns, and each column includes 10 grinding blocks 31 . The grinding block 31 protrudes from the elastic layer 2, and in the protruding direction of the grinding block, the cross-sectional area of ​​the grinding block gradually decreases from the extension start ...

Abstract

The invention provides an elastic grinding tool and a manufacturing method thereof. The elastic grinding tool comprises a base and a grinding layer fixed to the base. The grinding layer comprises a plurality of grinding blocks extending back on to the base. The grinding blocks are provided with grinding faces back on to the base. The multiple grinding faces are located on the same plane or cylindrical face. The grinding blocks comprise front portions and rear portions. In the extending direction of the grinding blocks, the rear portions are away from a working face relative to the front portions, and raw materials of the rear portions comprise pore formers. The manufacturing method comprises the steps of mixing and hot pressing. In the mixing step, first raw materials are mixed evenly, andsecond raw materials are mixed evenly and comprise the first raw materials and the pore formers. In the hot pressing step, the first raw materials and the second raw materials are put into a die sequentially and are subjected to hot pressing to form a blank block. According to the elastic grinding tool provided by the invention, grinding performance and the abrasion resistant degree are ensured at the earlier use stage, the effect that the sharpness of the elastic grinding tool is not attenuated can also be ensured at the later use stage, and the service life of the elastic grinding tool is prolonged while grinding performance is ensured.

Description

technical field [0001] The invention relates to a surface polishing abrasive, in particular to an elastic abrasive made of diamond resin material and a manufacturing method of the elastic abrasive. Background technique [0002] The existing elastic grinding tool is a diamond resin elastic grinding tool, which is used for polishing the surfaces of pottery, granite, marble and antique bricks. An existing elastic grinding tool includes a base and a grinding layer. The base is used to be installed on the grinding head of the grinding machine. Grinding blocks protruding from the seat, each grinding block has a grinding surface facing away from the base. [0003] The existing problem of this kind of elastic abrasive tool is that after the elastic abrasive tool is used for many times, the grinding block will be consumed, the air gap on the grinding surface will be blocked by grinding debris, and the heat dissipation capacity will deteriorate, which will make the grinding block Th...
