Problems solved by technology
[0006] The above-mentioned technology of using holes to accommodate abrasive particles can only make the abrasive particles be positioned at a specific position, but cannot make the tip of the abrasive particles face upward and have the same amount of protrusion, and cannot use the shape of the hole itself to restrict the abrasive particles. Abrasive particles are hard to turn once positioned

Embodiment Construction
[0028] For other purposes and functions of the present invention, please refer to the drawings and embodiments, and the details are as follows.
[0029] see Figure 1-6 shown. The steering method with regular abrasives of the present invention comprises the following steps:
[0030] (a) On the flat plate 10, 20 respectively make a plurality of positioning units 11, 21 of polygonal cylindrical penetration holes, cylindrical penetration holes or tapered penetration holes, such as figure 1 , 2 , 3, 6 shown;
[0031] (b) Abrasive materials 30 of a plurality of polyhedrons are accommodated in a plurality of positioning units 11, 21 respectively, and a tip 31 of the abrasive material 30 protrudes from the first surfaces 101, 201 of the flat plates 10, 20, and the other of the abrasive material 30 A tip 32 protrudes from the second surface 102, 202 of the flat plate 10, 20 through the positioning unit 11, 21, such as figure 1 , 4 , as shown in 6;
[0032] (c) Fix and combine t...

Abstract
The invention relates to an abrasive steering method with rules and a product, a flat plate is provided with a plurality of positioning units with columnar through holes or conical through holes, abrasives of a plurality of polyhedrons respectively automatically fall into the plurality of positioning units through the mechanical force or the vibration method or the movement of the flat plate, the automatic steering is carried out for leading one tips of the abrasives to protrude from the first surface of the flat plate, and leading the other tips of the abrasives to penetrate the positioning units and protrude from the second surface of the flat plate, so that the abrasives can be conveniently combined with the flat plate according to the set arrangement pattern and the interval, the exposed height of the tip ends of the abrasives protruding from the flat plate is controlled by utilizing the size and the shape of the through holes of the positioning units, the abrasives are limited by utilizing the shape of the positioning units, and then the abrasives are difficult to rotate after being positioned.
Description
technical field [0001] The invention relates to a grinding tool, in particular to a method for regularly diverting abrasives in a grinding tool and a product thereof. Background technique [0002] All kinds of grinding tools are widely used in the processing of stone, cement, glass, brick, ceramics, metal and other materials. Especially for grinding tools used in wafer manufacturing, in order to obtain better grinding performance of CMP grinding pads, the particle size (Particle size), sharpness, arrangement pattern (Pattern) and spacing ( Pitch) and exposure height (Protrusion height) etc. need to be properly planned and configured. [0003] There are many technologies for regularly arranging or evenly distributing diamond particles and other abrasive particles on the substrate according to a pre-planned plan. For example, Chinese Taiwan patent I286097 discloses a grinding tool and its manufacturing method. The structure of the grinding tool includes a base material, A pl...
