Benefits of technology

[0036]Therefore, the present invention provides a template, the shape and the pattern of the template can be designed conveniently on the arranging requirement of abrasive particles, and the template can adsorb only single layer of abrasive particles, place the template with uniformly distributed abrasive particles into or adhere to sheet, then will form a sheet with uniformly distributed abrasive particles, thus the position of abrasive particles can be located exactly on the sheet on predetermination. The abrasive particles can be uniformly distributed, or arranged on the requirement of accounted cutting force of provided cutting and grinding tools, For example, higher concentration diamond grits

Problems solved by technology

Improper spacing of the abrasive particles will lead to premature failure of the abrasive surface or structure.
If the abrasive particles are too close to one another,

Embodiment Construction

[0044]FIG. 1 shows a perspective view of a segment of diamond tool, indicated at 10. The segment 10 is formed by a plurality of layers, 11, 12, 13, and 14, which are impregnated with abrasive grits, indicated as hexagonal frame 1.

[0045]Referring to FIGS. 2A, 2B, and 2C, electromagnetic template 20 of the present invention is capable of adsorbing single layer of abrasive particles (for example, diamond grits) after the corona is discharged. When the adsorptive points are occupied by the adsorbed diamond grits, the other grits can not be adsorbed on the same place, so the adsorbed grits form a single layer, and the template can be designed on the requirement of the arrangement of diamond or other abrasive particles. Thus the diamond, cubic boron nitride grits are uniformly distributed on the template, and the distribution form can be designed freely on the desire of the designers.

[0046]FIGS. 2A, 2B, and 2C are views of the distribution of abrasive particles on the template, wherein FI...

Abstract

The present invention relates to a method of uniformly distributing abrasive grits on grinding tools. It can be applied in the cutting, grinding segments of diamond tools, which are typically used in cutting and drilling various hard and fragile materials, such as granite, marble, concrete, asphalt, etc. The present invention provides a template, the template designed based on the arranging requirement of abrasive particles such as diamond grits. The template can adsorb only a single layer of abrasive particles and is then placed onto a sheet, where the diamond grits are pressed into the sheet, with the diamond grits distributed uniformly on the sheet.

Description

RELATED APPLICATIONS[0001]This is a continuation of International Application PCT / CN2008 / 000331, with an international filing date of Feb. 13, 2008.FIELD OF THE INVENTION[0002]The present invention relates to the cutting and grinding tools, such as the cutting segments of diamond tools, which are typically used in cutting and drilling various hard and fragile materials, such as granite, marble, concrete, asphalt, etc. More particularly, the present invention relates to the uniform distribution of abrasive particles such as diamond grits on the segments of cutting tools to increasing the cutting efficiency.BACKGROUND OF THE INVENTION[0003]Synthetic diamonds are the hardest abrasive material currently known, and they have been widely used as super-abrasives on cutting and grinding tools. Diamond tools are particularly used to cut and grind rocks in machining stone and other structural components. Diamond tools mainly have cutting segments on which diamonds or other abrasive particles ...
