Description

[0001] Technical field: [0002] The invention relates to a multi-abrasive coordinated arrangement process based on hole template technology, which belongs to the field of superhard abrasive tool manufacturing. [0003] Background technique: [0004] Traditional fixed abrasive tools can be divided into resin bonds, ceramic bonds, metal bonds (including electroplating and sintering), diamond tools, etc. The overall level and ability of the processing industry has also changed the original appearance of the processing industry, but whether it is a single-layer electroplating or multi-layer sintered (thermally cured) diamond bonded abrasive tool, the abrasive is only mechanically embedded in the coating. Or in the matrix metal, the interface lacks the bonding force. In the high-efficiency grinding operation with a heavy load, the abrasive grains or the coating of the grinding wheel are easy to fall off. The exposed height and chip space are reduced, and the tools are easily block...

AI Technical Summary

Problems solved by technology

However, as the cutting progresses, part of the concrete powder and cutting chips adhere to the saw blade, resulting in a decrease in the exposure of the abrasive grains, a decrease in cutting efficiency, further damage to the diamond abrasive grains, and an increase in the temperature of the saw blade. , forming a vicious circle, causing the saw blade to be overloaded and unable to continue to use

The example shows that it is difficult for a single type of abrasive tool to exert long-term and stable characteristics in application, and a new preparation theory and preparation method are needed to improve the performance of brazed tools

[0007] With the in-depth research, it is found that for ferrous metal materials that are difficult to process, traditional single-type abrasive tools are difficult to process effectively. Brazed diamond tools have good heat dissipation performance when processing ferrous metal materials, but they are difficult to process efficiently and quickly because they are prone to high-temperature graphitization; Although brazed CBN (cubic boron nitride) tools have good performance in processing ferrous metals, they are prone to react with water when they encounter high temperatures during processing, reducing their performance. In most cases, they will be used in processing conditions. Coolant

Although the silicon carbide and aluminum oxide abrasives are sharp and have high surface quality, they are not suitable for high-end machine tool processing due to large wear and fast consumption.

At present, the research on brazing tools is mainly focused on the brazing of diamond abrasives, and the simultaneous brazing of various abrasives such as diamond abrasives, cubic boron nitride abrasives, silicon carbide abrasives, and aluminum oxide abrasives to produce longer life and higher processing efficiency. Studies of higher tools have not covered

In addition, the current market will encounter new processing problems such as a variety of composite materials and mixed structural materials. Traditional single-type tools, whether it is sintered tools, brazing tools, or electroplating tools, are difficult to process.

[0008] It is very difficult to arrange multiple abrasives in the same single-layer brazed tool, because the geometric shape of each abrasive is inconsistent, and it is difficult to arrange the abrasives uniformly by conventional arrangement technology, and in the When a variety of abrasives are arranged in coordination, the particle size of each abrasive is inconsistent, and it is difficult to achieve uniform distribution of each abrasive, and there may be a phenomenon that large-grained and small-sized abrasives cannot be evenly distributed

The traditional abrasive arrangement process mostly focuses on the orderly or multi-layer structure design of a single abrasive, and the requirements for the specifications and shapes of the abrasives are relatively consistent, and it has certain difficulties for different shapes of various abrasives.

[0009] In addition, there is no report on the brazing preparation process of single-layer tools with multiple abrasive arrangements, mainly because the current single abrasive arrangement technology is still under development, and there is still a certain degree of scientific transformation of actual production problems. Lag, a variety of abrasive arrangement theory and technology are still in the stage of theoretical proposal and improvement
