Spiral grinding wheel with composite material fiber micro blade

Abstract

The invention discloses a spiral grinding wheel with a composite material fiber micro blade. The spiral grinding wheel comprises fiber micro blades, grinding belts, a thin-strip-shaped metal sheet, a blade grinding layer and a grinding wheel base body, each fiber micro blade has a zero anterior angle through blade grinding, the grinding belts are fixedly bonded on the thin-strip-shaped metal sheet by the fiber micro blades at equal intervals through electroplating orientation, and the blade grinding layer of the spiral grinding wheel is formed by a plurality of grinding belts which are bonded in a spiral groove of the grinding wheel base body and distributed in a spiral-belt-shaped manner. Zero anterior angle grinding processing is realized by utilizing the fiber micro blades, and generation of grinding heat is reduced; the grinding belts are distributed in a spiral-belt-shaped manner, so that chip containing space and chip discharging capability of the grinding wheel are increased, blockage of the grinding wheel is reduced, and grinding liquid is facilitated to enter a grinding area for lubricating and cooling. The spiral grinding wheel has the advantages that the spiral grinding wheel generates little grinding heat and is excellent in lubricating and cooling performance, a grinding blade is good in wearing-resistant performance, high in hardness, good in tenacity, reproducible and repairable and the like, and the spiral grinding wheel is suitable for high-efficiency precise processing of difficult-to-process materials such as hard and brittle materials.

Description

technical field [0001] The invention relates to a spiral grinding wheel with composite material fiber micro blades, in particular to a grinding tool for precise machining of non-metallic hard and brittle materials and metal difficult-to-machine materials. Background technique [0002] The grinding process has the advantages of high machining accuracy, good surface quality and wide processing range, so it is widely used in machining. In recent years, the wide application of emerging hard and brittle materials such as optical glass, ceramics, and single crystal silicon, and difficult-to-machine materials such as aluminum alloys and titanium alloys has promoted the rapid development of grinding processing technology. However, the geometric shape of the abrasive grains in the ordinary grinding wheel is irregular and randomly distributed, and most of them are processed with a negative rake angle, resulting in a large amount of grinding heat in the grinding area; in addition, the ...

Problems solved by technology

However, the edge of the grinding wheel groove is prone to wear, and it is difficult to perform regenerative repair; the radial opening of the grinding wheel is cooled, and the grinding fluid is injected radially from the grinding wheel into the grinding area through the microchannel, thereby improving the burn on the surface of the workpiece, but the microchannel is easy Blockage occurs, and the structure of the grinding wheel and liquid supply device is complicated, and the manufacturing cost is high
