A Helical Grinding Wheel with Composite Fiber Microblades

Abstract

The invention discloses a spiral grinding wheel with fiber micro blades of composite materials, which comprises: fiber micro blades, a grinding belt, a thin metal sheet, a grinding layer, and a grinding wheel matrix. The grinding belt is oriented by electroplating of fiber micro blades, It is composed of equidistant and spaced controllable solidification on the thin metal sheet; the grinding layer of the spiral grinding wheel is made of several grinding belts bonded in the spiral groove of the grinding wheel base through epoxy resin , the fiber micro-blades are arranged in a spiral belt on the working surface of the grinding wheel; the grinding belt and the spiral groove are coated with a release agent, and when the grinding belt is worn out, it can be quickly replaced to achieve regenerative repair ; The fiber microblade is made of high hardness, high strength, and wear-resistant cemented carbide-diamond composite material. The invention has the advantages of less grinding heat generated, excellent lubricating and cooling properties, good grinding wear resistance, high hardness, good toughness and reproducible repair, and is suitable for high-efficiency and precise machining of difficult-to-machine 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-metal 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 particles in the ordinary grinding wheel is irregular and randomly distributed, resulting in a large amount of grinding heat in the grinding zone; in addition, the grinding contact area between the grinding wheel and the wo...

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 into the grinding area radially from the grinding wheel through the microchannel, thereby improving the burn on the surface of the workpiece, but the microchannel is prone to Blockage, and the structure of the grinding wheel and liquid supply device is complicated, and the manufacturing cost is high
