Description
Technical Field
The invention relates to the technical field of fine grinding of hard and brittle materials, in particular to a diamond composite material and a preparation method and application thereof.
Background
The ultrahard materials such as zirconia ceramics and artificial sapphire have great potential in application to smart phones, such as fingerprint identification sheets, ceramic rear covers, lens protection sheets and the like. Hard material products are produced by fine grinding and polishing of the material surface to give it a shiny surface.
The surface polishing of the hard material needs to be carried out through three working sections of rough grinding, fine grinding and polishing, wherein the fine grinding process uses an abrasive material free type processing method, namely, diamond grinding fluid with the grain size of 2-4 mu m is dripped on a rotating plane copper disc, and the processed surface of a sample is pressed on the copper disc for processing. Because the metal copper has good ductility, part of diamond abrasive particles are embedded on the surface of a copper disc under the pressure action of a sample, the fixed abrasive particles act on the sample together with the abrasive rolling on the surface of the disc, and the surface of the sample is gradually polished. Occasionally, large sample particles are broken off during refining, and the superhard particles, if wandering across the disc, can scratch the entire batch of samples. Therefore, the key scheme for solving the problem of fine grinding processing scratch is as follows: a series of concentric annular shallow grooves with the depth of about 0.5mm, the width of about 1mm and the interval of about 1mm are engraved on the surface of the copper disc. Particles that fall off during processing will roll down into these shallow grooves rather than wandering over the disk surface. In addition, the shallow grooves on the disc surface cannot be too deep, otherwise, the grinding fluid cannot climb back to the copper disc surface, and the cutting efficiency is greatly reduced or even disappears.
The problems of the fine grinding processing by the copper disc are as follows: the copper disc is worn during use, so that the groove depth is reduced and the plane precision of the disc surface is reduced, and therefore the disc surface needs to be frequently grooved and trimmed. Meanwhile, the processing mode involves the use of a large amount of expensive diamond grinding fluid, and a lot of diamonds flow away without being fully utilized, so that the processing cost is high.
